Replace string in an array with PHP

Why not just use str_replace without a loop?

$array = array('foobar', 'foobaz');
$out = str_replace('foo', 'hello', $array);

$array = array_map(
    function($str) {
        return str_replace('foo', 'bar', $str);
    },
    $array
);

But array_map is just a hidden loop. Why not use a real one?

foreach ($array as &$str) {
    $str = str_replace('foo', 'bar', $str);
}

That's much easier.

This is a very good idea that I found and used successfully:

function str_replace_json($search, $replace, $subject) 
{
    return json_decode(str_replace($search, $replace, json_encode($subject)), true);
}

It is good also for multidimensional arrays.

If you change the "true" to "false" then it will return an object instead of an associative array.
