$all = array
(
    0 => 307,
    1 => 157,
    2 => 234,
    3 => 200,
    4 => 322,
    5 => 324
);
$search_this = array
(
    0 => 200,
    1 => 234
);

I would like to find out if $all contains all $search_this values and return true or false. any idea please?

Look at array_intersect()

<?php
$containsSearch = count(array_intersect($search_this, $all)) == count($search_this);

I think you're looking for the intersect function

array array_intersect ( array $array1 , array $array2 [, array $ ... ] )
array_intersect() returns an array containing all the values of array1 that are 
present in all the arguments. Note that keys are preserved.
