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.
