I get asked quite often if there is a way to show CODE on a website, with it’s formatting in place?
The short answer is <pre>
It can output free text (i.e. non server side code) in a pre-formatted way. Yep, PRE = Pre-formatted.
On top of that, Preformatted also renders the php print_r() output in a nicely nested unordered list, which is great for debug purposes;
e.g.
[sourcecode language=’php’] echo ”
"; print_r($arr); echo "
“; [/sourcecode]
I am sure there are other uses for the <pre> tag too, I have just scratched the surface.
Give it a go – let me know if you find other uses for it.
Thanks.
