How To Remove First Element of Array in PHP - array_shift() Function

You can use the array_shift() function to remove the first element or value from an array. The array_shift() function returns the removed first value of array. If the array is empty (or the variable is not an array), the returned value is NULL.

This function shifts an element off the beginning of array.

Example:

$planets = array("Mercury", "Venus", "Earth", "Mars");
 
// Removing first array item
$planet = array_shift($planets);
