Question

I want to remove some duplicate values on an array, but there is a condition that the script has to ignore the array that contains a specific word.

Below code is adapted from PHP: in_array.

$array = array( 'STK0000100001',
                'STK0000100002',
                'STK0000100001',           //--> This should be remove
                'STK0000100001-XXXX',      //--> This should be ignored
                'STK0000100001-XXXX' );    //--> This should be ignored

$ignore_values = array('-XXXX');

if(make_unique($array, $ignore_values) > 0) {
    //ERROR HERE
}

The function to make the array unique is:

function make_unique($array, $ignore) {
    $i = 0;
    while($values = each($array))  {
        if(!in_array($values[1], $ignore)) {
            $dupes = array_keys($array, $values[1]);
            unset($dupes[0]);
            foreach($dupes as $rmv) {
                $i++;
            }            
        }
    }
    return $i;
}

I have tried to use if(!in_array(str_split($values[1]), $ignore)) ... but it just the same.

The array should become like:

STK0000100001
STK0000100002
STK0000100001-XXXX
STK0000100001-XXXX

How to do that?

Try this one, just remove the print_r(); inside the function when using in production

if(make_unique($array, $ignore_values) > 0) {
    //ERROR HERE
}

function make_unique($array, $ignore)  {
    $array_hold = $array;
    $ignore_val = array();
    $i = 0;
    foreach($array as $arr) {
        foreach($ignore as $ign) {
            if(strpos($arr, $ign)) { 
                 array_push( $ignore_val, $arr);
                 unset($array_hold[$i]);
                 break;
            }
        }
        $i++;
    }
    $unique_one = (array_unique($array_hold));
    $unique_one = array_merge($unique_one,$ignore_val);
    print_r($unique_one);

    return count($array) - count($unique_one);
}
