Let’s look into each of them one by one: 1. Once this is achieved, we can use different procedures to establish a connection with the database. When you change the values in one file, it automatically changes all values in each and every file and saves you the efforts of making changes in every file. This is also useful when you need to transfer your entire project from one system to another.

We can just use the PHP file connection name along with the include function and insert the data instead of rewriting the code each time. This saves time to write code every time you want to insert data and information from the database and insert this data in multiple files. First of all, we have to create a separate connection file. This command is used to set up a connection between the database and PHP. Mainly, we will be using mysqli_connect in all three procedures. To start with any of these, it is required to know some important details such as your database system’s server address, username, database name, and password. PHP and MySQL are some of the most common stacks for web development. Prepared statements are principal in web security which are allowed in both PDO and MySQLi. MySQLi also provides a procedural programming interface along with an object-oriented one. Working with MySQLi requires MySQLi to be enabled on PHP. But in the case of MySQLi, we need to write the entire code and query to switch databases. So, if one is switching databases, PDO might come in handy as it only requires changing a few connections. The MySQLi extension can be used only with MySQL databases, whereas PDO can be used to connect with 12 different variety of database systems. The 5 th version of PHP and newer versions can work with below:Īny one of the above can be used according to their own supremacy and one’s needs. But this extension was derogated in 2012. PHP versions below 5 use MySQL extension. SQL command for tables is a simple query “” with syntax as below. This newly created database will be empty, waiting for the inclusion of tables with data. Although “” is non-mandatory, it is a good practice.

On the other hand, if there is no such conflict of database names, the below command will be executing and creating a database.

If yes, the command will not execute the creation of the database. What this query does is it checks whether any existing database has the same name. This can be done by executing the command CREATE DATABASE movies Īdding more parameters and avoiding confusion between existing databases on a single MySQL server can use the command “”.
