preg instead of ereg, and then you need
PCRE support in PHP. Or you could use ereg's character classes, I think the

there's \r's as well as \n's in the string. Try this:

syntax features and language constructs which can significantly
improve code performance and manageability -- use them!
Now this code could easily be extended to give each state a descriptive
name, and to create a generic listbox-drawing function which you can then
re-use elsewhere in your program (o
rror), because there is no
index matching "donkey" (the value of the constant "foo"). But for some
reason PHP looks for an array index matching the string "foo" as well,
encouraging this kind of sloppy programming.

I'm not actually sure what the override setting you need is, but you could
try Options or just All.
http://httpd.apache.org/docs/mod/core.html#allowoverride
Example:
AllowOverride All

Of course, if you're able to edit httpd.conf then you could just put
</a>
Which should render as a link, followed by a textarea with the HTML code for
that link. If you want the first link to render as code as well then you
need to run it through htmlspecialchars() too.

That should work but imho better practice is to use getenv():
This is especially useful inside a function, a
echo $encodedstring;
// Will output: foo%3Dbar%26food%3Dapple
If "bar" and "apple" were variables, you would rather urlencode() them
individually.
