Init

In this article, we will focus on the mysqli_init() function in PHP, which is used to initialize a MySQLi object. We will provide you with an overview of the function, how it works, and examples of its use.

Introduction to the mysqli_init() function

The mysqli_init() function is a built-in function in PHP that is used to initialize a MySQLi object. This function is useful when you need to create a new MySQLi object and set specific options for it.

How to use the mysqli_init() function

Using the mysqli_init() function is very simple. You just need to call the function to create a new MySQLi object. Here is an example:

<?php
$mysqli = mysqli_init();

mysqli_options($mysqli, MYSQLI_INIT_COMMAND, "SET NAMES 'utf8'");

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

if (mysqli_connect_errno()) {
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

mysqli_close($mysqli);
?>

In this example, we call the mysqli_init() function to create a new MySQLi object. We then set a specific option for the MySQLi object using the mysqli_options() function. We then call the mysqli_real_connect() function to connect to a MySQL database with a username and password. We then check if the connection was successful using the mysqli_connect_errno() function and output an error message if it failed. We then close the MySQLi connection using the mysqli_close() function.

Conclusion

In conclusion, the mysqli_init() function is a useful tool for initializing a MySQLi object with specific options. By understanding how to use the function, you can take advantage of this feature to create powerful and flexible MySQLi queries.
