You should loop through found categories instead of all previous categories while working with large arrays (as you mentioned this is for a furniture system? fyi: not on this thread).

Sample:

PHP код:

enum e_array
{
    something_1,
    something_2,
    something_3[40],
    category[20]
};

new array[][e_array] =
{
    {0, 380, "asdfafa", "Other"},
    {0, 578, "asdfafafdsafa", "Other"},
    {0, 578, "asdfafafdxsafasfadwada", "Another"},
    {0, 578, "asdfafafdxsafasfawadaaasd", "Another"},
    {0, 578, "asdfafafdxsafasfawadaaasdfff", "Test Something"},
    {0, 578, "asdfafafdxsafasfawadaaasdffffawfwa", "Another Test"},
    {0, 578, "asdfafafdxsafasfawadaaasd", "Test"},
    {0, 578, "asdfafafdxsafasfawadaaasd", "Another"},
    {0, 380, "asdfafa", "Test"}
};

main()
{
    new categories[10][20];
    for(new i = 0, j = sizeof(array), count, bool:duplicate; i < j; i ++, duplicate = false)
    {
        for(new k = 0; categories[k][0] != EOS; k ++)
        {
            if(!strcmp(array[i][category], categories[k], false))
            {
                duplicate = true;
                break;
            }
        }

        if(!duplicate)
        {
            strcat(categories[count ++], array[i][category], 20);

            printf("%d %s", i, array[i][category]);
        }
    }
}
