PHP & MySQL: Creating a Database

Updated on June 27, 2011

A database is a place where multiple tables are existed. These tables are known as objects. A database can be created easily by using PHP and MySQL. To create a database, CREATE DATABASE database_name command is used. This page describes the process of creating a database from the PHP file by using MySQL.

Creating a Database

To create a database create database command is used. The syntax of database creation is given below:

CREATE DATABASE database_name

Here, database_name = name of the database.

For executing CREATE DATABASE statement, mysql_query() function is used. mysql_query() function sends a query to MySQL connection. Without it, it's not possible to send query to MySQL connection.

Example of creating a database

Let, we want to create a database named as my_db. Now the sample code for creating the database will look like the followings:

<?php
    $my_con = mysql_connect("localhost","root","");
    
    if (!$my_con){
          die('Connection failed: ' . mysql_error());
    }

    if (mysql_query("CREATE DATABASE my_db",$my_con)){
          echo "Database created successfully...";
    }
    
    else  {
          echo "Error while creating the database: " . mysql_error();
    }

    mysql_close($my_con);
?>

After the database my_db is created successfully, Database created successfully... message will be show on your browser page.

Discussion of the above code segment

Here, $my_con variable is used to connect with MySQL. Later, CREATE DATABASE command is used to create database. If the database is created successfully, Database created successfully... message will be shown. Otherwise, Error while creating the database: message will be displayed.
