Imagick::destroy() has been deprecated in favor of Imagick::clear().

Destroy and clear methods seem to do exactly the same thing

@see http://svn.php.net/viewvc/pecl/imagick/trunk/imagick_class.c?view=markup (l.3066 & l.3087)



The code is duplicated, they do the same thing a bit differently.

One might be suprised that there seems to be no difference between:



<?php

$imagick = new Imagick();

$imagick->clear();

$imagick->readImage('myfile.jpg');

?>



and



<?php

$imagick = new Imagick();

$imagick->destroy();

$imagick->readImage('myfile.jpg');

?>



Both functions reset all options and clear all used resources so you might want to use either one of them.
