PHP Manual: Set miscellaneous runtime FTP options

Description

true ftp_set_option(FTP\Connection $ftp, int $option, intbool $value)

This function controls various runtime options for the specified FTP connection.

Parameters

ftp

An FTP\Connection instance.

option

Currently, the following options are supported:

**Supported runtime FTP options**
`FTP_TIMEOUT_SEC`	Changes the timeout in seconds used for all network related functions. `value` must be an integer that is greater than 0. The default timeout is 90 seconds.
`FTP_AUTOSEEK`	When enabled, GET or PUT requests with a `resumepos` or `startpos` parameter will first seek to the requested position within the file. This is enabled by default.
`FTP_USEPASVADDRESS`	When disabled, PHP will ignore the IP address returned by the FTP server in response to the PASV command and instead use the IP address that was supplied in the ftp_connect(). `value` must be a boolean.

value

This parameter depends on which option is chosen to be altered.

Return Values

Always returns true.

Errors/Exceptions

A ValueError is thrown if the option is not supported. A TypeError is thrown if the passed value doesn't match the expected type for the given option.

Changelog

Version	Description
8.5.0	The return type is `true` now; previously, it was bool.
8.1.0	The `ftp` parameter expects an FTP\Connection instance now; previously, a resource was expected.
