Const arrays is very useful thing! For example when storing error codes
etc.



Why isn't it possible just to fix the behavior?

This bug has been fixed in CVS.

Thank you for the report, and for helping us make PHP better.

Arrays in class constants aren't allowed anymore.

This isn't restricted to associative arrays in which keys are
explicitly specified:



class f { const t = array(7,6,5); }

echo f::t[1];

------------------------------------------------------------------------

This is an easier verification:

php -r 'class t{const c=array(1=>"Hello\n");} echo t::c[1];'

The parse error thrown complains about the print(someData['foo']) line.
Sorry if this wasn't clear. Also expected output would probably be more
like "bar ..var_dump output.. bar.

Description:
------------
Constants defined inside classes can be defined as an array
prepopulated with key, value pairs; however this data is not directly
accessible.



It is possible to create a local variable copy of the constant at
runtime and use it to access the data.



If class constants are not meant to be able to hold array data, then a
parse error should of been thrown on the 'const' declaration.

Reproduce code:
---------------
class test {

  const someData = array('foo' => 'bar');



  function __construct() {

    $dataCopy = someData;

    print($dataCopy['foo']);  // This works

    print(var_dump(someData));  // This works (shows all array
information)

    print(someData['foo']);  // This throws a parse error

  }



}



$obj = new test();

Expected result:
----------------
bar

bar

bar



.. Jackpot! :)

Actual result:
--------------
Parse error: parse error, unexpected '[' 


------------------------------------------------------------------------
