How can PHP developers efficiently manage and store binary values in MySQL databases?

To efficiently manage and store binary values in MySQL databases using PHP, developers can use the BLOB (Binary Large Object) data type in MySQL to store binary data such as images, files, or other binary data. When inserting binary data into the database, developers should use prepared statements to prevent SQL injection attacks and ensure data integrity. Retrieving binary data from the database can be done using PHP's file handling functions to read and display the binary data. 

// Inserting binary data into MySQL database
$binaryData = file_get_contents('image.jpg');
$stmt = $pdo->prepare("INSERT INTO table_name (binary_column) VALUES (:binaryData)");
$stmt->bindParam(':binaryData', $binaryData, PDO::PARAM_LOB);
$stmt->execute();

// Retrieving binary data from MySQL database
$stmt = $pdo->prepare("SELECT binary_column FROM table_name WHERE id = :id");
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();
$row = $stmt->fetch();
$binaryData = $row['binary_column'];

// Displaying binary data
header("Content-Type: image/jpeg");
echo $binaryData;
