Hi Shoan
It's no problem at all.
The PHP variable $_SERVER['QUERY_STRING'] (which I think used to be
$HTTP_SERVER_VARS['QUERY_STRING'] in older versions of PHP) refers all
of the text following a '?' character in a URL.
For example, in
"http://cgi.ppltd.plus.com/php/precision/precision.php?index_body.htm&TB=1";
the query string reads as "index_body.htm&TB=1".
In this case it is used to tell the "precision.php" script to include
the file "index_body.htm" after the HTML code embedded in itself that
displays the headings common to all of the pages on the site.
It also tells the new "instance" of 'precision.php' that the Tab 1 in
the Tab View is the currently selected one.
'precision.php' then highlights the first tab when it builds the
"header" section of the page is highlighted and the contents of the rest
of the page is read word for word from the HTML snippet in "index_body.htm".
Exploding the QUERY_STRING using '&', creates an array of two strings,
"index_body.htm" and "TB=1".
In the 'precision.php' script, I just look for the string that doesn't
contain "TB=" and include the HTM file named in the other string.
I did it that way so that the order in which the query string elements
didn't matter.
As far as the client browser is concerned, the HTML code in
'index_body.htm' is output as if it seamlessly followed the HTML code in
the PHP embedded header.
It means that if I amend the page header HTML code embedded in the PHP
script it will automatically apply to all of the pages in the site.
I only have one copy of the "body" of each page as an HTML snippet.
I don't have to use frames to get this effect as search engines
generally don't like frames.
To see it in action take a look at www.precisionproductions.com.
If it still doesn't make sense, I can post a full working example on my
website in a few hours time.
Best wishes
