@ Travis: If you use the first approach (the popen() function), you could modify the script to return the file pointer that it creates instead of closing it immediately, and then check its status by calling feof() on the pointer. Something like this: [sourcecode lang="php"] $fp = launchBackgroundProcess($command); //...other code... if (feof($fp)) { //The process has completed. } [/sourcecode] Note: One of the user comments on the popen() page claims that feof() will only ever return TRUE if you try to read from the file pointer at least once. I don't know if this is true, but it's something to keep in mind as a possible source of bugs.

I have been searching for weeks for a solution like this and am so grateful for your work!

Hi Janis,
is there a way to add a callback function/to be notified when the background process is completed? Thanks!

As far as I know, there’s no easy way to do HTTPS with plain sockets (fsockopen). You’ll probably want to change the script to use cURL instead. With an appropriately low connection timeout, cURL should close the connection right away – just like the script above does.

Hi there…this is great! what edits would I need to make if I wanted to do this on an HTTPS request? On cURL I used to do SSL_VERFY_PEER set to false..anything I can do here?

Those are the output parameters for the error number and error message. See the fsockopen documentation for (slightly) more details.

Thank you for this information. Very useful! Question: for the following code, who is $errno and $errstr? $fp = fsockopen($parts['host'], isset($parts['port'])?$parts['port']:80, $errno, $errstr, 30);
