将String true / false转换为整数值

Question

I'm getting true or false from query string i don't have access to change this www.example.com?is_test=true

But in backend for database i'm excepting integer like 0,1

To achieve this i'm trying like this

(int) (boolean) 'true' //gives 1
(int) (boolean) 'false' //gives 1 but i need 0 here

Event i tried

$test = "false";
$bool = settype($test, 'boolean'); //it was giving true

(int) $bool also gives 1

i'm not sure there might be some other better php function to achieve this? Or any better way to this please suggest

Yah ternary operator is one best option But is there any other options for conversion

Answer 1

PHP can't read your strings. You'll have to use some kind of if-else construction:

if ($GET['is_test'] === 'false') {
    return 0;
} else {
    return 1;
}
