PHP 7 - New features

Scalar type declarations

Scalar type declarations come in two flavours: coercive (default) and strict. The following types for parameters can now be enforced (either coercively or strictly): strings (string), integers (int), floating-point numbers (float), and booleans (bool). They augment the other types introduced in PHP 5: class names, interfaces, array and callable.

// Coercive mode
function sumOfInts(int ...$ints)
{
    return array_sum($ints);
}

var_dump(sumOfInts(2, '3', 4.1));

  1. // function with 2 optional arguments  
  2. function foo($arg1 = '', $arg2 = '') {  
  3.   
  4.     echo "arg1: $arg1n";  
  5.     echo "arg2: $arg2n";  
  6.   
  7. }  
  8.   
  9. foo('hello','world');  
  10. /* s: 
  11. arg1: hello 
  12. arg2: world
