How does CodeIgniter handle prepared statements?

Using Prepared Statements in CodeIgniter

In CodeIgniter, prepared statements are not natively supported. Instead, query bindings with unnamed placeholders are used to simplify query execution. When attempting to use prepared statements, represented by :placeholders, users may encounter issues.

To resolve this discrepancy, it's important to understand that CodeIgniter's Database class replaces question mark placeholders with data from an array. This means that query bindings are used instead of true prepared statements.

For instance, the following code snippet demonstrates query binding in CodeIgniter:

<code class="php">$sql = "SELECT * FROM some_table WHERE id = ? AND status = ? AND author = ?";
$this->db->query($sql, array(3, 'live', 'Rick'));</code>

In this example, the question marks are automatically replaced with the values in the array passed to the query function.

While CodeIgniter does not support traditional prepared statements, the concept of query bindings serves a similar purpose by simplifying the query construction process. By using query bindings with unnamed placeholders, developers can achieve comparable results without the need for separate prepare and execute functions.
