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) 

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
