PHP imagecreatefromstring(): gd-jpeg, libjpeg: recoverable error

Question

I'm trying to load an image from an external site over which I have no control.

Most of the time it works fine (hundreds of images tested so far).

It's now giving me this error for one particular image:

imagecreatefromstring(): gd-jpeg, libjpeg: recoverable error: Corrupt JPEG data: premature end of data segment

from this line:

$im = @imagecreatefromstring( $imageString );

The advice I'd read so far suggests adding:

ini_set("gd.jpeg_ignore_warning", true);

but that's had no effect and I'm still getting the error. I'm doing the ini_set just before the call. Is that relevant?

I'm really stuck on how to ignore this error and carry on.

Answer 1

The problem was due to my error handling. I'd set up an error handler so my call to

$im = @imagecreatefromstring( $imageString );

wasn't suppressing errors.

By modifying my error handler with:

   if (error_reporting() === 0)
   {
        // This copes with @ being used to suppress errors
        // continue script execution, skipping standard PHP error handler
        return false;
   }

I can now correctly suppress selected errors.

Answer 2

this can be solve with:

ini_set ('gd.jpeg_ignore_warning', 1);
