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. Answer from allen_jb on reddit.com

r/PHPhelp on Reddit: How to check PHP version?
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.

$version = phpversion();
print $version;

However, for best practice, I would use the constant PHP_VERSION. No function overhead, and cleaner IMO.
Also, be sure to use version_compare() if you are comparing PHP versions for compatibility.

Technically the best way to do it is with the constant PHP_VERSION as it requires no function call and the overhead that comes with it.
php 5
echo $PHP_VERSION;
That does not work in 7+ however, you can use:
php7.x
echo PHP_VERSION;
Not sure about php8.x though. constants are always faster then function calls.
