RE: [PHP] '<?=' History / Info request

<? ?> Is for short tags, you should use <?php ?> to be totally compliant with all web servers. ="xxx"; essentially means echo so <?='history ...'?> will echo history... I think you're confusing two seperate things as one thing. Use <?php ?> for code start / end use ='xxx'; or echo 'xxx'; if you're feeling lazy Personally I wouldn't use the ='xxx'; style, because its not as readable, and not everyone knows it. If you work with other people, its good to make code as readable as possible. saving 4 keystrokes isn't really a saving in the long term. Perl hackers may disagree here, but hey, I think some of my perl stuff looks like line noise after i've written it! -----Original Message----- From: Philip Olson [mailto:philip@theprojects.org] Sent: November 17, 2000 11:28 AM To: php-general@lists.php.net Subject: [PHP] '<?=' History / Info request Hi! I do not use this <?= because I know not all accept its use but *who* doesn't? Thus far I find some information but only through humans, no docs : Warning : Assumptions are just that, assumptions. Fairly certain they are true but ... not 100% sure. Assumptions : ------------- A. PHP4 Specific. B. If short_open_tag = 'off' in php.ini then this short cut is disabled C. It acts as echo , not print Questions : ------------- A. What version did this come about exactly, 4.0.0 ? B. What are some reasons one would disable short tags? C. Is there a way to bypass a short tags setting so that it'll work, like in an included config file? .htaccess is fine but ideally a check like 'if short tags off then enable short tags.' although i suppose this would defeat the purpose of 'off'. Hmm. D. Could this "bypass" easily be done on php3 parsers as well? I assume no way but will ask anyways as I am paranoid. Can think of ways to 'convert' but they involve work. Boo work. Comments : ------------- AFAIK this is not mentioned anywhere in the manual but of course should be. I found reference to the ASP style shortcut of <%= but not this. Also, <?= is not mentioned as a short tag in short tag settings. I understand this is no doubt on the TODO list to document but I am curious now! Would be nice if more time existed, bah, stupid time :-) References : ------------- Should be mentioned here as a short tag for echo , as well as in default php.ini setting : - http://www.php.net/manual/configuration.php#ini.short-open-tag Briefly mentions <%= (ASP Style) but not <?= (PHP Style) but should : - http://www.php.net/manual/language.basic-syntax.php If a short cut for echo() it may as well be mentioned here too: - http://www.php.net/manual/function.echo.php Can't find mention in changelogs : - PHP4 : http://php.net/ChangeLog-4.php - PHP3 : http://php.net/ChangeLog.php3 Thank you, with this cleared up perhaps I, along with others, will use this -- when applicable.
