This is a fast solution to remove duplicate values from an array when it contains only strings or
only integers:
<?php
$array = array(
0 => 'Yellow',
1 => 'Green',
2 => 'Yellow',
3 => 'Blue',
4 => 'Yellow',
);
$uniq = array_keys(array_flip($array));
var_export($uniq);
/* Output:
array (
0 => 'Yellow',
1 => 'Green',
2 => 'Blue',
)
*/
?>
