When creating dynamic webpages, connecting a PHP application to a MySQL database is a vital step. PDO (PHP Data Objects) and MySQLi (MySQL Improved Extension) are two well-liked ways that PHP provides for creating this connection.<\/p>\n

Method to Connect a MySQL Database to PHP Using MySQLi and PDO<\/strong><\/h2>\n

Let\u2019s explore the two methods:<\/p>\n

Method 1: Connect Using MySQLi<\/strong><\/h4>\n

MySQLi supports both object-oriented and procedural approaches.<\/p>\n

    \n
  1. Object-Oriented Example<\/strong>\n
    <?php\r\n\r\n$servername = \u201clocalhost\u201d;\r\n\r\n$username\u00a0\u00a0 = \u201croot\u201d;\r\n\r\n$password\u00a0\u00a0 = \u201c\u201d;\r\n\r\n$database\u00a0\u00a0 = \u201ctest_db\u201d;\r\n\r\n\/\/ Create connection\r\n\r\n$conn = new mysqli($servername, $username, $password, $database);\r\n\r\n\/\/ Check connection\r\n\r\nif ($conn->connect_error) {\r\n\r\n\u00a0 \u00a0 \u00a0die(\u201cConnection failed: \u201d . $conn->connect_error);\r\n\r\n}\r\n\r\necho \u201cConnected successfully (MySQLi - OOP)\u201d;\r\n\r\n?><\/pre>\n<\/li>\n<\/ol>\n
      \n
    1. Procedural Example<\/strong>\n
      <?php\r\n\r\n$servername = \u201clocalhost\u201d;\r\n\r\n$username\u00a0\u00a0 = \u201croot\u201d;\r\n\r\n$password\u00a0\u00a0 = \u201c\u201d;\r\n\r\n$database\u00a0\u00a0 = \u201ctest_db\u201d;\r\n\r\n\/\/ Create connection\r\n\r\n$conn = mysqli_connect($servername, $username, $password, $database);\r\n\r\n\/\/ Check connection\r\n\r\nif (!$conn) {\r\n\r\n\u00a0 \u00a0 die(\u201cConnection failed: \u201d . mysqli_connect_error());\r\n\r\n}\r\n\r\necho \u201cConnected successfully (MySQLi - Procedural)\u201d;\r\n\r\n?><\/pre>\n<\/li>\n<\/ol>\n
      Method 2: Connect Using PDO<\/strong><\/h4>\n
      PDO is more flexible as it supports multiple databases (MySQL, PostgreSQL, SQLite, etc.), making it a preferred option for larger projects.<\/p>\n
      <?php\r\n$servername = \u201clocalhost\u201d;\r\n$username\u00a0\u00a0 = \u201croot\u201d;\r\n$password\u00a0\u00a0 = \u201c\u201d;\r\n$database\u00a0\u00a0 = \u201ctest_db\u201d;\r\n\r\ntry {\r\n$conn = new PDO(\u201cmysql:host=$servername;dbname=$database\u201d, $username, $password);\r\n\r\n\/\/ Set PDO error mode to exception\r\n$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);\r\necho \u201cConnected successfully (PDO)\u201d;\r\n} catch(PDOException $e) {\r\necho \u201cConnection failed: \u201d . $e->getMessage();\r\n}\r\n?><\/pre>\n
