How to check if php://input is set?

Question

I need to check if php://input exists/isset. Does it work with php isset() ? What is the proper way to check it?

Answer 1

You can get the contents of php://input using file_get_contents and check the return value to see if it's actually set:

$input = file_get_contents("php://input");
if ($input) {    
    // set     
}
else {
   // not set
}
