I'm currently browsing issues for Zend PHP 5 Certification Practice Test and saw the following:
print print('5') + print('4');
// output
// 461
// or
echo '3' + '0.5' , print('2') + 1;
// output
// 3.531
How does it work? Description and examples from http://php.net/manual/en/function.print.php did not clarify anything…
