It should be noted, that calling spl_autoload_call on a child class, and then on its parent class, throws a fatal error.

This happens because autoloading the child class also loads the class it extends. And since spl_autoload_call forcibly calls the registered autoload function(s), not taking into account whether the class exists, a fatal error is thrown:

File: child.class.php

<?php
class Child extends Parent () {
    public function __construct () {
        parent::__construct();
    }
}
?>

File: parent.class.php

<?php
class Parent () {
    public function __construct () {

    }
}
?>

File: autoload.php

<?php

/*    works fine    */
    spl_autoload_call('Child');

/*    throws: Fatal error: Cannot redeclare class Parent in /parent.class.php on line 2    */
    spl_autoload_call('Parent');

?>

Example:

<?php
spl_autoload_register(function($className) {
    var_dump($className);
});

//Output: ManuallyCalledClass
spl_autoload_call('ManuallyCalledClass');
?>
