(PHP 5 >= 5.3.0)
class_alias — Creates an alias for a class
http://php.net/manual/en/function.class-alias.php

For (PHP 5 < 5.3.0) you can use following:

<?php
if ( ! function_exists('class_alias')) {
    function
class_alias($original, $alias) {
        eval(
'abstract class ' . $alias . ' extends ' . $original . ' {}');
    }
}

class_alias('print_r', 'printr');
?>
