FilesystemUtil::is_usable_ftp_filesystem │ private static │ WC 1.0

Check if an FTP-based filesystem instance is usable.

Checks both the connection resource and the error state. The connection resource can be null if PHP's max execution time interrupted ftp_connect() before it completed, leaving the instance in a broken state without errors.

Method of the class: FilesystemUtil{}

No Hooks.

Returns

true|false. False if FTP-based and unusable, true otherwise.

Usage

$result = FilesystemUtil::is_usable_ftp_filesystem( $wp_filesystem ): bool;
$wp_filesystem(WP_Filesystem_Base) (required)
The filesystem instance to check.
