HOW THE QUIZ WORKS:

Clicking the ‘randomize’ button situated above the reference table generates a new table whereby the function descriptions, function syntaxes, and function return values are randomized. The quiz involves matching the function descriptions, function syntaxes, and function return values to the correct function name. Information relating to the randomization of table cells will be displayed for three seconds, before disappearing.

On a desktop computer, table elements are selected by left-clicking the desired table cell and holding the left click in the mouse down position for one second before releasing the left click. The text inside the table cell will turn red to indicate that the one-second mouse left-click has successfully selected a table cell. To then swap the selected table cell with the target table cell, simply repeat the one-second left mouse-click process on the target cell; the table cells will swap position. To de-select a table cell, simply repeat the one-second left mouse-click process on the original table cell.

To select a table element on a touchscreen device (mobile, tablet), simply touch the desired table cell and maintain the touch for one second before removing your finger from the screen. The text inside the table cell will turn red to indicate that the one-second touch has successfully selected a table cell. To then swap the selected table cell with the target table cell, simply repeat the one-second touch process on the target cell; the table cells will swap position. To de-select a table cell, simply repeat the one-second touch process on the original table cell.

Normal touchscreen scrolling behaviour is exhibited by the cells with a light green background; cells without a light green background will not respond to normal touchscreen scrolling. The table is positioned in such a way that the user can also initiate touchscreen scrolling by swiping to the right or left of the table.

When a row consists of the correct function name, function description, function syntax, and function return value, the background colour of the row will change from ‘transparent’ to ‘khaki’; this provides visual feedback that the row is complete.

Once the entire table is complete, a paragraph of feedback will congratulate the user and provide the following information: date and time of quiz commencement; date and time of quiz completion; and the length of time it took the user to complete the quiz.

PURPOSE:

This webpage serves two purposes:

It provides a reference table for the PHP FTP functions, with information extracted and condensed from w3schools.com and php.net.
It enables users to complete a quiz related to the PHP FTP functions.

USAGE:

For each FTP function there are four table cells of information: the function name; the function description; the function syntax; and the function return value. There are three layouts available – ‘mobile‘, ‘tablet‘, and ‘desktop‘.

Click the relevant button below to display the PHP FTP functions reference table, sized appropriately for the desired viewport. A ‘RANDOMIZE‘ button appears above the reference table once the viewport is selected; clicking this button facilitates the commencement of a quiz.

FUNCTION NAME	FUNCTION DESCRIPTION	FUNCTION SYNTAX	FUNCTION RETURN VALUE
`ftp_alloc()` [ftp_alloc – Allocates space for a file to be uploaded]	This function allocates space for a file to be uploaded by sending an ALLO command to the remote FTP server. Owing to the fact that many servers do not support this command, it is best to reserve this function for servers that explicitly require preallocation.	`ftp_alloc(ftp_stream, filesize, &result` [optional parameter – if a variable is provided, a textual representation of the server’s response will be returned by reference]`);`	`ftp_alloc()`: returns TRUE on success; FALSE on failure.
`ftp_append()` [ftp_append – Append content of a file to another file on the FTP server]	This function appends the content of a file to another file on the FTP server.	`ftp_append(ftp_resource, remote_file, local_file, mode` [optional parameter, with a default value of FTP_IMAGE]`);`	`ftp_append()`: returns TRUE on success, FALSE on failure.
`ftp_cdup()` [ftp_cdup – Changes to the parent directory]	This function navigates one level up the FTP directory structure; thus, it changes to the parent directory.	`ftp_cdup(ftp_stream);` [The `ftp_stream` parameter represents the link identifier of the FTP connection.]	`ftp_cdup()`: returns TRUE on success, or FALSE on failure.

