(only) the reason that is given on the "Continue with missing semikolon" example is wrong.
the script will output "2" because the missing semikolon causes that the
"print"-call is executed only if the "if" statement is true. It has nothing to
to with "what" the "print"-call would return or not return, but the returning
value can cause to skip to the end of higher level Loops if any call is used that will return a
bigger number than 1.
<?php
continue print "$i\n";
?>
because of the optional argument, the script will not run into a "unexpected T_PRINT"
error. It will not run into an error, too, if the call after continue does return anything but a
number.
i suggest to change it from:
because the return value of the print() call is int(1), and it will look like the optional numeric
argument mentioned above.
to
because the print() call will look like the optional numeric argument mentioned above.
