MySQLiStmt

MySQLiStmt is a class in PHP that provides a way to execute prepared statements using the MySQLi extension. Prepared statements are a feature of SQL that allows for the execution of a SQL statement multiple times with high efficiency. They are particularly useful for preventing SQL injection attacks by separating SQL logic from data.

To use MySQLiStmt, you first need to create a MySQLi object to establish a connection to the database. Then, you can prepare a SQL statement using the prepare method of the MySQLi object, which returns a MySQLiStmt object. The SQL statement can contain placeholders for parameters, which are represented by question marks (?) or named parameters (e.g., :name).

Once you have a MySQLiStmt object, you can bind values to the parameters using the bind_param method. This method takes a string that specifies the types of the parameters (e.g., "s" for string, "i" for integer) and the values to bind. After binding the parameters, you can execute the statement using the execute method.

The MySQLiStmt class also provides methods for fetching results, such as fetch, fetch_assoc, and fetch_all. These methods allow you to retrieve the results of the query in various formats, such as an associative array or a numeric array.

In summary, MySQLiStmt is a powerful tool for executing prepared statements in PHP using the MySQLi extension. It provides a secure and efficient way to interact with a MySQL database, helping to prevent SQL injection attacks and improve performance.
