Cannot retrieve the version of an extension

Description

Description

When calling phpversion($extension) or using ReflectionExtension::getVersion() for any PHP extension, the returned value is the current PHP version (8.4.2 in my case) instead of the specific version of the extension.

The only exception observed is the xdebug extension, which correctly returns its version. This issue affects all other extensions tested, including core extensions like tidy, curl, and others.

Steps to Reproduce

1. Use the following code snippet:

   <?php
   echo "PHP Version: " . PHP_VERSION . PHP_EOL;
   
   $extensions = ['mysqli', 'curl', 'xdebug'];
   foreach ($extensions as $ext) {
       echo "phpversion('$ext'): " . phpversion($ext) . PHP_EOL;
   
       $reflection = new \ReflectionExtension($ext);
       echo "ReflectionExtension::getVersion('$ext'): " . $reflection->getVersion() . PHP_EOL;
   }

2. Run the script.

Expected Result

phpversion($extension) and ReflectionExtension::getVersion() should return the version of the specified extension, not the PHP version.

Actual Result

For most extensions, both functions return the PHP version (8.4.2) instead of the extension version. The xdebug extension is the only one that behaves correctly.

PHP Version

8.4.2

Operating System

Tested on Windows 10 throught Wampserver 3.3.7 64 bits.

This is expected, all extensions from PHP don-t have specific version (oci8, zip are exceptions)

Only extension installed manually (from pecl or pie) use their own version

In this case, according to the documentation, phpversion() should returns false and ReflectionExtension::getVersion() should returns null.

Can you quote the documentation parts that you are referring to?

[SigmaFlame]

phpversion

Returns the current PHP version as a string. If a string argument is provided for extension parameter, phpversion() returns the version of that extension, or false if there is no version information associated or the extension isn't enabled.

ReflectionExtension::getVersion

The version of the extension, or null if the extension has no version.

[TimWolla]

The quoted statements say that false or null is returned when no version information is available, but this is not the case. The extensions have a version, it matches the PHP version.
