Just playing around finding the nicest ways to trap errors in PHP

ErrorStudy.php

<?php
    header("Content-Type: text/plain");

    function my_error_handler($num, $err, $file, $line) {
        echo "Error Occurred: $err\n";
    }

    set_error_handler('my_error_handler', E_ALL);

    try {
        echo "Hello World\n";
        echo $test; // undeclared variable
        $foo = array(); // this is ok
        echo $foo['bar']; // no such index "bar"
        throw new RuntimeException("This is an exception\n");
    } catch(Exception $e) {
        echo "Exception Occurred: " . $e->getMessage();
        exit();
    }
