Php session_start general error handling

Question

I'm looking for a general way to handle session_start errors, not a way to deal with one specific error. There are many errors that can occur, such as a full session directory, that cause a fatal error. I want to catch these errors and handle them cleanly, without having to write custom handlers for every opportunity.

Something like this (but not this, as it does not work):

 try{ session_start(); }catch(Exception $e){ echo $e->getMessage(); } 

All help is appreciated, thanks in advance.

Regular PHP session functions do not throw exceptions, but throw errors. Try writing an error handler function and installing an error handler before calling session_start .

 function session_error_handling_function($code, $msg, $file, $line) { // your handling code here } set_error_handler('session_error_handling_function'); session_start(); restore_error_handler(); 

However, this is just for capturing session errors. The best way would be to create a common error handler that throws exceptions from errors and parts of the spatial code that can cause errors using try ... catch blocks.
