pthreads在CLI中工作，但在apache服务器中不工作

Question

pthreads recognised in CLI on Ubuntu server but doesn't work in apache2

I've installed pthreads on my Ubuntu 18.04 server using the following tutorial:

https://blog.programster.org/ubuntu16-04-compile-php-7-2-with-pthreads

When I print these lines they both return "1":

php -r "echo PHP_ZTS;"
php -r "print_r(class_exists('Thread'));"

However, when I try to use the Threaded class in php I get fatal error class not found. The php ini file states that Thread Safety is disabled.

Please someone advise me. I've been trying to fix this for hours.

Thanks
