Prepared statements are an essential tool for enhancing database security and performance. However, it is important to note that CodeIgniter does not natively support prepared statements. Despite this, we can employ query bindings, a similar approach that offers substantial benefits.
CodeIgniter embraces unnamed query bindings, where question marks (?) act as placeholders within SQL queries. These placeholders are automatically replaced with values specified in an array passed to the query function.
For instance:
$sql = "SELECT * FROM tbl_user WHERE uid = ? AND activation_key = ?"; $this->db->query($sql, array($uid, $activation_key));
Although CodeIgniter lacks explicit support for named bindings (e.g., :id and :key), replacing question marks with named placeholders does not indicate the use of prepared statements. Named bindings simply provide a different syntax alternative within query bindings.
It is crucial to understand that using ? or :foo does not signify the preparation of statements. Prepared statements require two distinct function calls: prepare() and execute(), which are not supported in CodeIgniter.
Despite the absence of prepared statements, query bindings offer several advantages:
