Copy paste code,

<?php
$rt=Array(Array('a','a','b','b','c','c'));
$out=array_count_values( $rt[0]);
print_r($out) ;
?>

output

Array
(
 [a] => 2
 [b] => 2
 [c] => 2
)

Use this :

array_count_values(array)

Ex:

<?php
$a=array("Cat","Dog","Horse","Dog");
print_r(array_count_values($a));
?>

output:

Array ( [Cat] => 1 [Dog] => 2 [Horse] => 1 )
