You can view your PHP settings using a phpinfo page. A phpinfo page is simply a php page with the following code:
<?php
phpinfo();
?>
To view your PHP settings, please take the following steps:
Step 1:
You can access phpinfo page from your browser. If you created the file in your public_html folder, then you would visit http://example.com/phpinfo.php. The results should look similar to the below screenshot:

Step 2:
Search for the line “Thread Safety”. It should give you something like this:
Thread Safety => enabled // Using thread safe PHP
Or,
Thread Safety => disabled // Using non thread safe PHP
