Here i am testing with header functions which will allow me to download a mp4 file from browser.I have a file which is 94 megabyte in size.But when i click the download button i get a file which is only 273 kilobyte long.What might be the reason behind this situation and how i can solve this ?
<?php
if(isset($_POST['mymp4'])){
header('Content-Type: video/mp4');
header('Content-Disposition: attachment; filename="'.$_POST['mymp4'].'"');
}
?>
<html>
<body>
<form action='<?php echo $_SERVER["PHP_SELF"]; ?>' method='POST'>
<input type='hidden' value='Design Patterns for JavaScript Web Apps -- JavaScript Confer.mp4' name='mymp4'>
<input type='submit' value='download mp4' />
</form>
</body>
</html>
Try
header("Content-Type: video/mp4");
header("Content-Length: ".filesize("path/to/mp4"));
readfile("path/to/mp4");
