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

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."PHP5 has support for traversing arrays with objects and getting not a copy but a reference : foreach ($a as &$v) { } Example code : <?php $a = array((object)1, (object)2,(object)3,(object)4); var_dump($a); foreach ($a as &$v) { $v->scalar++; } var_dump($a); ?>
