printing the contents of a variable

[filburt1]

query() returns a handle that you can reference using fetch_row() to fetch sequential rows. query_first() just returns the first row, if any, of the query.

These two are equivalent:

PHP Code:

$foo = $DB_site->query_first("SELECT COUNT(*) FROM " . TABLE_PREFIX . "post"); 


and

PHP Code:

$result = $DB_site->query("SELECT COUNT(*) FROM " . TABLE_PREFIX . "post");
$foo = $DB_site->fetch_array($result); 


(BTW, SELECT COUNT(*) is fine if there is no WHERE clause, at least in MySQL's case)
