php remove duplicates from array

Question

I was wondering if anyone could help me out, I\'m trying to find a script that will check my entire array and remove any duplicates if required, then spit out the array in t

Answer 1

Try this, it works with large arrays:

$original = array('one', 'two', 'three', 'four', 'five', 'two', 'four');
$filtered = array();
foreach ($original as $key => $value){
    if(in_array($value, $filtered)){
        continue;
    }
    array_push($filtered, $value);
}

print_r($filtered);

Outputs:

Array
(
    [0] => one
    [1] => two
    [2] => three
    [3] => four
    [4] => five
)
