Using JS to cut the picture after the return of the Dataurl, how can be saved as a picture file?

In fact, there is no need toDataURL , you can toBlob upload directly, you can also save a bit of traffic. Chrome isn't natively supported yet toBlob , but it's easy to find Polyfill. Firefox is already natively supported toBlob .

Of course, if and the data URL is uploaded to the server, take the content after the comma base64_decode is enough.

The general transmission is Base64, after the PHP, as the upstairs said, Base64 decode a bit.
Then simply and rudely said, file_put_contents a bit on the OK.
