How to avoid 'Cannot redeclare class' error?

Yii 1.1 General Discussion

I use Image extension(http://www.yiiframework.com/extension/image) to resize multiple images from a html form in a loop


		$image = Yii::app()->image->load($ori_dir.$file);

		$image->resize(120,120)->quality(60);

		$image->save($m_dir.$file);

		$image->resize(100,100)->quality(50);

		$image->save($s_dir.$file);

and I encountered:


Fatal error: Cannot redeclare class Image_GD_Driver in PATH_TO\GD.php on line 380

How to deal with this? Thanks.

Solved:change ‘include’ in line 123 in GD.php to ‘include_once’ helps.

Don’t know why the author used include.

include is faster then include_once, the latter will check if file has been included so this checking will cost some time ,but in loop or recursion scenario “include” may bring some trouble as you met :lol:
