Bug description: PHP 5.3+ support for namespace wildcards (use statement)
Description:
------------
When using namespaces you always have to put the exact 'use \ClassName'
statement into the code. This list of dependencies can become quite large
in some classes. To relieve programmers from having to manually put use
statements to the top (or elsewhere) a namespace wildcard should be added
to the language.
Much like in Java, where in stead of writing
import java.awt.Image;
import javax.swing.JTextField;
import javax.swing.JComboBox;
import javax.swing.JSpinner;
import javax.swing.JCheckBox;
import javax.swing.JRadioButton;
import javax.swing.JMenuItem;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
one could write
import java.awt.*;
import javax.swing.*;
This saves a lot of time while writing the code. An IDE (plugin) might
replace the wildcards with the actually used classes.
Wrting
use \*;
seems natural to me. Don't know how much this RFE is possible
language-wise. It would however make lots of sense for PHP 5.3.
I'm not sure if this is the right place to ask for a language enhancement
of this caliber.
Reproduce code:
---------------
<?php
namespace whatever; //in dir whatever
//use \*; <- why not???
//PHP standard classes
use \Exception;
//ZF classes
use \Zend_Version;
class ZfTools
{
public static function checkVersion($strRequiredVersion = '1.5.1')
{
switch ( Zend_Version::compareVersion($strRequiredVersion) )
{
case -1: //required is older
return true;
case 0: //equal
case 1: //newer
return false;
default: //should never be executed
throw new Exception('Error comparing Zend
Framework version!');
}
}
}
?>
Expected result:
----------------
use \*;
would compile so that Zend_Version and Exception can be used without
leading backslashes.
Actual result:
--------------
use \*;
Generates a parse error "Parse error: parse error, expecting `T_STRING' in
C:\dev\apache\htdocs\whatever\ZfTools.php on line 5"
