PHP - How to write image resource to file

问题

I used function imagecopyresampled to cropping image.

I tried use file_put_contents and fwrite to write the resized_image to file on hard disk but all attempts were failed.

Can I write the resized image to disk instead of using imagejpg to print it out to browser?

回答1:

Here's the function signature for imagejpeg():

bool imagejpeg ( resource $image [, string $filename [, int $quality ]] )

So, provide your destination filename as the second argument. (Standard filesystem permission warnings apply, make sure the process has write access to that directory.)
