PHP: Embed debugging info in output?

Question

Is there an easy way to get PHP to output a stack trace in an HTML comment everwhere it produces output? I am using xdebug, but being able to search through a massive dump would be helpful when I am placing breakpoints in the wrong place.

Hell is other people's code

Answer 1

No direct way exists.

Indirectly, you may include a DIV element in the target page:

<div id="debugInfo">
 ...
</div>

Fill the DIV with the debug info you'd like to know.

Use CSS and JavaScript reduce the size of the DIV to e.g. 20 x 10 px by default.

Using an onmousedown event, maximize the DIV element. On the next onmousedown event, reduce the size again.

In other words: Each click on the DIV element toggles its size.
