PHP: Implemented display of exception message when exception breakpoints are hit

[troizet]

The implementation is made for xdebug since version 3.1.6.
Tested on versions of xdebug: 3.1.6, 3.2.0, 3.3.0.

Code example:

<?php

class MyException extends Exception
{}

function throwException()
{
    throw new MyException("Test exception breakpoint", 42);
}

echo 'Test exception breakpoint';

$foo = $bar['foo'];

try {
    throwException();
} catch (Exception $e) {}

before:

before.mp4

after:

after.mp4

for throw new MyException("Test exception breakpoint") it looks like this:

for throw new MyException("", 42) it looks like this:

for throw new MyException("") and throw new MyException() it looks like this:
