[RESOLVED] Newbie Help

[Energy48]

I am very very new to PHP so please bear with my naivety,

I am doing an array_intersect and want to use the results to create another table; the following is an example of where I am now and I am stuck.

<?php

$array_1 = array(1,2,3,4,5,6,7);
$array_2 = array(3,8,0,9,7);

$common = array_intersect($array_1, $array_2);

foreach ($common as $value) {
	echo $value;
   } 
?>

The answer is 37

My problem is I am looking for a way to COUNT/ADD the echoed answer instead of the actual 37 which is the intersection. What I mean is, instead of 37, I want to write the code to give me 2 which is the count of the 3 and 7. That is "2" being the number of times of the intersect. If it is 0 then 0 is the number of times of intersection and so on and so forth.

Does anyone who how I can do this please

This should do it:

<?php

$array_1 = array(1,2,3,4,5,6,7);
$array_2 = array(3,8,0,9,7);

$common = array_intersect($array_1, $array_2);
$i = 0;

foreach ($common as $value) {
$i++;
} 
echo "Count: " . $i;
?>
