Number of same/equal elements in array

[Anon]

Hi!

Let's say - I have an array, which contains many names and some of them are multiple times in array. So, my problem is: how to find out, how many an element occurs in array.

Try this:

$matchCount = sizeof(array_intersect($myArray, $matchValue));

Sorry about that, accidentally submitted that in the middle of editing it.. Here's all of it.

$myArray = array ("what", "what", "do", "what");
$matchValue = "what";

$matchCount = sizeof(array_intersect ($myArray, array($matchValue)));

$matchCount will equal 3 in this example.

If it's likely you'd be wanting to do this more than once for different keys, then you could consider using array_count_values().

From the manual:
$array = array (1, "hello", 1, "world", "hello");
array_count_values ($array); // returns array (1=>2, "hello"=>2, "world"=>1)

Thank you!
