What are best practices for handling blob data in PHP?

When handling blob data in PHP, it is important to properly handle the data to prevent any security vulnerabilities or data corruption. Best practices include using prepared statements to prevent SQL injection attacks, validating and sanitizing user input before storing it in the database, and using appropriate data types for storing blob data. 

// Example of handling blob data in PHP using prepared statements

// Establish database connection
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare SQL statement with a placeholder for the blob data
$stmt = $pdo->prepare("INSERT INTO mytable (blob_column) VALUES (:blobData)");

// Bind the blob data to the placeholder
$stmt->bindParam(':blobData', $blobData, PDO::PARAM_LOB);

// Read the blob data from a file
$blobData = file_get_contents('path/to/blobfile');

// Execute the statement
$stmt->execute();
