Bug #15663 Updated: add foreach reference values

ID: 15663 Updated by: yohgaki@php.net Reported By: greg@mtechsolutions.ca -Status: Open +Status: Closed Bug Type: Feature/Change Request PHP Version: 4.1.1 New Comment: This bug has been fixed in CVS. ZendEngine2 uses handle for object. Previous Comments: ------------------------------------------------------------------------ [2002-02-21 17:20:05] mfischer@php.net Objects are bad examples as they will completely change how they behave in ZE2. However, it is true for normal arrays and it's in the TODO list of PHP: "Zend ---- * allow foreach ($array as $k => &$val) syntax. right now we cannot traverse an array without copying each element." ------------------------------------------------------------------------ [2002-02-21 12:34:00] greg@mtechsolutions.ca Just a small request that could be fairly useful. Say you have an array of objects, $objects. Right now, doing: foreach ($objects as $obj) { $obj->something(); } will create a copy of each object (using unnecessary memory) and call something() on the copy, not the actual object (which is bad if it's a mutator function of that class). The best way to do it now is to do: foreach (array_keys($objects) as $key) { $objects[$key]->something(); } but it would be very cool if php had the syntax: foreach ($objects as &$obj) where it would create $obj as a reference to each object. thanks ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15663&edit=1
