Walk an Array with references

[Anon]

I've got an array of objects that I'm trying to walk through and change each object. Something like:

while(list($key,$value)=each($objects)) {
$value->changeMe('foo');
}

The problem with the above is that it appears that each returns a copy of the object in the array, so changing it inside the loop with $value->changeMe doesn't change the object in the $objects array.

I've tried:
while(list($key,)=each($objects)) {
$value =& $objects[$key];
$value->changeMe('foo');
}

This seems to work. I'm looking for confirmation that I'm not missing something, and hopefully a more elegant way to do this. I was hoping that
while(list($key,&$value)=each($objects)) {
...
would work, but it yields a parse error.
PHP 4.0.2.

Thanks.

...
would work, but it yields a parse error.

what you can try is:

while(list($key, $value) = each($objects)) {
&$value->changeMe('foo');
}

I've never tried any such code so far, but I'm pretty sure this will work.

Nope. Tried that. The code you suggested yields a parse error. I'm also fairly certain that the copy happens in the list()=each() stmt, so trying to reference after that is probably hopeless - too late to make a difference.
Thanks for the idea anyway.
