This is the second half of the prior post - how to find out what version of PHP are running on your server. Use curl with the -I (uppercase i) option, followed by the domain name to get the HTTP headers. There are many options you can use with curl, and the server can be configured to suppress some of this information for improved security - so if you don’t get the results you need, refer to the man pages and try again.

HTTP/1.1 200 OK

Another approach is to create one file, ver.php, and link to it called ver.php5. It should contain the following:

echo phpversion();

Request both URLs through a browser to see what version is used to deliver them.
