Retrieve extension version in php

问题

Is it possible to get extension version in php?

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

回答1:

I believe this is what you're looking for:

$version = phpversion("extensionName");

More information

回答2:

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.

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