PHP7 compatible?

For further detail, this is what the PHP7 Compatibility Checker is reporting:

wp-content/plugins/dynamic-to-top/inc/cssmin-v3.0.1.php
--------------------------------------------------------------------------------------------------------------------------
FOUND 2 ERRORS AFFECTING 2 LINES

@webtaurus, did you upgrade your site since you posted here? Any results to report running this plugin version 4.6.1 on PHP7?

I get the same error reported using siteground’s php7 compatibility checker with wordpress 4.7.3 installed.

Yep, came to report the exact same 2 errors before attempting to upgrade to PHP7.

The problem are at file wp-content/plugins/dynamic-to-top/inc/cssmin-v3.0.1.php. It’s because clone is a keyword, not a function, therefore:

clone( $date ) ?
clone $date ??

It’s easy solve this error.

In line 3346 you must change:
$source[] = clone($tokens[$iii]);
by:
$source[] = clone $tokens[$iii];

In line 3353 you must change:
$t[] = clone($token);
by:
$t[] = clone $token;

Let’s hope the author solves this problem soon.
