array_count_values() does something like this. It groups together
values and tells you how many times they occur in an array...
example
------------------------
$array = array(
array("foo","bar","rex"),
array("foo","bar","zip"),
array("foo","bar","zoo"),
array("foo","bar","rex"));
/* put all elements into one array */
foreach($array as $val) { $temp_array[] = $val[2];}
/* count values. see php.net/array_count_values */
$count = array_count_values($temp_array);
print"<pre>";
print_r($count);
print"</pre>";
--------------------
this produces ...
Array
(
[rex] => 2
[zip] => 1
[zoo] => 1
)
