Thanks in advance. EDIT: I don't know what PHP_open_image_file does, but sometimes I get errors like below, and I need to get the product identifier that is causing php error handling the error. Fatal error: PDFlib error [1016] PDF_open_image_file: Couldn't open JPEG file 'picture/b01_le1x.jpg' for reading (file not found) in /var/www/html/catalogue/pdf_make.php on line 618 php error-handling php4 share|improve this question edited Nov 16 '10 at 23:51 asked Nov 16 '10 at 23:27 Aximili 10.7k37108146 4 Why are you still using PHP4? –drudge Nov 16 '10 at 23:28 +1 The server for this thing is still using PHP4 =.=" –Aximili Nov 16 '10 at 23:36 2 My condolences. If PDF_open_image_file throws an exception, will it even run as-is in PHP4? Seems like you'd have to rearchitect the whole thing. –deceze Nov 16 '10 at 23:43 lol thanks! I have updated the question –Aximili Nov 16 '10 at 23:55 2 Tell your host to not suck and update to PHP5 –ThiefMaster♦ Nov 16 '10 at 23:59 | show 1 more comment 2 Answers 2 active oldest votes up vote 4 down vote accepted Am I correct in assuming you are using PDF_open_image_file() from the pdflib PECL extension? If so, then it will never throw an exception on PHP 4. I would assume error states are reported through the result, which is an int and thus probably < 1 in case of errors. //try if (file_exists($imgFile)) { $picture = PDF_open_image_file($PDF, "jpeg", $imgFile, "", 0); } //catch if (!$picture) { $msg = "Error opening $imgFile for Product $row['Identifier']"; prin
