if..endif syntax
The `alternative' way to write if/elseif/else
statements, using if(); elseif(); else; endif; cannot be
efficiently implemented without adding a large amount of
complexity to the 3.0 parser. Because of this, the syntax has
been changed:
範例 C-5. Migration: old if..endif syntax
if ($foo);
echo "yep\n";
elseif ($bar);
echo "almost\n";
else;
echo "nope\n";
endif;

範例 C-6. Migration: new if..endif syntax
if ($foo):
echo "yep\n";
elseif ($bar):
echo "almost\n";
else:
echo "nope\n";
endif;
|

Notice that the semicolons have been replaced by colons in
all statements but the one terminating the expression
(endif).
