Example#1 Basic example
This example demonstrates how to check out a directory from a repository to a directory named calc:
<?php
svn_checkout('http://www.example.com/svnroot/calc/trunk', dirname(__FILE__) . '/calc');
?>
The dirname(__FILE__) call is necessary in order to convert the calc relative path into an absolute one. If calc exists, you can also use realpath() to retrieve an absolute path.
