From: beat at joomlapolis dot com Operating system: osX 10.6.8 PHP version: 5.3.14 Package: Class/Object related Bug Type: Bug Bug description:callback of private function in parent class works but static vars are lost
Description: ------------ In the case below where the callback function is private, its static local variable is lost during call of inherited class, t if the callback function is private as below, it still gets called, but the local static variable is null instead of initialized like in PHP 5.2, where it works. Also if you make the callback function "protected" instead of "private", the result is correct, as expected. This is reproducible at least on PHP 5.3.8. Test script: --------------- class ok { public function t() { $this->replacer( '*' ); return preg_replace_callback( '/(t)/', array( $this, 'replacer'), 'this is a simple test' ); } private function replacer( $input ) { static $cache = '-'; if ( ! is_array( $input ) ) { $cache = $input; } else { return $cache . $input[1] . $cache; } } } class buggyphp extends ok {} class buggyphptoo extends ok { public function t() { return parent::t(); } } $buggy = new buggyphp(); echo 'Result buggyphp: ' . $buggy->t(); echo "\n"; $buggy = new buggyphptoo(); echo 'Result buggyphptoo: ' . $buggy->t(); echo "\n"; $a = new ok(); echo 'Result ok: ' . $a->t(); exit(); Expected result: ---------------- Result buggyphp: *t*his is a simple *t*es*t* Result buggyphptoo: *t*his is a simple *t*es*t* Result ok: *t*his is a simple *t*es*t* Actual result: -------------- Result buggyphp: -t-his is a simple -t-es-t- Result buggyphptoo: -t-his is a simple -t-es-t- Result ok: *t*his is a simple *t*es*t* -- Edit bug report at https://bugs.php.net/bug.php?id=62547&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=62547&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=62547&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=62547&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=62547&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=62547&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=62547&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=62547&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=62547&r=needscript Try newer version: https://bugs.php.net/fix.php?id=62547&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=62547&r=support Expected behavior: https://bugs.php.net/fix.php?id=62547&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=62547&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=62547&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=62547&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=62547&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=62547&r=dst IIS Stability: https://bugs.php.net/fix.php?id=62547&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=62547&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=62547&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=62547&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=62547&r=mysqlcfg
