What best practices can be followed in PHP to efficiently handle and process large amounts of video files (such as 25 Terabytes) for extracting Exif data?

To efficiently handle and process large amounts of video files for extracting Exif data in PHP, it is recommended to use a combination of batch processing, memory management, and optimized file handling techniques. This includes reading and processing files in chunks, using efficient memory allocation strategies, and utilizing libraries or tools specifically designed for handling large files. 

<?php
// Example code snippet for processing large video files in PHP

// Set memory limit to handle large files
ini_set('memory_limit', '-1');

// Open directory containing video files
$dir = '/path/to/video/files';
$files = scandir($dir);

foreach ($files as $file) {
    // Check if file is a video file
    if (pathinfo($file, PATHINFO_EXTENSION) == 'mp4') {
        // Process video file to extract Exif data
        $exifData = exif_read_data($dir . '/' . $file);
        
        // Save or output extracted Exif data
        var_dump($exifData);
    }
}
?>
