How to find a value in an array and remove it by using PHP array functions?

To search an element in an array, you can use array_search function and to remove an element from an array you can use unset function. Ex:

<?php
$hackers = array ('Alan Kay', 'Peter Norvig', 'Linus Trovalds', 'Larry Page');

print_r($hackers);

// Search
$pos = array_search('Linus Trovalds', $hackers);

echo 'Linus Trovalds found at: ' . $pos;

// Remove from array
unset($hackers[$pos]);

print_r($hackers);

You can refer: https://www.php.net/manual/en/ref.array.php for more array related functions.

<?php
$my_array = array('sheldon', 'leonard', 'howard', 'penny');
$to_remove = array('howard');
$result = array_diff($my_array, $to_remove);
?>
