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? Previous Comments: ------------------------------------------------------------------------ [2001-12-19 14:46:50] [EMAIL PROTECTED] I have a tree, which is loaded into a variable into the following (hopefully self-explanatory) structure: 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 ) ) This results in the following three: + 1 + 1_1 + 1_1_1 + 1_1_1_1 + 1_1_2 + 1_2 + 1_2_1 + 2 + 2_1 I have the following recursive function to draw this tree: function funktzia($base,$dir) { foreach($dir as $id => $item) { if ($item[parentid]==$base) { echo "<UL>\n<LI>".$item[name]."</LI><BR>\n"; funktzia($id,$dir); echo "</UL>\n"; } } } where `$base' is the current tree node id, and `$dir' is the variable which holds the tree, as described above. The function is initially called "funktzia(0,$tree);", and the recursively calls itself. So far so good. But if the `$dir' variable is a by-reference parameter (i.e. "[...] &$dir [...]" instead of "[...] $dir [...]" as now), or it is defined global within the function instead of being passed as a parameter (in either way, all recursion level use the same variable) - it doesn't work. It draw the tree only while going up levels, but stop when it's time to go back to a lower level. Or in short, the following tree is drawn instead of the full one: + 1 + 1_1 + 1_1_1 + 1_1_1_1 It seems that when we go back to the lower "foreach" loop, the array pointer it uses already points to the end of the array (since we just finished doing a "foreach" loop on that array in the higher level). ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=14607&edit=1 -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
