Hey, whats the best way to find all unique entries in an array?
Is there maybe a function thats suitable for this?

Thanks in advance

Took this as a challenge and made this out! Not sure if this is the best way or not. Untested.

PHP Code:

int[] GetUniqueIndexesFromIntegerArray(int[] array, int maxsize)
{
    int count = 0;
    int[] indexes = new int[maxsize+1];
    for(int i = 0; i < maxsize; i++)
    {
        for(int j = 0; j < maxsize; j++)
        {
            if(i == j)
            {
                if(j == maxsize-1)
                {
                    indexes[count++] = i;
                    break;
                }
                continue;
            }
            else if(array[i] == array[j])
            {
                break;
            }
            else if(j == maxsize-1)
            {
                indexes[count++] = i;
            }
        }
    }
    return indexes;
}

int[] GetUniqueIndexesFromStringArray(char[][] strings, int maxsize)
{
    int count = 0;
    int[] indexes = new int[maxsize+1];
    for(int i = 0; i < maxsize; i++)
    {
        for(int j = 0; j < maxsize; j++)
        {
            if(i == j)
            {
                if(j == maxsize-1)
                {
                    indexes[count++] = i;
                    break;
                }
                continue;
            }
            else if(strcmp(strings[i], strings[j]) == 0) // case sensitive.
            {
                break;
            }
            else if(j == maxsize-1)
            {
                indexes[count++] = i;
            }
        }
    }
    return indexes;
}
