[Resolved] fsockopen & "silent execution" question

tomfra

I am using this code to execute one command:

    $fp = fsockopen($domain, 80, $errno, $errstr);

if (!$fp) { echo "$errstr ($errno)<br>\n"; } else {

$out = "GET ".$_SERVER['PHP_SELF']."?com=cache&pass=$password HTTP/1.1\r\n";
$out .= "Host: $domain\r\n";
$out .= "Connection: Close\r\n\r\n";

fwrite($fp, $out);

while (!feof($fp)){
  echo fgets($fp,32000); 
}

This code works, it does indeed sends the GET request properly. But when I execute this code directly from the web browser, the "com=cache" command is beign processed in the real time just like if I executed it directly and not through fsockopen.

What I'd like to do is to 'force' the server to send the GET request, finish the job on the server and then notify me via email (for example) when the job is done. The reason for this is that the "cache" command can take several hours to finish.

I hope I explained it good enough... The point is, the work should be done "silently" on the server just like if the code was executed through Cron job.

Thanks!

Hi,

do you have a Unix/Linux server or a Windows server ?

This script should run on Linux / Unix servers only.

Ok,

if wget or the CLI version of PHP is installed on that server(s) then try something like

system("/path/to/nohup /path/to/php/executable -q /path/to/php/script.php &");

or if wget is installed and you want to call the script through the web server:

system("/path/to/nohup /path/to/wget -q http://thehost/path/to/php/script.php &");

using "nohup ... &" the programs should go to background.

without nohup just using the & at the end of the line the process will be killed if the web server gets restarted/stopped.

That might not work if any safe_mode restrictions are active.

Alternatively, you can use lynx if available.

The wget way seems to do the job correctly except that it's not being done in the background. A major problem for me...

I got it! Adding ">/dev/null &" instead of just "&" did the trick.

Thanks a lot!
