Search and replace inside an associative array

Question

I need to search and replace inside an associative array.

ex:

$user = \"user1\"; // I\'ve updated this

$myarray = array(\"user1\" => \"search1\",

Since the post was updated, and I have had chance to get some sleep, I realized my answer was stupid. If you have a given key and you need to change it's value, why iterate over the whole array?

$user    = 'user1';
$search  = 'search1';
$replace = 'search4';
$array   = array('user1' => 'search1', 'user2' => 'search2');

if (isset($array[$user]) && $search === $array[$user]) $array[$user] = $replace;

Similar to @Joseph's method (pretty much the same), but with a few tweaks:

$user = 'user1';
$array = array("user1" => "search1", "user2" => "search2" );

foreach($array as $key => &$value) {
    if ($key === $user) {
        $value = 'search4';
        break; // Stop iterating after key has been found
    }
}

Passing by reference is a nicer way to edit inside foreach, and is arguably quicker.
