#42994 [NEW]: is_callable and __autoload

From: arnout at argeweb dot nl Operating system: BSD PHP version: 5.2.4 PHP Bug Type: Unknown/Other Function Bug description: is_callable and __autoload Description: ------------ When using is_callable on non-existing static class functions __autoload will be called twice with some encoded (and thus non-existent) classname. Reproduce code: --------------- autoload.php <?php class test{ function notest(){ } } function __autoload( $classname ){ echo "let's require $classname!<br/>\n"; } if( is_callable( array( 'test', 'test' ) ) ){ echo "test::test exists."; }else{ echo "test::test doesn't exist."; } ?> Expected result: ---------------- test::test doesn't exist. (no __autoload execution at all) Actual result: -------------- let's require 9akf! let's require 9akf! test::test doesn't exist. -- Edit bug report at http://bugs.php.net/?id=42994&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42994&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42994&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=42994&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42994&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42994&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42994&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42994&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42994&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42994&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42994&r=support Expected behavior: http://bugs.php.net/fix.php?id=42994&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42994&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42994&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42994&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42994&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42994&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42994&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42994&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42994&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42994&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42994&r=mysqlcfg
