Req #54207 [NEW]: autoload parameter for class_alias?

From: Operating system: PHP version: 5.3.5 Package: Performance problem Bug Type: Feature/Change Request Bug description:autoload parameter for class_alias? Description: ------------ While inspecting the class_alias() functionality I discovered that when declaring an alias of a class, it invokes an __autoload routine for all base class tree even if the aliased class not used in code. It may be inappropriate for huge frameworks when them used for quick/small/performance scripts that does not need alias functionality. Test script: --------------- A.php: class A { } B.php: class B extends A { } C1.php: class C1 extends B { } C2.php: class C2 extends B { } main.php: function __autoload($className) { include($className . '.php'); } function included_files() { return implode(', ', array_map('basename', get_included_files())) . "\n"; } echo included_files(); class_alias('C1', 'C'); echo included_files(); $c = new C(); echo included_files(); Expected result: ---------------- main.php main.php main.php, C1.php, B.php, A.php Actual result: -------------- main.php main.php, C1.php, B.php, A.php main.php, C1.php, B.php, A.php -- Edit bug report at http://bugs.php.net/bug.php?id=54207&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54207&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54207&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54207&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54207&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54207&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54207&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54207&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54207&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54207&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54207&r=support Expected behavior: http://bugs.php.net/fix.php?id=54207&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54207&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54207&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54207&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54207&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54207&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54207&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54207&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54207&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54207&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54207&r=mysqlcfg
