Solution to cloneable Trying to clone an uncloneable object of class Imagic

After installation under windows, the prompt is:
Fatal error: Trying to clone an uncloneable object of class Imagick in C:wwwhxpdf_to_png.php on line 17

This prompt will appear when using IIS and Apache. After many tests, two solutions were found:

1.php.ini; Enable compatibility mode with Zend Engine 1 (PHP 4.x)
zend.ze1_compatibility_mode = Off

The default is On, after changing it to Off , can be solved.

2. Use imagick::... to call.
That is, $im->setResolution(120, 120); can be rewritten as:
imagick::setResolution(120, 120);

If this kind of error occurs in other extensions, these two methods can generally be used to solve it. .
