PHP MySQL Database


PHP MySQL Database

In the previous tutorial, we create PHP Connection To MySQL. For this follow-up tutorial, I decided to make a tutorial on How To Create MySQL Database. For creating a database, it will consist one or more tables in one database. We create a database and name it as “myDatabase”.

Creating MySQL Database Using MySQLi and PDO

Example database name "myDatabase".

Example MySQLi Object-Oriented

  1. <?php
  2. $servername = "localhost";
  3. $username = "username";
  4. $password = "password";
  5.  
  6. // Create connection
  7. $conn = new mysqli($servername, $username, $password);
  8. // Check connection
  9. if ($conn->connect_error) {
  10. die("Connection Error. Check your syntax." . $conn->connect_error);
  11. }
  12.  
  13. // Create database
  14. $sql = "CREATE DATABASE myDatabase";
  15. if ($conn->query($sql) === TRUE) {
  16. echo "Successfully Created The Database";
  17. } else {
  18. echo "Error creating database. Check the Syntax." . $conn->error;
  19. }
  20.  
  21. $conn->close();
  22. ?>

Example database name "myDatabase".

Example MySQLi Procedural

  1. <?php
  2. $servername = "localhost";
  3. $username = "username";
  4. $password = "password";
  5.  
  6. // Create connection
  7. $conn = mysqli_connect($servername, $username, $password);
  8. // Check connection
  9. if (!$conn) {
  10. die("Connection Error. Check your syntax." . mysqli_connect_error());
  11. }
  12.  
  13. // Create database
  14. $sql = "CREATE DATABASE myDatabase";
  15. if (mysqli_query($conn, $sql)) {
  16. echo "Successfully Created The Database";
  17. } else {
  18. echo "Error creating database. Check the Syntax." . mysqli_error($conn);
  19. }
  20.  
  21. mysqli_close($conn);
  22. ?>

Example database name "myDatabase".

Example PDO (PHP Data Objects)

  1. <?php
  2. $servername = "localhost";
  3. $username = "username";
  4. $password = "password";
  5.  
  6. try {
  7. $conn = new PDO("mysql:host=$servername;dbname=myDatabase", $username, $password);
  8. // set the PDO error mode to exception
  9. $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
  10. $sql = "CREATE DATABASE myDatabase";
  11. // use exec() because no results are returned
  12. $conn->exec($sql);
  13. echo "Successfully Created The Database<br>";
  14. }
  15. catch(PDOException $e)
  16. {
  17. echo $sql . "<br>" . $e->getMessage();
  18. }
  19.  
  20. $conn = null;
  21. ?>

I use PHPMyAdmin to create a database in MySQL. After creating my database in PHPMyAdmin, this is my query using PDO in shortcodes.

  1. <?php
  2. $conn = new PDO("mysql:host=localhost;dbname=myDatabase", 'username', 'password');
  3. ?>
