First you must know which part of the associative array you're going to use as haystack in in_array function. Then you can use in_array without additional code.

Example with values :

 "apple", 2 => "banana", 3 => "lemon", 4 => "pear");
$haystack = array_values($assoc);
echo "
" . print_r($assoc, true) . "
";

$needle = 'banana';
$find = (in_array($needle, $haystack)) ? 'TRUE' : 'FALSE';
echo "
$needle : $find
";

$needle = 'cherry';
$find = (in_array($needle, $haystack)) ? 'TRUE' : 'FALSE';
echo "
$needle : $find
";
?>

Results in :

Array ( [1] => apple [2] => banana [3] => lemon [4] => pear )

banana : TRUE

cherry : FALSE
