Php Error Types
when there is a fatal error I need to get the $row['Identifier'] so I know what product is causing the error. 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 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 10.8k37108146 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.

This function can be used for defining your own way of handling errors during runtime, for example in applications in which you need to do cleanup of data/files when a critical error happens, or when you need to trigger an error under certain conditions (using trigger_error()).

{$mysqli = @new mysqli('localhost', 'username', 'password', 'db_name');
if ($mysqli->connect_errno)
{
return false;}
