11.2. The syntax of SQL code

Aiming at making PHP-Nuke compatible with more databases, the SQL syntax has been transformed to functions, in order to achieve a standard syntax that is independent of the database used. For convenience, let us recall the file sql_layer.php in a somewhat cleaned-up version:

sql_connect($host, $user, $password, $db) 
sql_logout($id) 
sql_query($query, $id) 
sql_num_rows($res) 
sql_fetch_row(&$res, $nr) 
sql_fetch_array(&$res, $nr) 
sql_fetch_object(&$res, $nr) 
sql_free_result($res)

: Log into the DB.
: Disconnect from the DB.
: Query.
: Number of Rows.
: Fetch Rows.
: Fetch Array.
: Fetch Object.
: Free Result.

With this syntax you will be able to render all the modifications, blocks or modules you create compatible to all the databases supported by PHP-Nuke, which are:

MySQL
mSQL
PostgreSQL
PostgreSQL_local
ODBC
ODBC_Adabas
Interbase
Sybase
