Errors and Logging sample source codes – PHP Scripts

Building a basic error handler with custom error types

’.$error_message,’ (An error type ‘,$error_type,’ occurred). The administrator has been notified. This page might not function correctly.
’;   
    break; 
      
      
    case E_WARNING: 
    case E_USER_WARNING: 
    // Add your own code here! 
    echo ‘
’.$error_message,’ (An error type ‘,$error_type,’ occurred). The administrator has been notified. This page might not function correctly.
’; 
    break; 
 
    case E_NOTICE: 
    case E_USER_NOTICE: 
    // Add your own code here! 
    echo ‘
’.$error_message,’ (An error type ‘,$error_type,’ occurred). The administrator has been notified. This page might not function correctly.
’; 
    break; 
     
    case BIG_SCARY_ERROR: 
    echo ‘A *huge* scary error has been seen skulking around on line ‘.$error_line.’ of ‘.$error_file.’! It\’s shouting « ‘.$error_message.' »‘; 
    break; 
    } 
return true; 
  } 
 
} 
 
?> 
 
To use this error handler, put in in a file, and include it into your script. Then, instantiate it (eg $error_handler = new error_handler() ). The whenever an error occurs, the class will catch it. To trigger your own errors do: 
 
trigger_error(‘error message typed here’, E_USER_ERROR); 
(where the bit in capitals is the type you want to trigger). 
So you can do this to trigger a custom error type: 
 
trigger_error(‘I’m going to eat your PHP code!!! Bwahahahahaaa’, BIG_SCARY_ERROR);
