PHP 4.0 Bug #8373 Updated: foreach by reference

ID: 8373 Updated by: cynic Reported By: ocomte@guarantycity.com Old-Status: Open Status: Duplicate Bug Type: Feature/Change Request Assigned To: Comments: dupe of #3074 btw, +1 for foreach( $a as &$v ) :) Previous Comments: --------------------------------------------------------------------------- [2000-12-22 05:47:53] ocomte@guarantycity.com It would be very useful (at least for me) if the fonction foreach support references. For example the code : <? class Foo { var $Ok=false; function EchoOk() { if ($this->Ok) echo "OK<br>n"; else echo "KO<br>n"; } } $Bar=array(); $Bar[]=new Foo; foreach($Bar as $v) $v->SetOk(); foreach($Bar as $v) $v->EchoOk(); ?> will produce the output : KO<br> I know I can replace the first loop by : foreach($Bar as $k => $v) $Bar[$k]->SetOk(); but, in this case, the $v is useless. I suggest to accept the notation foreach($Arr as &$RefVal) and foreach($Arr as $Key => &$RefVal) in a future PHP release to make $RefVal a reference on each $Arr elements (and not a copy). --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=8373