`ftp_connect()` [ftp_connect – Opens an FTP connection]	This function opens an FTP connection to `host`.	`ftp_connect(host, port` [optional parameter]`, timeout` [optional parameter]`);` [`port` specifies an alternate port to connect to, with a default FTP port value of 21. `timeout` specifies the timeout in seconds for all subsequent network operations; the default value is 90. This value can be changed (`ftp_set_option()`) and queried (`ftp_get_option()`) at any time.]	`ftp_connect()`: returns an FTP stream on success; FALSE on error.
`ftp_delete()` [ftp_delete – Deletes a file on the FTP server]	This function deletes the file specified by `path` from the FTP server.	`ftp_delete(ftp_stream, path);`	`ftp_delete()`: returns TRUE on success; FALSE on failure.
`ftp_exec()` [ftp_exec – Requests execution of a command on the FTP server]	This function sends a SITE EXEC `command` request to the FTP server.	`ftp_exec(ftp_stream, command);`	`ftp_exec()`: returns TRUE if the command was successful [server responded with HTTP code 200]; FALSE otherwise.
`ftp_fget()` [ftp_fget – Downloads a file from the FTP server and saves to an open file]	This function downloads [‘gets’] `remote_file` from the FTP server and writes it to the given `file_pointer`.	`ftp_fget(ftp_stream, file_pointer, remote_file, mode` [optional parameter, with a default value of FTP_IMAGE]`, resume_pos` [optional parameter, with a default value of 0]`);` [`mode` specifies the mode of transport – must be either FTP_ASCII or FTP_BINARY. `resume_pos` specifies the position in `remote_file` to start downloading from.]	`ftp_fget()`: returns TRUE on success; FALSE on failure.
`ftp_fput()` [ftp_fput – Uploads from an open file to the FTP server]	This function uploads [‘puts’] the data from `file_pointer` to `remote_file` on the FTP server.	`ftp_fput(ftp_stream, remote_file, file_pointer, mode` [optional parameter, with a default value of FTP_IMAGE]`, startpos` [optional parameter, with a default value of 0]`);` [`mode` specifies the transfer mode, and must be either FTP_ASCII or FTP_BINARY. `startpos` specifies the position in `remote_file` to start uploading to.]	`ftp_fput()`: returns TRUE on success; FALSE on failure.
`ftp_get_option()` [ftp_get_option – Retrieves various runtime behaviours of the current FTP stream]	This function returns [‘gets’] the value for the requested `option` from the specified FTP connection.	`ftp_get_option(ftp_stream, option);` [`option` can be either FTP_TIMEOUT_SEC (returns the current timeout used for network-related operations) or FTP_AUTOSEEK (returns TRUE if this option is on; FALSE otherwise).]	`ftp_get_option()`: returns the value on success; FALSE and a warning if `option` is not supported.
`ftp_get()` [ftp_get – Downloads a file from the FTP server]	This function retrieves [‘gets’] `remote_file` from the FTP server, and saves it into `local_file`.	`ftp_get(ftp_stream, local_file, remote_file, mode` [optional parameter, with a default value of FTP_BINARY]`, resumepos` [optional parameter, with a default value of 0]`);` [The file specified by `local_file` will be overwritten if it already exists. The transfer `mode` must be either FTP_ASCII or FTP_BINARY. `resumepos` specifies the position in `remote_file` to start downloading from.]	`ftp_get()`: returns TRUE on success; FALSE on failure.
`ftp_login()` [ftp_login – Logs in to an FTP connection]	This function logs in to `ftp_stream`.	`ftp_login(ftp_stream, username, password);`	`ftp_login()`: returns TRUE on success; FALSE and a warning on failure.
`ftp_mdtm()` [ftp_mdtm – Returns the last modified time of the given file]	This function gets the last modified time of `remote_file`, located on an FTP server. Not all servers support this feature, and this function does not work with directories.	`ftp_mdtm(ftp_stream, remote_file);`	`ftp_mdtm()`: returns the last modified time as a Unix timestamp on success; -1 on failure.
`ftp_mkdir()` [ftp_mkdir – Creates a directory]	This function creates [‘makes’] the specified `directory` on the FTP server.	`ftp_mkdir(ftp_stream, directory);`	`ftp_mkdir()`: returns the newly-created directory name as a string on success; FALSE on error.

