svn_update — Update working copy

### Description

int svn_update ( string `$path` [, int `$revno` [, bool `$recurse` ]] )

Update working copy at `path` to revision `revno` . If `recurse` is true, directories will be recursively updated.

### Parameters

`path`

  Path to local working copy.

  > Note: Relative paths will be resolved as if the current working directory was the one that contains the PHP binary. To use the calling script's working directory, use realpath() or dirname(__FILE__).

`revno`

  Revision number to update to, default is `SVN_REVISION_HEAD`.

`recurse`

  Whether or not to recursively update directories, default is `TRUE`.

### Return Values

Returns new revision number on success, returns `FALSE` on failure.
