I am moving my web site to a new host this weekend. I am working
towards making the code compatible to the structure of the new server.
I am getting a weird response which I don't understand
At the very start of my index.php I have the following lines of code:
foreach($_GET as $key => $val) {
$$key = $_GET[$val];
echo $_GET[$val] . "<br />";
}
What I don't understand is why the output is
<br /><br />
I am not understanding how two "empty" variables are being passed.
index.php is driven off of various mod re-writes contained
within .htaccess . This is why I am doing the loop above.
RewriteRule ^page/([^/\.]+)/?$ index.php?page=$1 [L]
RewriteRule ^page/([^/\.]+)/([^/\.]+)/?$ index.php?page=$1&field1=$2 [L]
RewriteRule ^page/([^/\.]+)/([^/\.]+)/([^/\.]+)/?$ index.php?page=
$1&field1=$2&field2=$3 [L]
What should I be trying? What will allow the value of page to be passed
onto $page with the following URL:

Try:
echo $_GET[$key] . "<br />";

For future reference, the general practice on the list is not even
to acknowledge the email.

I normally have a prep4display() and prep4store() type function that do
all of the sensitization/prep for either storing or displaying. So
prep4display() has a check for magic_quotes_gpc for which it does
stripslashes() if they are on and then htmlentities() etc.. and the
prep4store() can do mysql_real_escape_string() and whatever else.

Well, since this last post didn't make a whole lot of sense I thought
I'd clarify and add a little. So I use the prep4display() in an echo or
when building display output and prep4store() in a query etc.
The addition that I find useful sometimes are clean_from_input() and
clean_for_output() type functions which may use the aforementioned ones.
clean_from_input() you can call like clean_from_input('some_getvar')
and it will check to see if the $_GET var (or more generally $_REQUEST
or $_GET || $_POST) is set and return after stripping slashes if
magic_quotes_gpc is set and whatever else. Then the clean_for_output()
does some stuff for output when you need it. My point is that if you
build a function to retrieve get/post/cookie vars etc, then you can
clean it however you want and also build in the isset() stuff there so
it returns '' or false, etc... and you don't have all kinds of isset()
or !empty() calls in your main code.
So build some general purpose functions or methods that scrub input and
prep output and try and get it to handle as many cases as possible.
Then use those functions.

If I remove the \r from the file using preg_replace() then it shows up just
fine. I was just wondering if there was a way to suppress the \r in the xml
output.
Another thing that I've observed while looking at your code is that it only
works best for dynamic web pages. It appears that it would not work well when
using page caching or page templates.
I really think having a function that generates xhtml (html compatible) output,
would really eliminate all these workarounds that we will have to do in order
to get the page to render inside popular web browsers.
A lot of developers produce xhtml web pages that are html 4 compatible, so that
they can be rendered in browsers that only supports html rendering. This is
something that I think the PHP DOM should be able to support with ease.
Best regards,

A lot of developers produce xhtml web pages that are html 4 compatible, so that
they can be rendered in browsers that only supports html rendering. This is
something that I think the PHP DOM should be able to support with ease.
If you want to send the same page for everybody than use html 4.01 (or
html 5 when it is ready) and the saveHTML() function.
The only reason I don't do that is because I wish html would go away, so
I generally send valid xhtml (header and all) and only provide the html
as a fall back for inferior browsers.
With respect to templating systems, I don't use them but if you have a
DOMDocument orientated template system, I don't see why it couldn't do
the same thing - as far as the DOM used to generate xhtml (via
saveXML()) or html (via saveHTML()) - the only difference is the DTD and
the fact that xhtml sometimes uses namespaced attributes (which may get
stripped with saveHTML() anyway)
That's the beauty IMHO of DOMDocument - virtually identical data in the
DOM can produce valid html or xhtml - as long as you aren't using xhtml
only extensions (like MathML).
So it should work beautifully with a templating system, as long as the
templating system is built for DOMDocument consumption.
I think there are a few.
How well they work with caching I don't know.

As an experiment, I took one of my pages that was a little sluggish due
to lots of database calls (sluggish on my home machine anyway) - since
the database content rarely changes for the data presented, I made a
page I can grab nightly in cron that spits out just the main content div
where all the DB calls are made.
-=-
$cached = 'species_cache.php';
$SL = file_get_contents($cached);
$SDOM = new DOMDocument("1.0","UTF-8");
$SDOM->loadXML($SL);
$elements = $SDOM->getElementsByTagName("div");
$imported_div = $elements->item(0);
$contentDiv = $myxhtml->importNode($imported_div,true);
-=-
species_cache.php
is just a text file with a div and all it's children.
Sped up the page considerably on my home machine, and works spledidly
regardless of whether or not I am sending it as html or xhtml.
So I think my technique would work with template systems.

I've run into a small issue with mdb2.
I have a mysql database with a field set to longtext not null.
inserting "" into that field works just dandy when using the mysql_
functions.
However, when using mdb2 - it converts "" to NULL which is NOT what I
want to have happen, and the result is that the execute() fails because
the database table does not accept NULL for that field.
Why does mdb2 turn "" into NULL for a text type when MySQL knows there
is a difference? How do I suppress that?

Why not set a default in the field then, as am empty string and let
the db handle field properly? Having a Not Null with no default is bad
db design.

I can confirm the presence of the same issue on my installation, 5.2.9-2 on
Windows XP. Very annoying bug.
