foreach() in PHP

[Guest vegras]

this is my first post here, so hi. i decided to get around to learning PHP last night, since i'm getting tired of ASP... one of the first problems i ran into in my code was getting the current array position inside a foreach() loop based on that same array. i'm not sure why, but key() was returning the value of the array element instead of the array position, or something weird like that. anyhow, i talked to some fine people who knew the language much better than i do, and was informed about another way of calling the function:foreach($x as $y => $z) { };where $x is the array foreach() is looping through, $y is the current element's position/index value, and $z is the current element's data value. given that it gives you extremely easy access to the index without calling another function on every pass of the loop, i was rather surprised to learn it wasn't in the PHP Loops tutorial. so i'd like to suggest it be added, although you may have guessed that. [edit: the comma between $x and $y should have been "as", thanks DTP]

yea, I think they should. I never even learned about that lol..

Are you sure it can be called like that? Because I've learned it this way:

foreach ($array as $key => $value) {}

In the javascript tutorial this loop wasn't explained from the beginning either

I have been using C# for almost 2 years now and just realised it has a foreach loop....man, it would have saved me a bunch of time over the last 2 years...lol
