#40050 [NEW]: Array assignment without references

From: BenBE at omorphia dot de Operating system: Windows 2K PHP version: 5.2.0 PHP Bug Type: Scripting Engine problem Bug description: Array assignment without references Description: ------------ When assigning an array by-value into itself PHP will insert a self-referencing Array into the new entry Reproduce code: --------------- $a = array(); $a[] =& $a; print_r($a); $b = array(); $b[] = $b; print_r($b); Expected result: ---------------- array(1) { [0]=> array(1) { [0]=> array(1) { [0]=> *RECURSION* } } } array(1) { [0]=> array(0) { } } $b[0] should contain an empty array because $b was assigned by-value, i.e. should get copied. Actual result: -------------- array(1) { [0]=> array(1) { [0]=> array(1) { [0]=> *RECURSION* } } } array(1) { [0]=> array(1) { [0]=> array(1) { [0]=> *RECURSION* } } } Comparing the references (see my entry regarding Spotting References) you find that $b and $b[0] are different pointers and $b[0] is an array like the one created in $a. -- Edit bug report at http://bugs.php.net/?id=40050&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40050&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40050&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40050&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40050&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40050&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40050&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40050&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40050&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40050&r=support Expected behavior: http://bugs.php.net/fix.php?id=40050&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40050&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40050&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40050&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40050&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40050&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40050&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40050&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40050&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40050&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40050&r=mysqlcfg
