How can PHP developers optimize the process of storing files in a database while maintaining performance?

To optimize the process of storing files in a database while maintaining performance, PHP developers can use a combination of techniques such as storing file metadata in the database and storing the actual file in a file storage service like Amazon S3. This way, the database is not burdened with large file storage, and retrieval can be faster as well. 

// Store file metadata in the database
$filename = 'example.txt';
$fileSize = filesize($filename);
$fileType = mime_content_type($filename);

// Insert metadata into the database
$query = "INSERT INTO files (filename, size, type) VALUES ('$filename', $fileSize, '$fileType')";
$result = mysqli_query($connection, $query);

// Store the file in a file storage service like Amazon S3
$s3 = new Aws\S3\S3Client([
    'version' => 'latest',
    'region' => 'us-west-2',
    'credentials' => [
        'key'    => 'your-aws-access-key',
        'secret' => 'your-aws-secret-access-key',
    ],
]);

$result = $s3->putObject([
    'Bucket' => 'your-bucket-name',
    'Key'    => 'example.txt',
    'Body'   => fopen($filename, 'r'),
]);
