Remove query string from stylesheet path

[swissspidy]

In my simple PHP file I reference my stylesheet as follows:

<link rel="stylesheet" href="css/style.css?v=<?php echo filemtime( 'css/style.css' ); ?>"

When using the CLI, I get the following error:

Error: File not found: css/style.css?v=<?php echo filemtime( 'css/style.css' ); ?>

This could be addressed by automatically removing query strings like ?v before trying to access the file. After that it works as expected.
