PHP - Getting the index of a element from a array

Question

How can I get the current element number when I\'m traversing a array?

I know about count(), but I was hoping there\'s a built-in function for getting the current field

Answer 1

an array does not contain index when elements are associative. An array in php can contain mixed values like this:

$var = array("apple", "banana", "foo" => "grape", "carrot", "bar" => "donkey");   
print_r($var);

Gives you:

Array
(
    [0] => apple
    [1] => banana
    [foo] => grape
    [2] => carrot
    [bar] => donkey
)

What are you trying to achieve since you need the index value in an associative array?
