PHP array delete by value (not key)?

Question

I have a PHP array as follows: $messages = [312, 401, 1599, 3, ...]; I want to delete the element containing the value `$del_val` (for example, `$del_val=401`), but I don't know its key. This might help: **each value can only be there once**. I'm looking for the simplest function to perform this task please.

Answer 1

You can use a function in php called array_filter to remove an array element by value

$del_val=401;

$messages = [312, 401, 1599, 3, ...];

$array = array_filter($array, function($v) {

return $v !== $del_val;

});

I hope this helps
