How to write a code for video streaming in php

 Here's a simple example of how to stream a video file in PHP:

php
<?php
// Specify the video file path 
$file = 'path/to/video.mp4'; 
// Check if the file exists 
if (file_exists($file)) { 
// Set the appropriate headers for video streaming 
header('Content-Type: video/mp4'); 
header('Content-Length: ' . filesize($file)); 
// Stream the video content 
readfile($file);
  exit;
} else { 
// Handle the case if the file does not exist 
header("HTTP/1.0 404 Not Found"); 
echo 'File not found';
  exit; 
}
?>

This code will read the specified video file and send its contents to the client using the appropriate Content-Type and Content-Length headers. The video content is streamed using the readfile function. If the file does not exist, it will return a 404 Not Found error.
