I am trying to enable Thread with PHP script. I have followed the following steps for enabling PHP thread.

Step 1:- Download and unzip pthread lib from here

Step 2:- Copy php_pthreads.dll and paste into the php\php7.2.14\ext and php\php7.2.14\ folder.

Step 3:- and pthreadVC2.dll and paste into the apache\apache2.4.37\bin

Step 4:- Enable thread in php.ini which is located in apache\apache2.4.37\bin and after updating its look like something below.

; Whether or not to enable the dl() function.  The dl() function does NOT work
; properly in multithreaded servers, such as IIS or Zeus, and is automatically
; disabled on them.
; http://php.net/enable-dl
enable_extension=On
extension=php_pthreads.dll

Step 5:- Enable thread in php.ini in which located at \php\php7.2.14

; Whether or not to enable the dl() function.  The dl() function does NOT work
; properly in multithreaded servers, such as IIS or Zeus, and is automatically
; disabled on them.
; http://php.net/enable-dl
enable_dl = On
extension=php_pthreads.dll

Step 6:- I have restarted wampp server with all services.

Still, I am getting the error as 

 Fatal error: Class 'Thread' not found in {PHP file with location with line number}.

Update

I have changed DLL files and restarted a server as we discussed and redirect to a new error as below. 

[24-Jan-2019 10:29:20 UTC] PHP Fatal error:  The apache2handler SAPI is not supported by pthreads in Unknown on line 0
[24-Jan-2019 10:29:20 UTC] PHP Fatal error:  Unable to start pthreads module in Unknown on line 0

  • It seems like you're using the extension for 7.0 and not 7.2. Check this issue on their Github for a link to a version that should work for 7.2 (it's still set as version 3.1.6, but has -7.2 instead of -7.0). Commented Jan 24, 2019 at 10:13

    If you are using WAMPServer as you say, then #!/usr/bin/php will not be understood by Windows! Commented Jan 24, 2019 at 10:33

    Please read the comments properly again. As stated, you were using the wrong version of the dll (and the github issue linked to a working one for PHP 7.2). Then it also states that it does not work on web servers, which includes Apache (which is a web server). So, even after upgrading the dll to the correct version, you still can't use it with Apache (or any other web server). It only works on PHP-scripts that are executed through the command line (like cmd etc). Commented Jan 24, 2019 at 10:53
