This RFC will discuss an language enhancement for simple and easy array definition.
Another solution would be to implement named parameters.
Ryusuke 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 / Contra
Pro and contra arguments that were derived from the list.
- Good for framework development when dealing with long parameterlists
- Other web languages have similar syntax
- Yet another alias
- Would take distinctness from 
- Not searchable through search engines
- Patch may be difficult to maintain in future
This patch will not be accepted because slight majority of the core developers voted against. Though if you take a accumulated mean between core developers and userland votes seems to show the opposite it would be irresponsible to submit a patch witch is not supported or maintained in the long run.
