Retrieve extension version in php

Question

Is it possible to get extension version in php?

get_loaded_extensions returns only loaded extentions names, but not versions :(

Only if an extension provides a way of querying its version. — Jon, Jan 31 '13 at 12:53
@Jon All extensions provide a way of their version being queried: `$version = phpversion("extensionName");`. — EM-Creations, Jan 31 '13 at 13:06
What is meant by extension? Extension to Apache, PHP, or browser? — David Spector, Dec 26 '18 at 16:49

I believe this is what you're looking for:

$version = phpversion("extensionName");

note that this does not work with `curl` & `mcrypt`(both return `false`), seems to have been there for a long time: https://bugs.php.net/bug.php?id=40582, no answer found. – samluthebrave May 11 '15 at 09:11
also doesn't work for PCRE (see link in comment above), but you can check the constant `PCRE_VERSION` for version info – webaware Jun 07 '16 at 23:04
OpenSSL is an interesting case, Neither this method nor the Reflection method below return any version information. But OpenSSL instantiates the constants OPENSSL_VERSION_TEXT and OPENSSL_VERSION_NUMBER. Clearly there is no standardized way of getting versions from extensions. – Will Fastie Jan 31 '17 at 14:27

At the command line, where extension is the extension name.

php --re extension | head -1

If unsure of the extension name, list extensions with php -m.

This is not working if you try to detect the version of an extension.dll what is not compatible with your php version – Radon8472 Aug 07 '18 at 20:03

<?php
    $ext = new ReflectionExtension('mysqli');
    var_dump($ext->getVersion());
?>

This returns the same version information as phpversion($extension). I checked 58 extensions, of which 30 returned version information. – Will Fastie Jan 31 '17 at 14:22

Under PHP 7.1-7.3 (more?), both phpversion("extension name") and ReflectionExtension return the PHP version (not the extension version). I guess this is something like the wrapper version, which gets automatically bumped up during release. Not that useful. It does check whether the extension exists (if it doesn't exist it returns null) – Henk Poley Jul 07 '21 at 13:08
Correction, it returns false. – Henk Poley Jul 07 '21 at 13:15
