   // substr() shouldn't work on integers.
   // the first argument is first converted to string, and it is 123456.
   echo substr(123456, 0, 4); // display 1234
   
   // substr() shouldn't work on boolean
   // the first argument is first converted to string, and it is 1, and not t
   echo substr(true, 0, 1); // displays 1
