How to delete an element from an array in PHP and re-index the array?

The ‘unset’ function can be used to remove an element from the array and use the ‘array_values’ function that resets the indices of the array.

Example

<?php
   $my_arr = array( 'this', 'is', 'a', 'sample', 'only');
   echo"The array is ";
   var_dump($my_arr);
   unset($my_arr[4]);
   echo"The array is now ";
   $my_arr_2 = array_values($my_arr);
   var_dump($my_arr_2);
?>

Output

The array is array(5) {
   [0]=>
   string(4) "this"
   [1]=>
   string(2) "is"
   [2]=>
   string(1) "a"
   [3]=>
   string(6) "sample"
   [4]=>
   string(4) "only"
}
The array is now array(4) {
   [0]=>
   string(4) "this"
   [1]=>
   string(2) "is"
   [2]=>
   string(1) "a"
   [3]=>
   string(6) "sample"
}

An array is declared that contains string values. The array is displayed and the ‘unset’ function is used to delete a specific index element from the array. Then the array is displayed again to reflect the changes on the console.
