Apache start cannot run pthreads extension

Question

I tried to include pthreads in php.ini as follows:

  extension=ext/php_pthreads.dll

However, it prompts the message when I start apache, I checked the PHP config, it is 5.5.10 and thread safety is enabled. Seems the PHP is alreadt Thread Safe. Do I need to recompile the PHP with --enable-zts config?

The error message is:

PHP Startup: 
pthreads: Unable to initialize module. 
Module compiled with module API=20131226 . 
PHP compiled with module API=20121212. 
These options need to match.

You probably need to downgrade php_pthreads.dll to match the version of the php module you are using, The DLL's signature points to being version 5.6, where as php's signature seems to be 5.5. You might like to check this answer (stackoverflow.com/a/22139183/694576) for a quiet detailed mapping of signatures to versions. — alk

please check that php_pthreads.dll exists in you xampp extension directory.

if it's not exists download and paste it there and then restart xampp.

your problem must be fixed.
