global variables

Anon

Hi all I have what may or may not be a simple question.

I need to pass $HTTP_POST_VARS to a function.

Within this function I have a include statement and the code that is loaded I wish for it to be able to reference the variables just like you normally would from a posted form.

class runtime{
function execute($handler,$vars){
//need vars to be globally available here
include($handler); //needs the $vars
}
}

$cls = new runtime()
$cls->execute($handler,$HTTP_POST_VARS)

umm..i'm fairly new to PHP but I think you can avoid passing in the $HTTP_POST_VARS

I think you can (within function) type:

global $HTTP_POST_VARS

and then you can reference them as if local

Anon

This is possible.
You could also pass the $HTTP_POST_VARS as a parameter.

i can't help feeling that environment variables ($HTTP_POST_VARS, $PHP_SELF and so forth) should be global by default.

what do people think?

THay can be global if you want them to, but who'd want to?

Using the HTTP_POST_VARS you allways know that whatever is in there came from a http post action.
Otherwise you'd end up giving your vars names like name_from_form and email_from_form.

Well let me rephrase the question just a little. The include file that I mention has this in it.
<pre>

<?
echo($formvar);
?>

</pre>

So what I am really talking about doing here is dynamically creating the variables so that the include file does nothing special to grab the form variables. I wish for it to appear as though the include was posted to not the original function.

This is kind of hard to explain correctly and I do have a good reason for doing this. Thanx for the help Cliff

If you use an include() then all variables in the main program are also available in the included file.

So if you can use $HTTP_POST_VARS[] in the main program, you can also use it in the included file.

if you use a real function; like

function myfunction($a,$b)
{

do mystuff

then you must pass the HTTP_POST_VARS as an argument.

Yes but I do not wish to reference using HTTP_POST_VARS. I need to pass that into the class and at that point I need to recreate the variables in the execution space so that they can be referenced just as if the included code was the one posted to by the form. So is there a way to loop thru the variable list creating them dynamically thus allowing the included code to reference the variables just as if PHP did it for me. You see the function will never know the variable list passed to it ahead of time since many forms may post to it.

Thanx for the help everyone but I finally found the solution to the problem in my professional php programming book.

In order to dynamically create variables from a passed in array you can run the following.

<PRE>
/ recreate all variables on the stack as passed by http_post_vars or $http_get_vars /
if (isset($vars)){
while (list ($key, $val) = each ($vars)) {
$newvar = "$key";
$$newvar = $val;
}
}
</PRE>

Simple but it sure kicked my but finding the solution.
