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;
}
}
... 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.
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;
... making certain, of course, that those values get properly validated
elsewhere.
Cheers!
