Option 1:
new data[65] //steam-id and name can max be 32 characters
Then store the ID in data[0], steam-id from 1-33 and name from 34-65.
Option 2:
Build a enum, which is easier to handle and to keep the overview:
PHP Code:
new enum _:data_structure{
id,
steam[32],
name[32] }
// Build variable
new data[data_structure];
//Now you can access the fields in your data-variable by their names
data[id] = id;
copy(data[steam], steam-id, 31);
copy(data[name], name, 31);
