What are the potential implications of using different storage engines like MyISAM and InnoDB in PHP applications?

Using different storage engines like MyISAM and InnoDB in PHP applications can have implications on performance, data integrity, and features available. MyISAM is faster for read-heavy operations but lacks support for transactions and foreign keys, while InnoDB is better suited for write-heavy operations and supports transactions and foreign keys. To ensure compatibility and optimize performance, it's important to choose the appropriate storage engine based on the specific requirements of the application. 

// Specify the storage engine when creating a table in MySQL
$sql = "CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL
) ENGINE=InnoDB;";
$result = mysqli_query($conn, $sql);
if (!$result) {
    echo "Error creating table: " . mysqli_error($conn);
}
