Fatal Error Call To Undefined Function Mysqli_Init In Mysqli_Driver Php

What is PHP Mysqli_Driver?

PHP Mysqli_Driver is a MySQL driver for PHP. This driver facilitates interaction between a PHP application and a MariaDB or MySQL server. With the Mysqli_Driver class one can connect, prepare, query and close a connection to a MariaDB/MySQL database. It is to be noted that the connection will be closed automatically when the script ends.

It is important to note that when we call Mysqli_Init, a new connection to the MariaDB or MySQL server will be initialized. The Mysqli_Driver class also provides functions like Mysqli_Connect, Mysqli_Prepare, Mysqli_Query, and Mysqli_Close. With the help of these functions, we can manipulate data and store the result set in a MySQL database.

Error Message of Mysqli_Init

The error message that one comes across when there is a problem with Mysqli_Init is, “Fatal Error Call to undefined function Mysqli_Init in Mysqli_Driver PHP”, which essentially means that the required methods are not available for the given driver.

The main cause of this message is that the Mysqli_Driver class is missing from the include path. In this case, one has to include the relevant driver package in the include path. Another potential cause of the problem is that a different version of the driver may be installed. This can lead to compatibility issues and throw the aforementioned error message.

What is the Solution?

To solve this problem, one must start by checking if the Mysqli_Driver class is present in the include path. If the class is missing, one can use the require_once command to include the driver into the include path. Additionally, one can ensure that the correct version of the driver is installed and confirmed that the driver is compatible with the MariaDB or MySQL server.

Faulty Configuration

A few settings may lead to an error while calling the Mysqli_Init function. For instance, if the incorrect or outdated configuration settings are used, this may throw a fatal error. Additionally, outdated versions of PHP may cause compatibility issues, as the OOP design may have changed between PHP versions. The best approach is to check the version of PHP and make sure that the version of the driver being used is compatible with the version of PHP being used.

Incorrect Syntax

If the syntax of the code is incorrect, then this too can throw an error while calling the Mysqli_Init function. To avoid such mistakes, one must always use the correct syntax when coding with PHP and the Mysqli_Driver. Incorrect coding may lead to fatal errors when running the script.

Conclusion

In conclusion, one can use the Mysqli_Init command to make a connection to the MariaDB or MySQL server. However, fatal errors can occur when there is a problem with the configuration of the PHP version, Mysqli_Driver version, or a problem with the syntax of the code being used. The best approach is to check the configuration, ensure that the Mysqli_Driver class is present in the include path, and check the syntax of the code being used.
