Bug #75699 [NEW]: Conditional __autoload declaration always causes deprecation notice

From: scott dot vivian at gmail dot com Operating system: Ubuntu PHP version: 7.2.0 Package: Scripting Engine problem Bug Type: Bug Bug description:Conditional __autoload declaration always causes deprecation notice Description: ------------ If the __autoload function is declared in a branch that never gets executed, PHP still outputs a deprecation notice. The notice is a little haphazard and mostly only appears the first time a page is loaded. Subsequent refreshes don't show the notice until a restart. Also, it doesn't occur if you run the script below directly, only if you include it from another script (i.e. autoload.php contains the code below, and test.php includes autoload.php). Test script: --------------- <?php if (version_compare(PHP_VERSION, '5.1.2', '>=')) { // use spl_autoload_register() } else { function __autoload($classname) { echo 'called autoloader'; } } Expected result: ---------------- No deprecation notice on PHP 7.2, because the else clause doesn't run and so the function is not defined. Actual result: -------------- Deprecated: __autoload() is deprecated, use spl_autoload_register() instead in /path/autoload.php on line 6 Appears the first time the page is viewed, disappears after that. -- Edit bug report at https://bugs.php.net/bug.php?id=75699&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75699&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75699&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75699&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75699&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75699&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75699&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75699&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75699&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75699&r=support Expected behavior: https://bugs.php.net/fix.php?id=75699&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75699&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75699&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75699&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75699&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75699&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75699&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75699&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75699&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75699&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75699&r=mysqlcfg
