Class: WP_Filesystem_SSH2  - X-Ref

WordPress Filesystem Class for implementing SSH2

To use this class you must follow these steps for PHP 5.2.6+

{@link http://kevin.vanzonneveld.net/techblog/article/make_ssh_connections_with_php/ - Installation Notes}

Compile libssh2 (Note: Only 0.14 is officially working with PHP 5.2.6+ right now, But many users have found the latest versions work)

cd /usr/src
wget https://www.libssh2.org/download/libssh2-0.14.tar.gz
tar -zxvf libssh2-0.14.tar.gz
cd libssh2-0.14/
./configure
make all install

Note: Do not leave the directory yet!

Enter: pecl install -f ssh2

Copy the ssh.so file it creates to your PHP Module Directory.
Open up your PHP.INI file and look for where extensions are placed.
Add in your PHP.ini file: extension=ssh2.so

Restart Apache!
Check phpinfo() streams to confirm that: ssh2.shell, ssh2.exec, ssh2.tunnel, ssh2.scp, ssh2.sftp  exist.

Note: As of WordPress 2.8, this utilizes the PHP5+ function `stream_get_contents()`.

__construct( $opt = '' )   X-Ref
Constructor.

param: array $opt

connect()   X-Ref
Connects filesystem.

return: bool True on success, false on failure.

sftp_path( $path )   X-Ref
Gets the ssh2.sftp PHP stream wrapper path to open for the given file.

This method also works around a PHP bug where the root directory (/) cannot
be opened by PHP functions, causing a false failure. In order to work around
this, the path is converted to /./ which is semantically the same as /
See https://bugs.php.net/bug.php?id=64169 for more details.

return: string The ssh2.sftp:// wrapped path to use.
param: string $path The File/Directory path on the remote server to return

run_command( $command, $returnbool = false )   X-Ref

return: bool|string True on success, false on failure. String if the command was executed, `$returnbool`
param: string $command
param: bool   $returnbool

get_contents( $file )   X-Ref
Reads entire file into a string.

return: string|false Read data on success, false if no temporary file could be opened,
param: string $file Name of the file to read.

get_contents_array( $file )   X-Ref
Reads entire file into an array.

return: array|false File contents in an array on success, false on failure.
param: string $file Path to the file.

put_contents( $file, $contents, $mode = false )   X-Ref
Writes a string to a file.

return: bool True on success, false on failure.
param: string    $file     Remote path to the file where to write the data.
param: string    $contents The data to write.
param: int|false $mode     Optional. The file permissions as octal number, usually 0644.

cwd()   X-Ref
Gets the current working directory.

return: string|false The current working directory on success, false on failure.

chdir( $dir )   X-Ref
Changes current directory.

return: bool True on success, false on failure.
param: string $dir The new current directory.

chgrp( $file, $group, $recursive = false )   X-Ref
Changes the file group.

return: bool True on success, false on failure.
param: string     $file      Path to the file.
param: string|int $group     A group name or number.
param: bool       $recursive Optional. If set to true, changes file group recursively.

chmod( $file, $mode = false, $recursive = false )   X-Ref
Changes filesystem permissions.

return: bool True on success, false on failure.
param: string    $file      Path to the file.
param: int|false $mode      Optional. The permissions as octal number, usually 0644 for files,
param: bool      $recursive Optional. If set to true, changes file permissions recursively.

chown( $file, $owner, $recursive = false )   X-Ref
Changes the owner of a file or directory.

return: bool True on success, false on failure.
param: string     $file      Path to the file or directory.
param: string|int $owner     A user name or number.
param: bool       $recursive Optional. If set to true, changes file owner recursively.

owner( $file )   X-Ref
Gets the file owner.

return: string|false Username of the owner on success, false on failure.
param: string $file Path to the file.

getchmod( $file )   X-Ref
Gets the permissions of the specified file or filepath in their octal format.

return: string Mode of the file (the last 3 digits).
param: string $file Path to the file.

group( $file )   X-Ref
Gets the file's group.

return: string|false The group on success, false on failure.
param: string $file Path to the file.

copy( $source, $destination, $overwrite = false, $mode = false )   X-Ref

move( $source, $destination, $overwrite = false )   X-Ref
Moves a file or directory.

After moving files or directories, OPcache will need to be invalidated.

If moving a directory fails, `copy_dir()` can be used for a recursive copy.

Use `move_dir()` for moving directories with OPcache invalidation and a
fallback to `copy_dir()`.
