Solution to Trying to clone an uncloneable object of class Imagic_PHP Tutorial

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, changing it to Off will solve the problem.

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.

Attached is the program code snippet for converting pdf to png:

Copy the code The code is as follows:

function pdf2png($pdf, $filename, $page=0) {                                                                             
                                                                           file_exists($pdf)) {
                                                                                                                                                                                     🎜> $im-> ;setCompressionQuality(100);
            $im->readImage($pdf . "[" . $page . "]");                             im->writeImage($filename);
   $ im->writeImage($filename);
