How do I get my file to get the current URL (that is being viewed), parse it and display only the variable to the page?

echo $_SERVER['REQUEST_URI'];
that'll output the current top document request call (query string included)
next bit...
just output the variable ? or the value of the variable ?
foreach($_GET as $var=>$val)
{
echo $var.'<br />';
}
well, that's the get variables echoed. If you didn't mean that, please explain better.

$_SERVER['QUERY_STRING'] might be what you're looking for - or the $_GET array, as mentioned above.
See php manual "predefined variables" for full info.
Re the code above:
Code: Select all
foreach($_GET as $var=>$val)
{
echo $var.'<br />';
}
Isn't that just echoing out the keys?
If you want to declare the vars (you might not need to) try:
Code: Select all
foreach($_GET as $var=>$val)
{
$$var = $val;
}
You might want to do some processing on GET vars for security reasons but I'm still figuring that out.
