sql_explain

The sql_explain() function is used to return an explanation of how the SQL server will process a request. This function is used by the debugger to provide information relating to the generated SQL commands.

The function accepts 3 parameters:

1. $q is the SQL query,
2. $serveur,
3. $option.

One possible usage might be:

$query = sql_get_select('column', 'table');
$explain = sql_explain($query);
