From: alex at avannaproductions dot com Operating system: MacOS X 10.3 PHP version: Irrelevant PHP Bug Type: Arrays related Bug description: array_merge loses references
Description: ------------ I'm not sure if this is a bug or actual accepted behavior, but array_merge seems to lose references. (I would assume array_merge_recursive does too, but I've not tested that.) I think it would be ideal behavior if this did not happen, as I've just come upon a real world situation where my desired behavior would be very useful. Test on both PHP 4.3.6 and July 10th snapshot of PHP 5. Reproduce code: --------------- $one=array(1,2,3); $two=array(4,5,6); $three=&$two; foreach($one as $val) echo "$val<br>"; foreach($three as $val) echo "$val<br>"; echo "-------------<br>"; $four=array_merge($one,&$three); $two[0]="x"; $two[1]="x"; $two[2]="x"; foreach($four as $val) echo "$val<br>"; Expected result: ---------------- 1 2 3 4 5 6 ------------- 1 2 3 x x x Actual result: -------------- 1 2 3 4 5 6 ------------- 1 2 3 4 5 6 -- Edit bug report at http://bugs.php.net/?id=29095&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=29095&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=29095&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=29095&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=29095&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=29095&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=29095&r=needscript Try newer version: http://bugs.php.net/fix.php?id=29095&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=29095&r=support Expected behavior: http://bugs.php.net/fix.php?id=29095&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=29095&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=29095&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=29095&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=29095&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=29095&r=dst IIS Stability: http://bugs.php.net/fix.php?id=29095&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=29095&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=29095&r=float
