Very simple solution for changing the key of an associative array, of course it will fail in a lot
of scenarios, but will do the trick in simple arrays:
<?php
function replace_key(&$input, $from_key, $to_key)
{
$input = unserialize(str_replace(':"'.$from_key.'";',
':"'.$to_key.'";',serialize($input)));
}
$array =array("a"=>1, "B"=>2, "c"=>3);
replace_key($array, "B", "b");
print_r($array);
?>
Output:
Array
(
[a] => 1
[b] => 2
[c] => 3
)
