Solved remove variable from array

hi when i have array like this:

PHP:

 ["one", "two", "three"]

how can i remove "two" when i dont know key?

or

PHP:

$array = [1, 2, 3, 4,5];
$var = rand(1, 5);

and i need to remove $var

EDIT: maybe array_search() ---> no it wont work

Try unset($var)
http://php.net/manual/de/function.unset.php

You can use differences

PHP:

<?php
$array = array("one", "two", "three");
$array = array_diff($array, array('two'));
print_r(array_values($array));
?>

In my example above $array would now be: array("one", "three");

also remember, that php counts 0,1,2 in arrays, not 1,2,3
Just in case you forgot

so what return your code? true?

or []

i used foreach

array_diff returns an array

unset($array[array_search(2, $array)]);

but it doesnt return key isn´t?

array_search gets the key.

All arrays have a key, if you don't set it's automatically set as a number. In this case:

PHP:

"one" => [0]
"two" => [1]
"three" => [2]


Sure i though array_search return position in array
