How to find a reason when mkdir fails from PHP?

Question

PHP\'s mkdir function only returns true and false. Problem is when it returns false.

If I\'m running with error reporting enabled, I see the error message on the scr

Answer 1

I use something like the following:

if(! @mkdir('$fileLocation', 0777, $recursive = true)){
    $mkdirErrorArray = error_get_last();
    throw new Exception('cant create directory ' .$mkdirErrorArray['message'], 1);
}

Answer 2

You could use exceptions:

Setup some code like so:

function exception_error_handler($errno, $errstr, $errfile, $errline ) {
    throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
}
set_error_handler("exception_error_handler");

And then just do:

try {
   mkdir('/somedir');
} catch(ErrorException $ex) {
   echo "Error: " . $ex->getMessage();
}

That should do what you want.

If you want to preserve the php error handler, then after that try catch block, just call:

restore_error_handler()

Answer 3

You can suppress the warning and make use of error_get_last():

if (!@mkdir($dir)) {
    $error = error_get_last();
    echo $error['message'];
}
