Removing Duplicate Entries From An Array

[digz81]

Hello again!

The problem I'm trying to solve sounds simple enough, but I can't seem to make it work.

[codebox]// This script is supposed to take an array provided
// and remove any duplicate items within the array
//
global proc string[] dupeClean(string $list[])
{
string $compare[] ={};
string $finalList[] ={};
$list = sort($list);
$compare= $list;
for ($i=0; $i<size($list);$i++){
for($x=0;$x<size($compare);$x++){
if ($i != $x){
if($list[$i] == $compare[$x]){
//print($dupe + "This is a dupe");
}else{
$finalList[size($finalList)] = $compare[$x];
}
}
}
}
return $finalList;
}[/codebox]

It doesn't seem to work.
Iv'e been going at it all night and just gave up.
Is there an easier way of doing this?
Am I generating the output array correctly?
can someone point me out in the right direction.

Any and all help is greatly appreciated.

Ouch, this was a serious case of RTFM.

string[] stringArrayRemoveDuplicates(string[] $list)

Thanks, anywayz.

BUT HOW WOULD U DO FOR INT OR FLOAT ARRAY ???

[trevor-van-hoof]

global proc int[] removeDuplicateIntegers(int $array[])
{
    int $index = 0;
    int $newarray[];
    for( $i = 0 ; $i < size($array) ; $i++ )
    {
        $entry = true;
        for( $j = 0 ; $j < $i ; $j++ )
        {
            if( $array[$i] == $array[$j] ) //duplicate
                $entry = false;
        }
        if( $entry == true )
        {
            $newarray[$index] = $array[$i];
            $index++;
        }
    }
    return $newarray;
}
global proc float[] removeDuplicateFloats(float $array[])
{
    int $index = 0;
    float $newarray[];
    for( $i = 0 ; $i < size($array) ; $i++ )
    {
        $entry = true;
        for( $j = 0 ; $j < $i ; $j++ )
        {
            if( $array[$i] == $array[$j] ) //duplicate
                $entry = false;
        }
        if( $entry == true )
        {
            $newarray[$index] = $array[$i];
            $index++;
        }
    }
    return $newarray;
}
int $arrayi[] = {0,1,1,0,2,4,1,6};
float $arrayf[] = {0.0,0.1,0.1,0.0,0.2,0.4,0.1,0.6};
print(removeDuplicateIntegers($arrayi));
print(removeDuplicateFloats($arrayf));

This loops through the array and matches the entry with all previous entries with a double for loop. If an entry is the same as any previous it does not get entered into the output array. Be aware though that entering the new array straight into the old array variable it is very well possible that the old array is longer than the new one, any entries that are beyond the new array are then not replaced with blank fields resulting in the function defying its purpose and the creation of new duplicate entries.