`ftp_nb_continue()` [ftp_nb_continue – Continues retrieving/sending a file (non-blocking)]	This function facilitates the continued retrieval/sending of a file from/to an FTP server in a non-blocking fashion.	`ftp_nb_continue(ftp_stream);`	`ftp_nb_continue()`: returns one of three values – FTP_FAILED; FTP_FINISHED; or FTP_MOREDATA.
`ftp_nb_fget()` [ftp_nb_fget – Retrieves a file from the FTP server and writes it to an open file (non-blocking)]	This function retrieves [‘gets’] `remote_file` from the FTP server in an asynchronous [‘non-blocking’] manner.	`ftp_nb_fget(ftp_stream, file_pointer, remote_file, mode` [optional parameter with a default value of FTP_IMAGE]`, resumepos` [optional parameter, with a default value of 0]`);` [`mode` specifies the transfer mode and must be either FTP_ASCII or FTP_BINARY. `resumepos` represents the position in `remote_file` to start downloading from.]	`ftp_nb_fget()`: returns one of three values – FTP_FAILED; FTP_FINISHED; or FTP_MOREDATA.

`ftp_nb_put()` [ftp_nb_put – Stores a file on the FTP server (non-blocking)]	This function uploads [‘puts’] `local_file` to the FTP server, in an asynchronous [‘non-blocking’] manner.	`ftp_nb_put(ftp_stream, remote_file, local_file, mode` [optional parameter, with a default value of FTP_IMAGE]`, startpos` [optional parameter, with a default value of 0]`);` [`mode` specifies the transfer mode and must be either FTP_ASCII or FTP_BINARY. `startpos` represents the position in `remote_file` to start uploading to.]	`ftp_nb_put()`: returns one of three values – FTP_FAILED; FTP_FINISHED; or FTP_MOREDATA.
`ftp_nlist()` [ftp_nlist – Returns a list of files in the given directory]	This function returns an array [a ‘numbered list’] of files in the given `directory` on the FTP server.	`ftp_nlist(ftp_stream, directory);` [`directory` represents the directory to be listed. This parameter can also include arguments, but is not escaped – so there may be some issues with filenames containing spaces and other characters.]	`ftp_nlist()`: returns an array of filenames from `directory` on success; FALSE on error.
`ftp_pasv()` [ftp_pasv – Turns passive mode on or off]	In passive mode data connections are initiated by the client rather than the FTP server — this may be needed if the client is behind a firewall. This function turns passive mode on or off, and can only be called after a successful login – otherwise it will fail.	`ftp_pasv(ftp_stream, pasv);` [If `pasv` is TRUE then passive mode is turned on; otherwise it is turned off.].	`ftp_pasv()`: returns TRUE on success; FALSE on failure.
`ftp_put()` [ftp_put – Uploads a file to the FTP server]	This function uploads [‘puts’] `local_file` into `remote_file` on the FTP server.	`ftp_put(ftp_stream, remote_file, local_file, mode` [optional parameter with a default value of FTP_IMAGE]`, startpos` [optional parameter with a default value of 0]); [`mode` specifies the transfer mode and must be either FTP_ASCII or FTP_BINARY. `startpos` represents the position in `remote_file` to start uploading to.]	`ftp_put()`: returns TRUE on success; FALSE on failure.
`ftp_pwd()` [ftp_pwd – Returns the current directory name]	This function returns the name of the present working directory of the FTP server.	`ftp_pwd(ftp_stream);`	`ftp_pwd()`: returns the current [‘present’] working directory name on success; FALSE on error.
`ftp_raw()` [ftp_raw – Sends an arbitrary command to an FTP server]	This function sends an unrefined [‘raw’] FTP command to the FTP server.	`ftp_raw(ftp_stream, command);`	`ftp_raw()`: returns the server’s response as an array of strings. No parsing is performed on the response string, and the success or otherwise of the command is not determined.
