Force File for Download using Php | Download File on Click URL

1.       Upload the file you want to make available for download to your hosting Web server.

For example,

myhtml.html

2.       Create one another a new PHP file - I recommend naming it the same name as your downloaded file, only with the extension .php. For example:

myhtml.php

3.       Open the PHP block:

<?php

//  set the HTTP header:

header('Content-disposition: attachment; filename= myhtml.html');

// Then set the MIME-type of the file:

header('Content-type: application/html');

// Point to the file you want to download:

readfile('myhtml.html');

?>

4.       Link to your PHP file as a download link. For example:

<a href="myhtml.php">Download my html document </a>
