Help with purge from PHP

  • I wrote the following PHP script code to purge the entire varnish cache on our site:

    // Construct Varnish Cache purge URL
$scheme = parse_url( $_SERVER[HTTP_REFERER], PHP_URL_SCHEME );
$host = parse_url( $_SERVER[HTTP_REFERER], PHP_URL_HOST );
$tmpURL = $scheme . "://" . $host . "/?vhp_flush_all=1" ;
$purgeURL = wp_nonce_url( $tmpURL, 'vhp-flush-all') ;

// Do the purge
file_get_contents( $purgeURL );

    This code was working fine but recently I am getting the following error when it executes –
    Warning: file_get_contents(https://www.n1fd.org/?vhp_flush_all=1&_wpnonce=a44652dfad): failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in …

    If I execute the same URL from by browser, the purge works fine. I am obviously doing something wrong here – can you help me to understand how to correctly purge the varnish cache from PHP?

    P.S. This code is only run by users with admin permissions.

    I wrote the following PHP script code to purge the entire varnish cache on our site:

    Why? If, as you say, it’s only run by admins, then they can just press the purge button in the toolbar, which does the same thing.

    Thank you for getting back to me Mika. I have a script which handles several levels of purging depending upon what I am doing. Steps include varnish purge, a css and java compression cache, and an external CDN. It’s useful for our admins to be able to just click a link based upon what they need and the php script handles all of the steps in the correct order.

    I hate to phrase it this way, but you don’t NEED this plugin then ??

    If you’re writing a script that does all that, just put the actual curl -X PURGE https://yourdomain.com/.* command right in the script? Wouldn’t that be faster?