`ftp_rawlist()` [ftp_rawlist – Returns a detailed list of files in the given directory]	This function executes the FTP `LIST` command, and returns the result as an array.	`ftp_rawlist(ftp_stream, directory, recursive` [optional parameter, with a default value of FALSE]`);` [`directory` specifies the directory path, and may include arguments for the `LIST` command. If `recursive` is set to TRUE, the issued command will be `LIST -R`.]	`ftp_rawlist()`: returns an array where each element corresponds to one line of text on success; FALSE if `directory` is invalid. The output is not parsed; the system type identifier returned by `ftp_systype()` can be used to determine how the results should be interpreted.
`ftp_rename()` [ftp_rename – Renames a file or a directory on the FTP server]	This function renames a file or a directory on the FTP server.	`ftp_rename(ftp_stream, oldname, newname);`	`ftp_rename()`: returns TRUE on success; FALSE and an E_WARNING-level error on failure.
`ftp_rmdir()` [ftp_rmdir – Removes a directory]	This function removes the specified `directory` from the FTP server.	`ftp_rmdir(ftp_stream, directory);` [`directory` must be a relative or absolute path to an empty directory.]	`ftp_rmdir()`: returns TRUE on success; FALSE on failure.
`ftp_set_option()` [ftp_set_option – Set miscellaneous runtime FTP options]	This function controls [‘sets’] various runtime options for the specified `ftp_stream`.	`ftp_set_option(ftp_stream, option, value);` [`option` can take the form of FTP_TIMEOUT_SEC [default value of 90 seconds], FTP_AUTOSEEK [enabled by default], or FTP_USEPASVADDRESS.]	`ftp_set_option()`: returns TRUE if the `option` could be set; FALSE if not. A warning will be thrown if `option` is not supported, or the passed `value` doesn’t match the expected `value` for the given `option`.
`ftp_site()` [ftp_site – Sends a SITE command to the server]	This function sends the given SITE `command` to the FTP server. SITE commands vary from server to server and are useful for dealing with concepts like file permissions and group membership; these commands are not standardized.	`ftp_site(ftp_stream, command);` [`command` represents the SITE command. There may be some issues with filenames containing spaces and other characters since this parameter is not escaped.]	`ftp_site()`: returns TRUE on success; FALSE on failure.
`ftp_size()` [ftp_size – Returns the size of the given file]	This function returns the size of `remote_file` on the FTP server in bytes. This feature is not supported by all servers.	`ftp_size(ftp_stream, remote_file);`	`ftp_size()`: returns the file size on success; -1 on error.
`ftp_ssl_connect()` [ftp_ssl_connect – Opens a Secure SSL-FTP connection]	This function will succeed even if the server is not set up for SSL-FTP – or its certificate is invalid – since it opens an explicit SSL-FTP connection to the specified `host`. In these instances, the client will send the appropriate `AUTH FTP` command when `ftp_login()` is called — resulting in a `ftp_login()` failure. To make this function available (rather than ‘undefined’) on Windows you must compile your own PHP binaries, since both the ftp module and the OpenSSL support are required to be built statically into PHP.	`ftp_ssl_connect(host, port` [optional parameter, with a default value of 21]`, timeout` [optional parameter, with a default value of 90 (seconds)]`);` [`host` should have no trailing slashes and should not be prefixed with `ftp://`.]	`ftp_ssl_connect()`: returns a SSL-FTP stream on success; FALSE on error.
`ftp_systype()` [ftp_systype – Returns the system type identifier of the remote FTP server]	This function returns the system type identifier of the remote ftp server.	`ftp_systype(ftp_stream);`	`ftp_systype()`: returns the remote system type on success; FALSE on error.
