Question

How can I convert all values in an array to lowercase in PHP?

Something like array_change_key_case?

Answer 1

`$Color = array('A' => 'Blue', 'B' => 'Green', 'c' => 'Red');

$strtolower = array_map('strtolower', $Color);

$strtoupper = array_map('strtoupper', $Color);

print_r($strtolower); print_r($strtoupper);`
