Do PHP webpage effect optimization

All of my pages are in HTM format, however I am considering changing some if not all to PHP or ASPX. Will this effect optimization on Google or does it make no difference.

 

Shouldn't make a difference.

 

It will not make a difference in how well your pages can rank, however, I suggest using a URL re-writing solution to ease the transfer and make it transparent to Google.

 

thank you for your reply

 

You may want to look at the coding for your signature block. I believe you would rather have:

Data Recovery, Server Data Recovery, Fields Data Recovery

 

I would rather that but how

 

I think I have go it right now, thanx

 

I found that the SEs don't like to index dynamic pages. You can hide that your pages are dynamic (if your server is running Apache) by formatting the pages as:
http://www.mysite.com/filename.php/parm/value/parm2/value2 and using this bit of code:
if (strlen($_SERVER['PATH_INFO']) > 1) {
$vars = explode('/', substr($_SERVER['PATH_INFO'], 1));
while (list(, $var) = each($vars)) {
list(, $val) = each($vars);
$HTTP_GET_VARS[$var] = $val;
$_GET[$var] = $val;
$GLOBALS[$var] = $val;
}
}

What is does is to create variables in the global namespace, $_GET and $HTTP_GET_VARS arrays with the variables on the directory list. So in my example, you'd get $_GET['parm'],$_GET['parm1'], $HTTP_GET_VARS['parm'], $HTTP_GET_VARS['parm1'],$parm, and $parm1 all set.

This only works in Apache, because Apache will walk up the path until it finds a file. It also must be in the mainline code and not in a function -- at least not unless you use the global keyword on the vars.
