Question

If I know the query only returns one row, and more specefically, in this case one value,

$full_name = database::query("SELECT concat (fname, ' ', lname) from cr WHERE email='$email'");

how do I get that value into a single variable. Database::query returns the value form mysql_query. The query above insert “Resource ID 4” in to mysql table.

Answer 1

I don’t know about database::query(), but mysql_query() does indeed return a resource.

Once you have that resource, you must fetch your data from it, using, for example, mysql_fetch_array() :

$data = mysql_fetch_array($full_name);

Note that there are several mysql_fetch_* function, depending on what kind of result your want (array, object, …) :

• mysql_fetch_row()
• mysql_fetch_object()
• mysql_fetch_assoc()
