    PHP – get class name and file name from an object

    By admin on Jan 7, 2016

    PHP – get class name of an object

    get_class with object as arguments returns its class name.

    <?php
    class Class1 {
    }
    $obj = new Class1();
    echo "class name of obj=" . get_class($obj);
    ?>
    class name of obj=Class1
    Env: PHP 7.4.33 (Linux)

    PHP – get filename from class name

    <?php
    $classname = 'WP_Query';
    $reflector = new ReflectionClass($classname);
    echo $reflector->getFileName();
    ?>

    Here is the outcome from above code:

    /path_to_word_press_root/wp-includes/query.php
    


    Note: This can be useful to debug large code base.
