Hi,

I am trying to update user A's password in the xml file. The password is in md5 hash format.

$new_password = md5($_POST['new_password']);


$sx = simplexml_load_file('check.xml');

print_r($sx);


Can someone tell me how to navigate to the user A's password and update the new password.




Thanks

Here's one way:

 
$sx = simplexml_load_file('check.xml');
$pass = $sx->xpath("/FileZillaServer/Users/User[@Name='A']/Option[@Name='Pass']");
$pass[0][0] = $new_password;
file_put_contents('check.xml', $sx->asXML());

Another way, although I'd go with xpath.

foreach ($xml->Users->User as $User) {
    if ($User->attributes()->Name == 'A') {
        foreach ($User->Option as $Option) {
            if ($Option->attributes()->Name == 'Pass') {
                $Option[0] = 'new md5';
                break 2;
            }
        }
    }
} 

Using a for loop instead of foreach for the outer loop could save significant memory if this file is large.
