How can PHP developers optimize the storage and retrieval of large video files in their applications?

To optimize the storage and retrieval of large video files in PHP applications, developers can utilize cloud storage services like Amazon S3 or Google Cloud Storage. By storing the videos on these services, developers can offload the storage burden from their servers and leverage the scalability and reliability of these platforms for efficient retrieval.

// Example of storing a video file on Amazon S3 using the AWS SDK for PHP
require 'vendor/autoload.php';

use Aws\S3\S3Client;

// Instantiate an S3 client
$s3 = new S3Client([
    'version' => 'latest',
    'region' => 'us-east-1',
    'credentials' => [
        'key' => 'your_access_key',
        'secret' => 'your_secret_key',
    ]
]);

// Upload a video file to S3
$result = $s3->putObject([
    'Bucket' => 'your_bucket_name',
    'Key' => 'video.mp4',
    'SourceFile' => '/path/to/video.mp4',
]);

echo 'Video uploaded to S3: ' . $result['ObjectURL'];
