In other words, your code would look something like this:
$charturl = "http://chart.apis.google.com/chart?cht=lc&chco=" . implode(',', $colors) . "&chs=930x310&chd=t:" . implode('|', $graphdata) . "&chxt=x,y&chxl=0:|" . implode('|', $monthsheading) . "|1:|10|20|30|40|50|60|70|80|90|100"; $pdf->Image($charturl, null, null, 180, 60, 'PNG');
99% of the time though, my PDF fails, gives me an error about not being able to load the image and leaves me in tears.
Because each and every time, I can without fail go look at the PHP error log and will be greeted with this:
failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request
And then I remember: URLENCODE the damn graph string before feeding it into the Image function!
One day I’ll remember to do this from the get go, promise! :)
