drcru posted:Does anyone have any idea on how to efficiently create a random maze via PHP? A much faster maze generation algorithm is Eller's algorithm. The mazes might not be quite as pretty or have as nice properties, but it is perfect, and it's easy to do efficiently-- I used it to do maze generation in TI-89 BASIC, using only a few single-dimensional arrays and integers. The idea is that you generate and output the maze one line at a time-- there's a good summary at http://www.astrolog.org/labyrnth/algrithm.htm (Ctrl-F Eller)  The mazes are pretty good if you tweak it properly.

drcru posted:So would you add a salt before and after? If you want to be paranoid-- generate ~16 random bytes for salt hash salt . password do another ~100 rounds of hashing on the result store the salt + hash in the database This will make bruteforcing really slow, and rainbow tables impractical.

IT Guy posted:Am I doing this wrong? If you're okay with XHTML instead of HTML, use XMLWriter instead. It's stream-based, so your code ends up looking a lot nicer: php:<?
$w=new XMLWriter();
$w->openMemory();
$w->startDocument('1.0','UTF-8');
$w->startElement("root");
$w->writeAttribute("ah", "OK");
$w->text('Wow, it works!');
$w->endElement();
echo $w->outputMemory(true);
?>
