Find if the installed PHP is threadsafe or nonthreadsafe?

How do I find out whether the inst开发者_高级运维alled version of PHP is threadsafe or not thread safe?

Please note that I'm not asking the difference between a threadsafe/non thread safe installation. I would like to find out what is installed currently.

Open a phpinfo() and search for the line Thread safety. For a thread-safe build you should find enable.

As specified in the comments by Muhammad Gelbana you can also use:

• On Windows : php -i|findstr "Thread"
• On *nix: php -i|grep Thread

If you prefer to use the command line:

• *nix:

  php -i | grep -i "Thread"
  

• Windows:

  php -i | findstr -i "thread"
  

This should give you something like this:

Thread Safety => enabled

or

Thread Safety => disabled

I just find it easier to look at the file named php[version].dll in the root folder of php. Its either php[version].dll or php[version]ts.dll (ts standing for Thread Safe). So, if you have php7.0.10 installed, go to the directory that has this name and you'll find a file named php7ts.dll. This is a very sad way of finding out, but it works!

Then there's the undocumented ZEND_THREAD_SAFE constant, which seems to exist since PHP 4.3.

<?php

if (ZEND_THREAD_SAFE) {
    echo 'Thread safe';
} else {
    echo 'Not thread safe';
}

Create a new PHP file and insert this code in it:

<?php
phpinfo(); ?>

Then run this page and you will find all of the PHP information. Search for the term that you want, and it will show you it's enabled.

Check if your install is Apache Module or CGI Binary. See Stack Overflow question What is thread safe or non-thread safe in PHP?.

Another way to check it is using php -v or php --version. Example bellow from mine (NTS):

    $ php --version
