What are the advantages and disadvantages of using a Blob data type to store PDF files in a MySQL database in PHP?

Storing PDF files as Blobs in a MySQL database can simplify data management by keeping all data in one place. However, this approach can lead to performance issues as Blobs can be large and impact database performance. Additionally, it may be more difficult to retrieve and manipulate the files compared to storing them in a file system. 

// Example of storing a PDF file as a Blob in a MySQL database
$pdo = new PDO('mysql:host=localhost;dbname=test', 'username', 'password');

$pdfContent = file_get_contents('example.pdf');
$stmt = $pdo->prepare('INSERT INTO pdf_files (file_data) VALUES (?)');
$stmt->bindParam(1, $pdfContent, PDO::PARAM_LOB);
$stmt->execute();
