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.
