Crappy the pagerank spider v.1.00

Crappy the Pagerank Spider, v1.00

The very simple version, this one has some minor hick-up’s. It spiders and you can have it compose a google sitemap and a rudimentary pagerank map (I haven’t programmed it to handle www.domain.com/ as www.domain.com/index.doc).

It however works brilliant for indicating leaks in wordpress themes and other mayhem and mischief.

At the core : the pagerank calculation

for each file (node)
    for each link-in to a file
        take the in-linking file's value
        divide that value by the linking file's outbound links
        add it
sum-of-additions = the new node value

Iterate 30 times, for each node, and you’re quite close to a realistic pagerank distribution map.

for($ii=0;$ii<30;$ii++) {
foreach($this->MyFiles as $Fl) {
foreach($Fl->MyLinksIn as $Li) {
$In = $this->MyFiles($Li->url)->Value;
$InT = $this->MyFiles($Li->url)->LinkOutCount;
$val = $val + $In / $InT;
}
$Fl->Value = .15 + .85 * $val;
$val=0;
}
}

So for the calculation I need :

a files-class with a collection LinksIn, LinksOut, and a variable for Value and LinkOut.Count.
a class LinkIn
a class LinkOut
a spider function to grab the files and links

(i ditched the code listing, the echoed tables and linebreaks break my layout)

then there are the real goodies :
