Detecting the rmdir error with php

Question

rmdir() displays a few warnings like the dir does not exist, or permissions did not allow. How can I capture which reason for failure and react to it?

Answer 1

rmdir does not throw Exception so you cannot catch them with try/catch. What you can do is use error_get_last function to do what you need.

Try something like this:

if (!@rmdir('/root')) {
    $error = error_get_last();

    if (preg_match('/something/', $error['message'])) {
        // do something
    } elseif (preg_match('/somethingelse/', $error['message'])) {
        // do something
    }
}
