which CMS software is better?

[MyDigitalpoint]

It's supposed nobody can see your PHP source unless you are expressly adding the means to allow people see the source in a text-friendly manner.

However I remember that several years back there were a couple of websites out there promising to reveal you any PHP source from the web. I was newbie at coding so I simply test an URL to see, and it revealed me the PHP source on it, in fact it was an IPB 1.3 index page that I later was able to compare with the real file when I downloaded such script.

Sometime later I found that script in SourceForge.net and tried it on my own, but eventually I lost it and it was deleted from that place. I suppose due to security breach, despite I can't still understand how that code worked.

Perhap a flaw in old PHP versions too.
