PHP Fatal error Uncaught exception Exception

Question

I m playing around with exceptions in PHP  For example  I have a script that reads a   GET request and loads a file  If the file doesn t exists  an new exception should be thrown   if   file exists    SERVER  DOCUMENT ROOT          GET  image                Something real amazing happens here    else       throw new Exception  The requested file does not exists         The problem is that  when I try to supply an non existent file for the test  I got a 500 error instead of the exception message  The server log is the following    09-Jul-2013 18 26 16 UTC  PHP Fatal error   Uncaught exception  Exception  with message  The requested file does not exists   in C  sites wonderfulproject script php 40 Stack trace   0  main    thrown in C  sites wonderfulproject script php on line 40   I wonder if I m missing something real obvious here   I ve checked this question PHP fatal error  Uncaught exception   39 Exception  39  with message but it s not quite like my issue  and have no concise answer   Help  please     EDIT    It seems this is something related to the throw keyword  If I use echo for example  I got the message printed on the screen  like this   exception  Exception  with message  The file does not exists   in C  sites wonderfulproject script php 183 Stack trace   0  main   Why is that      EDIT 2     Thanks to  Orangepill  I got a better understanding about how to handle exceptions  And I found a superb tut from nettuts that helped a lot  The link   http   net tutsplus com tutorials php the-ins-and-outs-of-php-exceptions

This is expected behavior for an uncaught exception with display_errors off.

Your options here are to turn on display_errors via php or in the ini file or catch and output the exception.

 ini_set("display_errors", 1);

or

 try{
     // code that may throw an exception
 } catch(Exception $e){
     echo $e->getMessage();
 }

If you are throwing exceptions, the intention is that somewhere further down the line something will catch and deal with it. If not it is a server error (500).

Another option for you would be to use set_exception_handler to set a default error handler for your script.

 function default_exception_handler(Exception $e){
          // show something to the user letting them know we fell down
          echo "<h2>Something Bad Happened</h2>";
          echo "<p>We fill find the person responsible and have them shot</p>";
          // do some logging for the exception and call the kill_programmer function.
 }
 set_exception_handler("default_exception_handler");

Just adding a bit of extra information here in case someone has the same issue as me   I use namespaces in my code and I had a class with a function that throws an Exception   However my try catch code in another class file was completely ignored and the normal PHP error for an uncatched exception was thrown   Turned out I forgot to add  use  Exception   at the top  adding that solved the error
