So, i made some sorting algorithm based on sorting alphabetically but symbols first in line, numbers second and letters last. I have some arrays with some numbers which stand for item ids registered in my plugin, i set the arrays based on some conditions and then introduce the array into the function which sorts the array. At the start of the function i checked what is in that array and i see that everything (for a specific number of items representing the items in the field) and see that everything is empty, why?

In the first lines of the function 'SortItemArray' you can see that i checked the array for its item ids and in 'InitSort' that i sorted the arrays (2 arrays with 3 dimensions) in 3 for-loops (no the best idea, it could be easier in 2 but still not the problem).

PHP Code:

SortItemArray( const Sort: mtd, const SortDir: dir, const Category, array[ ] )
{
    server_print("[Buymenu] items in array to sort for category %s", g_CategName[Category]);

    for(new h = 0; h < g_iCategItems[Category]; h++)
        server_print("[Buymenu] %i", array[h]);

    if(g_iCategItems[Category] <= 1)
    {
        server_print("[Buymenu] Not enough items to sort.");
        return;
    }

    new i, j, d;

    if ( mtd == Sort_Name )
    {
        new szName[ 30 ], szName2[ 30 ];

        for ( i = 0; i < g_iCategItems[Category]; i++ )
        {
            ArrayGetString( g_ItemData[ IRD_Name ], array[ i ], szName2, charsmax( szName2 ) );

            for ( d = 0; d < sizeof g_szMenuCodes; d++ )
            {
                if ( contain( szName, g_szMenuCodes[ d ] ) )
                    replace_all( szName, charsmax( szName ), g_szMenuCodes[ d ], "");
            }

            for ( j = i+1; j < g_iCategItems[Category]; j++ )
            {
                ArrayGetString( g_ItemData[ IRD_Name ], array[ j ], szName2, charsmax( szName2 ) );

                for ( d = 0; d < sizeof g_szMenuCodes; d++ )
                {
                    if ( contain( szName2, g_szMenuCodes[ d ] ) )
                        replace_all( szName2, charsmax( szName2 ), g_szMenuCodes[ d ], "");
                }

                if ( CompareStrings( szName2, szName, dir ) > 0 )
                {
                   inverse_values( array[ i ], array[ j ] );
                }
            }
        }
    }
    else if ( mtd == Sort_Cost )
    {
        server_print("[Buymenu] Sorting by Cost:");
        new iCost[ 2 ];
        new szSysName[2][20];

        for ( i = 0; i < g_iCategItems[Category]; i++)
        {
            for ( j = i+1; j < g_iCategItems[Category]; j++ )
            {
                iCost[ 0 ] = ArrayGetCell( g_ItemData[ IRD_Cost ], array[ i ] );
                iCost[ 1 ] = ArrayGetCell( g_ItemData[ IRD_Cost ], array[ j ] );

                ArrayGetString( g_ItemData[ IRD_SystemName ], array[i], szSysName[0], charsmax(szSysName[]) );
                ArrayGetString( g_ItemData[ IRD_SystemName ], array[i], szSysName[1], charsmax(szSysName[]) );

                server_print("[Buymenu] %s vs %s", szSysName[0], szSysName[1]);

                if ( ( iCost[ 0 ] > iCost[ 1 ] && dir == SRDir_Ascendent ) ||
                    ( iCost[ 0 ] < iCost[ 1 ] && dir == SRDir_Descendent ) )
                {
                    inverse_values( array[ i ], array[ j ] );
                }

                server_print("[Buymenu] Next: ^n^n");
            }
        }
    }
}

InitSort( )
{
    new szSysName[20];
    for ( new i = 0; i < CATEGORIES; i++ )
    {
        for ( new SortDir:x = SortDir:0; x < SortDir; x++ )
        {
            for ( new z = 0; z < g_iItems; z++ )
            {
                if ( ArrayGetCell( g_ItemData[ IRD_Category ], z ) != i )
                    continue;

                ArrayGetString( g_ItemData[ IRD_SystemName ], z, szSysName, charsmax(szSysName) );

                server_print("[Buymenu] %s is part of %s (Id: %i)", szSysName, g_CategName[i], z);

                g_iSortedItemsCost[ i ][ x ][ z ] = z;
                g_iSortedItemsName[ i ][ x ][ z ] = z;
            }

            SortItemArray( Sort_Cost, x, i, g_iSortedItemsCost[ i ][ x ] );
            SortItemArray( Sort_Name, x, i, g_iSortedItemsName[ i ][ x ] );
        }
    }

    for ( new i = 0; i < CATEGORIES; i++ )
    {
        for ( new z = 0; z < g_iCategItems[i]; z++ )
        {
            ArrayGetString( g_ItemData[ IRD_SystemName ], g_iSortedItemsCost[i][SRDir_Ascendent][z], szSysName, charsmax(szSysName) );

            server_print("[Buymenu] Category %s by Cost: %i. %s", g_CategName[i], z, szSysName);
        }
    }
} 


Solved
I was setting the same cell in the third dimension.
