This RFC will discuss an language enhancement for simple and easy array definition.
Update: May 2011This topic has come up again on the list.
IntroductionIn some cases it is necessary that you have to pass function parameters as an array. Especially when you work with nested arrays the php array function tends to make the code looking ugly. If you take a look at other languages (Ruby, Python, Javascript) there is a short syntax for arrays using square brackets. Maybe PHP should adopt this behaviour to make code more readable and maintainable.
Another solution would be to implement named parameters.
SyntaxRyusuke suggested two possibly syntaxes and also provides two patches for a solution:
Square bracket array shortcut - keys and values are separated by colons:
$a = [1, 2, 3];
$b = ['foo': 'orange', 'bar': 'apple', 'baz': 'lemon'];
Square bracket array shortcut - keys and values are separated by double arrows:
$a = [1, 2, 3];
$b = ['foo' => 'orange', 'bar' => 'apple', 'baz' => 'lemon']; Proposal and Patch
The first solution is more compact: http://www.opendogs.org/pub/php-5.3dev-080109-sbar.patch
The second solution is more “The PHP Way”: http://www.opendogs.org/pub/php-5.3dev-080109-sbar2.patch
Pro and contra arguments that were derived from the list.
ProGood for framework development when dealing with long parameterlists
Other web languages have similar syntax
Readable
Yet another alias
Would take distinctness from []
Not searchable through search engines
Unreadable
Patch may be difficult to maintain in future
This patch has been merged in PHP 5.4.0 and trunk.
