//***************************************************************
//** title : Error mailing logging facility
//**
//** file : error.php
//**
//** story : When your site is live you never want people to see
//** php errors no matter what. Sometimes this is possible
//** though because your host might upgrade PHP or MySQL
//** or something else can go bad. The usual advice given
//** is to have error_reporting(0) on the live sites. But
//** then you will never get to know that an error is there.
//**
//** I use a different approach here. I set error reporting
//** to E_ALL (that is report all errors) but I have
//** over-ridden the error handler to construct a nice
//** error report and mail it to me. The application
//** continues, and if the error was not major, the user
//** will never get to notice anything. You on the other
//** side though will know that something has gone wrong
//** and you'll run to fix it.
//**
//** Customize the $to and $from variables, include this
//** file and enjoy.
//**
//** You are going to get something like this:
//**
//** Date : December 3, 2005, 3:55:12 am
//** Server : example.com
//** Error No: 8
//** On file : /home/example/public_html/temp/error.php
//** On line : 35
//** Error : Use of undefined constant bar - assumed 'bar'
//** IP : 87.203.242.37
//** Host : athedsl-12355.otenet.gr
//** Method : GET
//** Vars :
//** name => test
//** age = 55
