AmigaBlizzard and Jefff have already pointed you where your problem is.
The evSahipIsim() part is correct, your evSahip() "callback" is not.

PHP код:

forward evSahip(evID);
public evSahip(evID)
{
    new
        rows,
        fields,
        sahipIsim[24];
    cache_get_data(rows, fields, g_iHandle);
    cache_get_field_content(0, "Character", sahipIsim, g_iHandle, sizeof(sahipIsim));
    
    // strpack(HouseData[evID][houseOwner], sahipIsim, 24 char);
    // ^ you cannot magically store a string to an integer variable
    
    // do what you need with the house owner
    // stored as a string in "sahipIsim" array
    
    return 1;
}
