Can anyone explain what the $$ sign does.😕
Here is the code it's used in
foreach($_POST as $field => $value) #134
{
if($field != "Button")
{
if($field == "password")
{
$password = strip_tags(trim($value));
}
else
{
$fields[]=$field;
$value = strip_tags(trim($value));
$values[]=addslashes($value);
$$field = $value; // what does this line do??
}
}
Have tried google but nothing specific came up.
