Question

I have an array:

$array=array('key1'=>'value1','key2'=>'value2','value3');

and a foreach:

foreach($array as $v){
     //do something
}

Is there a way to know in the foreach which element we are parsing?

(without doing something like:)

$count=0;
foreach($array as $v){
    $count++;
    // do something
}

thanks

EDIT1:

Sorry maybe I was not clear:
I don’t want know the key, but I need to know how many elements are left in the foreach. (that’s why I did the example with $count)

Yes, sort of.

foreach($array as $key=>$value) 
//  code
}

$key will be the array key, although if you want an actual integer count of iterations, and the keys are not numbered sequentially, or are strings, you will have to use a counter like in your original post.

Edit: to handle the last element without implementing a counter, you can use (if keys are int)

 $foo = ($key == count($array)-1) ? "last element" : "any other element";

(janked from the manual comments – http://php.net/manual/en/control-structures.foreach.php)

Edit: if your keys are not integers, you can create a counter like you have in your code above, and substitute $key with your counter variable.
