Answer 1

Actually I found something that might work for you, have a look at this-

http://php.net/manual/en/function.key.php

This page says that the code below,

 'apple',
    'fruit2' => 'orange',
    'fruit3' => 'grape',
    'fruit4' => 'apple',
    'fruit5' => 'apple');

// this cycle echoes all associative array
// key where value equals "apple"
while ($fruit_name = current($array)) {
    if ($fruit_name == 'apple') {
        echo key($array).'
';
    }
    next($array);
}
?>

would give you the output,

fruit1
fruit4
fruit5

As simple as that.
