Options

In this article, we will focus on the mysqli_options() function in PHP, which is used to set extra connect options.

Introduction to the mysqli_options() function

The mysqli_options() function is a built-in function in PHP that is used to set extra connect options for the MySQLi connection. It allows you to configure the behavior of the MySQLi extension.

How to use the mysqli_options() function

Using the mysqli_options() function is straightforward. Here's an example:

<?php
$mysqli = mysqli_init();

/* set the SSL key */
mysqli_options($mysqli, MYSQLI_OPT_SSL_KEY, "/path/to/client-key.pem");

/* set the SSL cert */
mysqli_options($mysqli, MYSQLI_OPT_SSL_CERT, "/path/to/client-cert.pem");

/* set the SSL CA */
mysqli_options($mysqli, MYSQLI_OPT_SSL_CA, "/path/to/ca-cert.pem");

/* connect to the database using SSL */
mysqli_ssl_set($mysqli, NULL, NULL, "/path/to/ca-cert.pem", NULL, NULL);

mysqli_real_connect($mysqli, "localhost", "username", "password", "database");
?>

In this example, we first initialize a new MySQLi object using the mysqli_init() function. We then set the SSL key, SSL cert, and SSL CA options using the mysqli_options() function. Finally, we connect to the database using SSL using the mysqli_ssl_set() and mysqli_real_connect() functions.

Conclusion

In conclusion, the mysqli_options() function is a powerful tool for setting extra connect options for the MySQLi extension. By understanding how to use the function, you can configure the behavior of the MySQLi extension to suit your specific needs.
