# 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:

Пример D-5. Migration: old if..endif syntax
`if ($foo); echo "yep\n"; elseif ($bar); echo "almost\n"; else; echo "nope\n"; endif;`

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Notice that the semicolons have been replaced by colons in all statements but the one terminating the expression (endif).
