Bug #75369 [Opn->Fbk]: spl_autoload_register prepend not working with nested require_once

Edit report at https://bugs.php.net/bug.php?id=75369&edit=1 ID: 75369 Updated by: requinix@php.net Reported by: tbollinger at ivesinc dot com Summary: spl_autoload_register prepend not working with nested require_once -Status: Open +Status: Feedback Type: Bug Package: SPL related PHP Version: 7.1.10 Block user comment: N Private report: N New Comment: What is the bug, exactly? Why do you expect that behavior? If bar() is prepended during execution of foo() the autoload system isn't going to "go back" and use it, so when foo() ends FooBar won't be present. As you said, if you append instead of prepend then it works.

Removing the prepend argument displays the expected result. This was created using a base install of PHP 7.1.10. Test script: --------------- ---- file1.php ---- <?php function load() { spl_autoload_register('foo'); } function foo($class) { echo __FUNCTION__ . "\n"; require_once('./file2.php'); } load(); new FooBar(); ---- file2.php ---- <?php function bar($class) { echo __FUNCTION__ . "\n"; require_once('./file3.php'); } spl_autoload_register('bar', true, true); ---- file3.php ---- <?php class FooBar { public function __construct() { echo __CLASS__ . "\n"; } } Expected result: ---------------- foo bar FooBar Actual result: -------------- foo foo PHP Fatal error: Uncaught Error: Class 'FooBar' not found in /home/user/phptest/file1.php:5 Stack trace: #0 {main} thrown in /home/user/phptest/file1.php on line 5 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75369&edit=1
