Saving imagecreate() image in a BLOB

[Anon]

I have managed to save the bindata from a jpeg file into a blob in mysql, however saving the bindata from an imagecreate() call into a blob has totally stumped me!

I've tried this:

ob_start();
imagejpeg($image_thumb);
$image_thumb_string = ob_get_contents();
ob_end_flush();

but when I retreive the picture from the blob is just outputs weird characters.

I know I have the content-type header right and pulling out a blob created from an actual file works fine.

All I need is to know how to get the bindata from a resource indetifer that is returned from imagecreate() and I'll be set!

Thanks

Hey there,

I've found a semi-acceptable solution that uses temporary files, here's a snipet:

// Save the thumbnail to a temporary file
$tmp_filename = "/some/tmp/dir/tmp.jpg";
imagejpeg($image_thumb,$tmp_filename);

// Try to open the file
$fp = @fopen($tmp_filename, "r");
if (!$fp) {
unlink($tmp_filename);
return FALSE;
}

// Extract the picture data
$bin_data = addslashes(fread($fp, filesize($tmp_filename)));

I would still like to do the job without using tmporary files, but this will do for now.
