If you really *must* do this yourself (but others have pointed out the folly of it), this would do it:
function value2var($array)
{
foreach ($array as $key => $value)
{
$GLOBALS['$key'] = $value;
}
}
What's the sense in above function? you're putting the variables from
1 array in another...
you could use array_merge for this.
But even then it's quite useless...
... or, alternatively, rather than defining you own function, use extract() (http://php.net/extract) with one of the overwrite safety options to avoid blobbing existing variables.
That's a better idea. :)
Personally, I'd never do this in any form -- if I do it at all, I extract specific indices of the array with code like:
foreach (array('name', 'address', 'email', 'setting1', 'setting2') as $key):
$GLOBALS[$key] = $array[$key];
endforeach;
endforeach? never heard of that statement before, does it really exist in PHP?
... making certain, of course, that those values get properly validated elsewhere.
Cheers!

Sure, you should always validate your variables, but i would recommend
to only get the variables from $_GET/$_POST that you actually gonna
need, and not just everything.
