A concise way for PHP to use Post,get _php tips

Recently saw a clever way, the principle is
$var _a = ' var_b ';
$ $var _a = ' Test ';
echo $var _b;
So it can be handled like this

Copy Code code as follows:

foreach (Array (' _cookie ', ' _post ', ' _get ') as $_request)
{
foreach ($$_request as $_key => $_value)
{
$_key{0}!= ' _ ' && $$_key = addslashes ($_value);
}
}

It looks like test.php?name=name_in&pwd=pwd_in.
You can just use $name, $pwd
To reference the data sent by the client.
Note: The variables sent by the customer are filtered using addslashes ().
