Question

Can anyone please explain to me how this works:

<?php
    print 5 . print 6 . print 7;
?>

it prints: 76151

I know the 1 is the return value from the print function, but why are the functions called in reverse order?

Answer 1

I believe this occurs because the dot operator is left-associative.

The expression would look like this with parenthesis:

print 5 . (print 6 . (print 7));
