$HTTP_POST_VARS

Hi...I'm just wondering if anyone had any idea on how to assign all the variables grabbed from $HTTP_POST_VARS to their own variables?

i.e $HTTP_POST_VARS['action'] would simply be called $action.

The reason I need to do this, is because it seems that some servers have a weird security feature installed, whereas they won't let you call variables like $action Frown

At the moment I have this code;

Code:
foreach($HTTP_POST_VARS as $thing => $var) { 

  $$thing = $HTTP_POST_VARS[$var]; 
  echo "assigning \$$thing to $var <BR>"; 

}

Now, that doesn't seem to be working right, in assigning the variables.

Has anyone ever had to do this, and if so, would you mind sharing how?

Cheers

Never mind....turned out I needed to use $HTTP_GET_VARS...

Code:
// make sure we grab the variables we need...otherwise some servers will spew :D 
foreach($HTTP_GET_VARS as $thing => $var) { 
  $$thing = $var; 
} 

foreach($HTTP_POST_VARS as $thing => $var) { 
  $$thing = $var; 
}

I used both $HTTP_POST_VARS and $HTTP_GET_VARS, assigning both their own variables...

It's called register_globals and is off by default now on new phps:

http://www.php.net/....registerglobals.php

Re: [Andy] $HTTP_POST_VARS In reply to

If you do a lot of PHP work, you really should read over the WHOLE PHP manual; it's extremely useful, and you'll be surprised what things you'll find. If you did, you would have seen that there's an 'extract' function: http://php.net/extract.

Why are you doing this anyways? Having all post variables as globals isn't such a good idea (except for convenience).

Yeah, but its finding the time to read through the whole manual Wink

Re why I need them as globals...

It was simply the fact I had writen the script thinking that all versions of PHP 4+ would use;

$var_name

rather than

$HTTP_POST_VARS['var_name'].

It worked on my server, and pretty much all the servers I tried it on....but I thought i would make some code up to assign non-array variables, so I dind't have to go through all 50 files, and update all the variable calls Tongue

Thanks guys
