How Can I Efficiently Load .SQL Files into a Database Using PHP?

PHP's Approach to Loading .SQL Files

One of the crucial tasks in software development involves managing databases. PHP, a widely adopted programming language, offers robust capabilities for database manipulation. One such task is loading .sql files into a database, which can pose challenges due to the complexity of SQL schema files.

To successfully perform this operation, the recommended approach is to utilize PHP's excellent PDO (PHP Data Objects) extension. With PDO, you can instantiate a database connection, read the contents of your SQL file, and execute it in the database. Here's how you can put it into practice:

$db = new PDO($dsn, $user, $password);

$sql = file_get_contents('file.sql');

$qr = $db->exec($sql);

Using file_get_contents(), you retrieve the entire contents of the .sql file into the $sql variable. Then, using exec(), you execute this data directly against your database connection, successfully loading the SQL file.

The key advantage of this approach is that it handles complex SQL files efficiently, even those containing multiple queries in a single line. So, next time you need to dynamically create databases and populate them with .sql files in PHP, remember this simple technique to streamline your workflow.
