There are specific classes and functions in the PHP core that can help
you do just this.

I don't think this is the right approach to take. Maybe using the DOM
and/or the XML Parser built-in to php would help you.

Again, this isn't the approach to take. There are built-in functions
for this sort of thing, as well as classes on PEAR that will help you.
Try google!
Read through all of this and decide which approach you want to take
before you start anything...
If you use Windows or compile PHP as an Apache module in Linux, you're
all set with the XML Parser. If not, you'll need to get the library
according to the directions in the manual.
http://www.php.net/xml
Read everything in that thoroughly, and understand it before you
continue with this approach. Copy and play with the examples to see
how it all works. If you'd rather handle things in an environment
designed to create and manipulate XML dynamically, rather than just
read and insert raw strings, keep reading.
You can get the DOM XML working easily in Windows, and even easier in
a GNOME environment on a linux box. The manual has excellent
instructions.
http://www.php.net/domxml
This extension is Object-Oriented (OO), and if you don't know what
that is, you better read up on it before you try this out. If you do,
and have an OK understanding of how OO works in PHP, then read on! If
not, read the article....
http://www.php.net/oop
Now, understand that DOM XML is very particular about the syntax and
such in an XML file. The file MUST start with the XML declaration
(without quotes) "<?xml version=1.0>" in order for DOM to try and use
it.
Use the functions to read right through it all. You'll find that this
is probably exactly what you need!
I'd use DOM XML personally. I included the other in case you didn't
want to have to install everything.
Have fun, and good luck with PHP!

I upgraded to PHP 5.0.4 and now all my downloads cut off at 1.9 MB
Is this a setting I missed somewhere?

Hi,
Has anyone got the DOM extension to load compressed XML transparently?
libxml2 apparently has this feature, but it appears not present in PHP
build.

Thanks for the info, but do I create the form in front page then? Where
does this script go? Do I save the php you sent as a results page?
thanks,

Can anyone help with a statement, ive tried but it never works.
I need to show a value if it is set to a specific value ie:
At the moment If a user is logs in a record is updated from 'away' to
'online'---so i want an echo statement to show a value from another table if
they are set to online or else they show another value.
(2 seperate tables).

Big difference. :-)
Well it's not a standard trail account. One of the owners offered me to
try it for a month to see if it suited me. My domain is moved to them
and everything.. so it's probably treated as any other account. And it's
not exactly budget hosting either......
.htaccess off also gives a performance boost they might not be willing to
forego, even if it were possible.
.htaccess is not off, just the php_flag/php_value

not a php expert but have filed this bug report re validating
is_numeric('3e0');
http://bugs.php.net/bug.php?id=32943

function isnumeric($n) {
if (ereg("^[0-9]{1,50}.?[0-9]{0,50}$", $n)) {
return true;
} else {
return false;
}
}
and that doent seem to work either..
