PHP's array_search() does this:
Searches the array for a given value and returns the corresponding key if successful
I would like a function that does the exact opposite, that is, searches the array for a given key and returns the corresponding value if successful.
Is this available at all in PHP 5? If not, what solution would you suggest?

I am confused. Would $array[$key] not work?

You can just use square bracket syntax, as follows:
$arr = array("key" => "value");
$v = $arr["key"]; // returns "value"
