In some examples above the following snipplet is being used:
reset ($HTTP_POST_VARS);
while (list ($key, $val) = each ($HTTP_POST_VARS)) {
//do something crazy with the $val
eval("\$" . "\$key = \"$val\";");
}
Actually you don't need eval to do this!
Remember that PHP has this already built in.
Just use this snipplet:
reset ($_POST);
while (list($key,$val) = each($_POST))
{
$$key = $val;
}
The '$$' does the job! HTH
