Right. However, I wouldn't want to encourage anyone to use this mixed style. Given that this request is more than ten years old and got almost no traction, I'm closing as WONTFIX. If you, or anybody else for that matter, is still interested in this, please pursue the RFC process[1]. > It should be improved to specify what happens e.g. in the > following dangling else case: Done[2].

PHP should work like most other languages: an else should always be associated with the nearest previous if statement. Period. Any other behavior can be obtained by using curly brackets. 2. Currently, the PHP Manual is incomplete in describing valid sequences of nested ifs, thens, and elses. It should be improved to specify what happens e.g. in the following dangling else case: if ($a) if ($b) b(); else c(); Of course, the "else c();" should be associated with "if ($b) b();". 3. Colons following if, then, or else tokens should result in a syntax error. 4. "elseif" or "elif" (your choice) should be a valid abbreviation for "else if". ------------------------------------------------------------------------ [2010-02-11 14:03:44] claude dot pache at gmail dot com Description: ------------ In case of ambiguity, the statements "else" and "elseif" are always associated to the last previous "if" or "elseif". This rule is not convenable when the else/elseif is followed by a colon and the last previous if/elseif is not. See also: http://bugs.php.net/bug.php?id=838 Reproduce code: --------------- if(foo): // some code here if (bar) baz; else: // some code here endif; Expected result: ---------------- Since the "else" is followed by a colon (:), it can be associated *unambiguously* with the last "if" followed by a colon (here, "if(foo):"), and not with the last "if" (here, "if(bar)"). Actual result: -------------- Parse error. The "else" is associated with the last "if", and the following ":" is unexpected. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=51016&edit=1
