PHP: remove element from associative array?

Question

how would i go about removing a certain key-value pair, given the key? thanks!

Answer 1

You can use the unset

unset($array['key-here']);

Example:

$array = array("key1" => "value1", "key2" => "value2");
print_r($array);

unset($array['key1']);
print_r($array);

unset($array['key2']);
print_r($array);

Output:

Array
(
    [key1] => value1
    [key2] => value2
)
Array
(
    [key2] => value2
)
Array
(
)

Answer 2

Use unset():

unset($array['key1']);

Answer 3

Using the unset function:

unset($array['key1'])
