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

Suppose you are getting user input from a POST request you can check if it's a set like this

 if(isset($_POST['var_name']))
 {
      //for additional checking  like if  it's not  empty do this
      if(!empty($_POST['var_name']))
      {
           //Do whatever you want here
      }
 }
