Error Handling In PHP (part 2) - Back To Class (
Page 7 of 8 )
If you're not a big fan of rolling your own code, you might find it
instructive and useful to download the free, open-source ErrorHandler class from
http://www.phpclasses.org/browse.html/package/345.
Created by Gyozo Papp, this PHP class is a robust, full-featured error handler
that can easily be integrated into your application code.
The
ErrorHandler class comes with some very interesting features: the ability to
dump errors to a separate console window so that your primary interface is not
disrupted, to include in that error report the source code which caused the
error, and to append customized error messages or variable context to the error
report. Obviously, it also supports error logging (to a file, an email message,
the system logger, or all three) and can catch and replace PHP's error messages
with a user-defined error template.
Here's a small example of how it
works - take a look at the manual included with the class for more examples and
information.
report_layout('LOGGING', FILE_LOG, 'error.log');
// don't display symbol table
$error->report_layout('CONTEXT', FALSE);
// uncomment this to hide errors and display a customized error template
// $error->set_silent(TRUE);
// $error->set_silent("error.html");
// generate some errors
include('non.existent.file');
mysql_connect("localhost", "baduser", "badpassword");
?>
And here's what it looks like:
