php上传图片，重命名，缩略图，并保存两者

Question

Ive been looking at the move_upload_files function, but i dont think thats what i need.

I need to upload a picture (max size 2mb png, jpg, gif only) then rename it, then create a thumbnail of it, and save both to the same directory. I figure ill upload/rename the main file first, then take that and create the thumbnail. But what functions should i be looking at to do this?

Answer 1

You will at least need to look at PHP's GD functions, or better yet Imagick for creating thumbs.

There are zillions of tutorials on this, here are a couple:

• http://www.webcheatsheet.com/php/create_thumbnail_images.php
• http://icant.co.uk/articles/phpthumbnails/
• http://php.about.com/od/advancedphp/ss/php_thumbnail.htm

Or you could just use a ready-made solution, e.g.:

• http://phpthumb.sourceforge.net/
