Upload script with images with a file size greater than 20 MB.

Hello everyone.

I'm looking for a book in PHP and MySQL, which are examples of an upload script with images with a file size greater than 20 MB. The script must be able to write the image and create thumbnails and put it into another folder. Example: images (large files) and (thumbs small files).
I know the script from your book: Beginning PHP5, Apache and MySQL Web Development, but the script makes mistakes when the file size is too big. (There are not created thumbnails.) Otherwise it works perfectly.
I want to create a picture gallery, where people are able to upload their photos from their digital camera. These files may have a file size greater than 20 MB.
Can anyone help me?

Go through your php.ini, find those settings, and make the changes:

Code:

post_max_size = 30M 
; or some other number that's bigger than 20M
upload_max_filesize = 30M
; or some other number that's bigger than 20M
memory_limit = 128M
; this is the default for me, make sure it's big enough
max_input_time = -1
; -1 is unlimited, or set as needed

At the beginning of your script, add this line:

Code:

set_time_limit(0);

Thanks PeterPeiGuo for your answer, but it's not exactly what I need. I must do and know the code for such a script. I can refer to link: http://phpfileuploader.com/demo/form-simple-upload.php or something else.
Hope I can find help here.

All the best

Jens

What Peter means is that this is the only difference between a standard PHP upload script and one which allows you to upload "mega" files. The PHP code for uploading files of any type and size is identical. The problem with large files is that the server won't allow it. Peter responded with the configuration settings in PHP (and there may be some Apache settings, I don't know) that you need to switch. This is why I hate server administration.

Yuck.

That said, be REALLY sure that you need to upload files of this size. The reason servers don't let you do this normally is that it's a bad idea to give your users this power. If you do, expect high server loads. Depending on your package, your webhost may require that you buy a more expensive package, or they may charge you very high fees for exceeding your bandwidth. At the very least, consider if there are some roles which should have access to mega-uploads and others that should not. That will give you at least a minimal level of control.
