Python-like tuple unpacking for PHP

Python provides a neat way for functions to return multiple arguments via “tuple unpacking”. For example:

def blah:
  return ('one', 'two')

rval_1, rval_2 = blah()

The same can be done in PHP relatively easily via the list construct:

function blah()
{
  return array('one', 'two');
}

list($rval_1, $rval_2) = blah();
