If you can't create a real simple self-contained script which reproduces this bug, it's likely to be an error in your script, and not in PHP. I really think it's a bogus, you're using foreach multiple times which is messy if you don't reset() at appropriate times. Reopen if this is not the case. ------------------------------------------------------------------------ [2001-12-20 03:13:51] TheWizardRK at yahoo dot com $tree = Array( [1] => Array ( [parentid] => 0, [name] => '1' ) [2] => Array ( [parentid] => 0, [name] => '2' ) [3] => Array ( [parentid] => 1, [name] => '1_1' ) [4] => Array ( [parentid] => 3, [name] => '1_1_1' ) [5] => Array ( [parentid] => 3, [name] => '1_1_2' ) [6] => Array ( [parentid] => 4, [name] => '1_1_1_1' ) [7] => Array ( [parentid] => 1, [name] => '1_2' ) [8] => Array ( [parentid] => 7, [name] => '1_2_1' ) [9] => Array ( [parentid] => 2, [name] => '2_1' ) ); // Recursion using a copy of the variable each time // WORKS function funktzia1($base,$dir) { foreach($dir as $id => $item) { if ($item[parentid]==$base) { echo "<UL>\n<LI>".$item[name]."</LI><BR>\n"; funktzia1($id,$dir); echo "</UL>\n"; } } } // Print the tree using the first function funktzia1(0,$tree); // Recursion using the same variable - pass by reference (note the "&" before the "$dir") // DOESN'T WORK function funktzia2($base,&$dir) { foreach($dir as $id => $item) { if ($item[parentid]==$base) { echo "<UL>\n<LI>".$item[name]."</LI><BR>\n"; funktzia2($id,$dir); echo "</UL>\n"; } } } // Print the tree using the second function funktzia2(0,$tree); ------------------------------------------------------------------------ [2001-12-19 18:31:46] [EMAIL PROTECTED] Please provide a compelte self-contained copy&paste ready script. Feedback. ------------------------------------------------------------------------ [2001-12-19 15:17:21] TheWizardRK at yahoo dot com 1. Actually doing a "reset()" doesn't work at all. 2. I thought that this was a duplicate of #5052 - but now I see that there's too different variables there for each level of the nested "foreach()" - and I use the same variable. So it seems that this is not a duplicate after all (corrent me if I'm wrong). ------------------------------------------------------------------------ [2001-12-19 15:00:55] TheWizardRK at yahoo dot com It seems that this has been pointed out before... Sorry. But this is still not solved (although the other bug reports about this are already marked as "closed"). :( I only saw a solution of using "reset()" in the end of the loop, but this doesn't seem to be a good solution. Any chances that each "foreach()" will be made to work on a new copy of the array, so that nested "foreach()" will work? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
