Previous Comments: ------------------------------------------------------------------------ [2017-10-13 17:45:41] tbollinger at ivesinc dot com Thank you, your comment makes sense. I mistakenly thought that the prepended bar() would be interpreted and the require_once() would be executed. This can be closed as "not a bug". Thanks again for your time! ------------------------------------------------------------------------ [2017-10-12 23:40:28] requinix@php.net 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. ------------------------------------------------------------------------ [2017-10-12 20:13:46] tbollinger at ivesinc dot com Description: ------------ This bug requires three files to reproduce, since it is an issue with spl_autoload_register(), specifically the prepend argument, and require_once(). 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
