Suppose you want to reverse the operation, here is a way to "ldap_unescape"

<?php

function ldap_unescape($string) {
    return
       
preg_replace_callback(
           
"/\\\\[\da-z]{2}/",
            function (
$matches) {
               
$match = array_shift($matches);
                return
hex2bin(substr($match, 1));
            },
           
$string
       
);
}

$result = ldap_unescape("uid=\\61\\6c\\70\\68\\6f\\6e\\7a\\6f,ou=people,dc=foo,dc=com"); // uid=alphonzo,ou=people,dc=foo,dc=com

?>

You can use it like this for filtering

<?php
$badSearchInput
= 'Domain\username';

$escapedSearchInput = ldap_escape($badSearchInput, null, LDAP_ESCAPE_FILTER);
?>
