I have two arrays, I need to find out the value for each of the array which is the same.
For example,
$arr1=array("a", "b", "c");
$arr2=array("c", "d", "e");
Then c should be display. How could I do this?

$word1 =array('a', 'b','c', 'd');
$word2 =array('b', 'c', 'd', 'a');
$data = array_intersect($word1, $word2);
it will return a,b,d because that is common in both array
print_r( $data );
/* result:
Array (
[0] => a
[1] => b
[3] => d
) */

Rather than only post a block of code, please explain why this code solves the problem posed. Without an explanation, this is not an answer.
If you want to do it "manually", here is one way:
$a1 = array("a", "b", "c");
$a2 = array("c", "d", "e");
$a3 = array();
foreach($a1 as $x) foreach($a2 as $y) if($x == $y) $a3[] = $x;
print_r($a3);
// prints:
// Array
// (
// [0] => c
// )
