PHP delete an element from an array



If you want to delete just one array element you can use \unset() or alternative \array_splice(). How can you remove an element from an array when you know the elements name? for example:


Example: delete plums
<?php
$array = array('pears', 'apple', 'orange', 'strawberry', 'plums', 'kiwi');
?>

how to solve it?
Use array_search to get the key and remove it with unset if found:

Example: delete plums
<?php

$array = array('pears', 'apple', 'orange', 'strawberry', 'plums', 'kiwi');
if (($key = array_search('plums', $array)) !== false) {
unset($array[$key]);
}
echo $key;
?>



If there can be multiple items with the same value, you can use array_keys to get the keys to all items:

Example: delete plums
<?php
$array = array('pears', 'apple', 'orange', 'strawberry', 'plums', 'kiwi');
foreach (array_keys($array, 'plums') as $key) {
unset($array[$key]);
}
echo $key;
?>
