This is not a valid PHP statement.
The ' directly before 'text text text text' will match the first ', and
the rest of this is gibberish.
Let's assume, however, that you actually have \ in front of each embedded
' in your string.
To avoid confusion, I'd also change each \$ to \\$ so that it is clear
that you want the \ to be embedded in your string.

At this point, you are replacing HTML entities < and > with their
corresponding charactes < and > which is fine, I suppose, but...

Here you are *NOT* going to see the PHP source, because to the *BROWSER*
the < and > look like an HTML tag.
The browsers will simply IGNORE tags they don't understand and won't
display/do anything with them.

You may or may not need to NOT do the ereg_replace you are doing, and you
may or may not want to use http://php.net/htmlentities and/or
http://php.net/highlight_string
