Which one would you use?
Basically I only want to get the 1st element from a array, that's it.

The array_shift() function removes the first element from an array, and returns the value of the removed element. Note: If the keys are numeric, all elements will get new keys, starting from 0 and increases by 1 (See example below).
PHP lets you create 2 types of array: Indexed arrays have numeric indices. Typically the indices in an indexed array start from zero, so the first element has an index of 0 , the second has an index of 1 , and so on.
JavaScript arrays are zero-indexed: the first element of an array is at index 0 , the second is at index 1 , and so on — and the last element is at the value of the array's length property minus 1 .
To remove the first element or value from an array, array_shift() function is used. This function also returns the removed element of the array and returns NULL if the array is empty.
Well, they do different things.
array_shift($arr) takes the first element out of the array, and gives it to you.
$arr[0] just gives it to you... if the array has numeric keys.
An alternative that works for associative arrays too is reset($arr). This does move the array's internal pointer, but unless you're using those functions this is unlikely to affect you.
