Örnek:

ClassName.php

<?php echo "This will crash all"; ?>

Başka bir dosyada ...

foreach ($FILENAMES_WITHOUT_DOT_PHP as $name => $value) {
    if (class_exists( $value )) {
      echo "ClassName exists...";
    }
    else {
      echo "ClassName doesn't exists....";
    }
}

The output of this code is: This will crash all

Instead of this: ClassName doesn't exists....
