Syntax error when defining an array as a class property

Question

...

public $aSettings = array(
  'BindHost' => "127.0.0.1",
  'Port' => 9123,
  'MaxFileSize' => (5 * (1024 * 1024)), // unexpected "(" here
  'UploadedURL' => "http://localhost",
  'UploadPath' => dirname(__FILE__) . "/upload",
  'UploadMap' => dirname(__FILE__) . "/uploads.object",
  'RegisterMode' => false
);

...

This is my code, right from the class. I have a problem:, "unexpected ( on line 22"line 22 - MaxFileSize.

I don't see a problem with this, is this a limitation of Zend Engine? Or I'm blind.

Answer 1

You cannot use inconsistent values ​​when initializing class properties in PHP versions earlier than 5.6.
They are initialized at compile time, in which PHP will not perform any calculations or execute any code. (5 * (1024 * 1024))is an expression that requires an assessment that you cannot do. Either replace it with a constant value 5242880, or do the calculation in __construct.

PHP 5.6, 2014 , " " , , .

Public is an ad that is used only in objects. This is not an object, delete the publication and this is normal.
