Declare Members at top of Class or Just Before Use?

Hi guys,

Not that it makes the slightest bit of difference to the execution of the script, but is it better practice to declare members (particularly variables) at the top of a class, or just before they are used?

Either:

Code:

<?php

class Controllername extends Controller {
    
    /**#@+
    * @access private
    * @var string
    **/
    protected $var1;
    protected $var2;
    protected $var3;
    protected $var4;
    /**#@-*/

    function someFunction12()
    {
    $this->var1 = $var1;
    $this->var2 = $var2;
    
    ...more code here...
    }

    function someFunction34()
    {
    $this->var1 = $var3;
    $this->var2 = $var4;
    
    ...more code here...
    }

?>

or:

Code:

<?php

class Controllername extends Controller {
    
    /**#@+
    * @access private
    * @var string
    **/
    protected $var1;
    protected $var2;
    /**#@-*/

    function someFunction12()
    {
    $this->var1 = $var1;
    $this->var2 = $var2;
    
    ...more code here...
    }

    /**#@+
    * @access private
    * @var string
    **/
    protected $var3;
    protected $var4;
    /**#@-*/

    function someFunction34()
    {
    $this->var1 = $var3;
    $this->var2 = $var4;
    
    ...more code here...
    }

?>

(obviously this is a minimal example!)

Cheers,
