Here is a copy of what Dennis had written to me regarding automatic implementations from C# (the model):
> Originally, C# did not support automatically implemented properties. > There are several reasons why they were added. The first reason, is that > while the syntax for properties is the same as the syntax for member > variables, there is still some subtle differences in behaviour that cannot be > accounted for by properties. Here are some examples: > - Variables may be used as input to out/ref arguments. Properties may not. > - Properties may throw exceptions - variables will never do that. > - Properties may have side effects or take a really long time to execute. > Variables have no side effects and will always be as fast as can be expected > for the given type. > - Properties support different accessibility - variables do not > - When using reflection the properties and fields are treated as different > MemberTypes so are located differently (GetFields vs GetProperties for example) Some of these above example still apply (reflection, execution time), so the automatic implementations may simply be there as a way for authors to indicate their intention to make them execute code at a later time. This suggestion below shortens the syntax even further. -----Original Message----- From: Stas Malyshev [mailto:smalys...@sugarcrm.com] Sent: Tuesday, April 24, 2012 12:11 PM To: Benjamin Eberlei Cc: internals@lists.php.net Subject: Re: [PHP-DEV] RFC: Property get/set syntax (added isset/unset and references) Hi! > would it be possible to add a second shorthand syntax to the complete > automatic implementation? > > Examples: > > class TimePeriod > { > public $Hours {}; > public property $Hours; > public $Hours {property}; > } How it is different from just public $Hours and why one would need this? -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
