Arrays: array_shift($arr) or $arr[0]?

Question

Which one would you use?

Basically I only want to get the 1st element from a array, that\'s it.

Answer 1

$arr[0] only works if the array as numerical keys.

array_shift removes the element from the array and it modifies the array itself.

If you are not sure what the first key is , and you do not want to remove it from the array, you could use:

$v){
   $value = $v;
   break;
}

or even better:
