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 before establishing a connection.

How to use the mysqli_options() function

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

How to use the mysqli_options() function?

<?php
$mysqli = mysqli_init();

/* Set connection timeout to 10 seconds */
mysqli_options($mysqli, MYSQLI_OPT_CONNECT_TIMEOUT, 10);

/* Enable local infile loading */
mysqli_options($mysqli, MYSQLI_OPT_LOCAL_INFILE, 1);

/* Connect to the database */
if (!mysqli_real_connect($mysqli, "localhost", "username", "password", "database")) {
    die("Connection failed: " . mysqli_connect_error());
}

echo "Connected successfully";
?>

In this example, we first initialize a new MySQLi object using the mysqli_init() function. We then configure connection parameters like the timeout and local file access using the mysqli_options() function. Finally, we connect to the database using mysqli_real_connect() and verify the connection. Note that SSL configuration (key, certificate, and CA paths) is handled separately by the mysqli_ssl_set() function, not mysqli_options().

Conclusion

In conclusion, the mysqli_options() function is a useful tool for configuring connection parameters like timeouts and local file access for the MySQLi extension. By understanding how to use the function, you can tailor the connection behavior to your specific needs.
