A simple way to use post and get in php_PHP tutorial

Recently I saw a clever method, the principle is
$var_a ='var_b';
$$var_a ='test';
then echo $var_b; is 'test'
so it can be handled like this

Copy code The code is as follows:

foreach(array('_COOKIE', '_POST', '_GET') as $ _request)
{
foreach($$_request as $_key => $_value)
{
$_key{0} != '_' && $$_key = addslashes($_value) ;
　}
}

Like test.php?name=name_in&pwd=pwd_in
you can directly use $name, $pwd
to quote the client to send data.
Note: The variables sent by the customer are filtered here using addslashes().
