Insert an Item at the Beginning of an Array in PHP

Inserting items to the end of an array is straightforward using $arr[] = $item. However, to insert an item at the beginning of an array, a different approach is required.

Solution: array_unshift()

To insert an item at the beginning of an array in PHP, use the array_unshift($array, $item) function. This function takes two arguments: the target array and the item to insert.

Example:

<code class="php">$arr = array('item2', 'item3', 'item4');
array_unshift($arr , 'item1');
print_r($arr);</code>

Output:

Array
(
 [0] => item1
 [1] => item2
 [2] => item3
 [3] => item4
)

As you can see, item1 has been successfully inserted at the beginning of the array, shifting the original elements to the right.
