The sql_free() function is used to release an SQL resource opened using a call to the sql_select() function. Ideally this function ought to be called after finishing using each resource. It accept 3 parameters: -# $res is the resource for a selection, -# $serveur, -# $option. The sql_free() function is therefore used as shown below:
$res = sql_select('column', 'table');
// operations using the sql_fetch($res) and similar functions ...
// then close the resource
Note that the API functions call this function automatically. This is the case for: -* sql_fetsel (and sql_getfetsel), -* sql_fetch_all (and sql_allfetsel), -* sql_in_select.
