Find specific value in an array

Question

There is an array:

$arr = array(
        'AA' => 90,
        'AB' => 150,
        'BC' => 100,
        'CD' => 60
);

and a string:

$val = 'CD'

Is there any quick way (without FOR loop) to define the numeric value corresponding to $val? In this example the result must be 60.

are you asking for `$arr[$val]`? – Erik Sep 11 '12 at 15:34 — Erik, Sep 11 '12 at 15:34
`$value = isset($arr[$val]) ? $arr[$val] : null` ? – tigrang Sep 11 '12 at 15:35 — tigrang, Sep 11 '12 at 15:35

You literally just need $arr[$val].

echo $arr[$val]; will output 60.
