How can you delete a specific value element in a PHP array?

To remove a specific value element from an array in PHP, you can use the array_search() function to find the key of that value in the array, and then use the unset() function to remove the element corresponding to that key.

Here is an example code:

<?php
$array = array(1, 2, 3, 4, 5);

$value = 3;
$key = array_search($value, $array);
if ($key !== false) {
    unset($array[$key]);
}

print_r($array);
?>

The output is:

Array
(
    [0] => 1
    [1] => 2
    [3] => 4
    [4] => 5
)

In the example above, we are removing the element with a value of 3 from the array. We first use the array_search() function to find the key of 3 in the array, and if found, we use the unset() function to delete the element corresponding to that key. Finally, we use the print_r() function to print the array after deleting the element.
