How to check PHP version?
The URL given is one that works with the script they provide or expect you to write. There's no built-in "magic URL" to show that information with PHP. A HTML page of configuration information can be generated in PHP code using phpinfo() You may also want to pay attention to the top section of phpinfo() output that lists the ini files read, to make sure you're editing the right files. This same information is available on the command line through the following commands: php -i (full information similar to phpinfo()) php -m (enabled modules / extensions) php -v (version) php --ini (ini files read) See also php --help for more command-line options. Note that you can also set most ini settings at runtime in a script using ini_set() . In this specific case see also the error_reporting() function. More on reddit.com

5.6 Zero tests ~14 year old codebase in some parts, most of it is rawdog php and includes. No class structure beyond what we've added for new features. Client actively beligerant at this point to our original agreed goal of them getting 7.x running alongside it on their hardware, and moving portions of the app over as they are worked on, so there's no feature freeze for 12-18 months as it's migrated. They've brought in a second outsourced team as we "aren't moving fast enough" / actually giving a damn to fix security flaws when we find them. This outsourced team is going as well as you'd expect from hearing the term "outsourced team"... Hoping they either get their head out of their ass, or we can cut them off as a client at somepoint. It's just not worth it. More on reddit.com

November 4, 2023 -
hi, I'm new to PHP.
I want to change display_errors to On for debugging, but see many PHP versions installed.
I thought going to http://localhost/first/index.php?language=English&page=phpinfo would give me the version , but it just renders the regular index page.
Ty.

It should be noted that PHP on the command line does not have to be the same version as the one called by the web server. It's also possible for the server to be calling different versions for different sites. If you've many versions installed, it's more likely to be the case. If you can't figure it out from, or don't have access to, the server config, you can check by calling phpversion() within each site. https://www.php.net/manual/en/function.phpversion.php Also, if your server isn't configured not to (ideally it should be, if public), every page will be served with the X-Powered-By header starting which version of PHP is being used.

There isn't (and shouldn't) be an answer with any specific version for this. New versions come out, old versions get discontinued.
At the minimum you should use supported version of PHP. This ensures it still receives bug fixes and (or for less recent version) security updates.
Preferably you should be use the latest stable version of PHP. This ensures you get best possible performance.
PHP site has handy Supported Versions page, which clearly covers currently relevant versions and roadmap for their support.

IMPORTANT EDIT
This has unknowingly came to my attention as it slipped my mind, PHP 5.4 have already reach EOL and the last security support was stopped on the 14th of September 2015.
According to official documentation, PHP 5.5 will finally reach its EOL on the 10 of July 2016 (Active support has already been stopped but this version will still get security updates until its final EOl date of 10 of July 2016).
So to come back to the original question, you should be running on minimum at least PHP 5.5 now, but be sure to get ready to switch to PHP 5.6 within the next 8 months as from date of this answer
ORIGINAL ANSWER
Wordpress are still stuck on the dinosaur PHP versions, so any PHP version newer or equal to 5.3 should do.
It is however very very important to note that all PHP versions prior to version 5.4 have been EOL'ed, the last version being 5.3 a year ago. In short, this means than any PHP version older than 5.4 are no longer supported or updated, which will cause huge security issues if you are still using it.
So, for safety, the bare minimum you should be running safely is PHP 5.4.x, where x should be the latest security release.
In short, to be rather safe than sorry, just like Wordpress, it is always always the best to have the latest available stable release installed.
