converting blob image to file in php

Question

I\'m currently using a simple $_FILES upload script to upload pictures from my iPhone app to server. The image sizes, however, are large and I\'d like to resize them before

Answer 1

The BLOB is the binary image. You can write that image to your filesystem once it's on your server. So if your image is in the variable $my_blob, you would do something like

file_put_contents('/path/to/new/file_name', $my_blob);

and there you go.

You might want to save the file to a tmp location first, then do some checks on it before you move it to a final location (with PHPs rename() function).

Btw: why not just save the BLOB to DB? That is a legitimate way of handling files these days, that's what the BLOB MySQL data type is for after all.

Answer 2

Try just writing it to a file with an image/[fill-in-the-blank] mimetype. Or maybe imagecreatefromstring will work. (NOT sure about any of these)

Or you can find another way to resize the images.
