My implementation for type "double" | Patch about pb4php HOT 6 OPEN

Thank you dude ... do you have the same kind of things for : floats, uint32, 
uint64, fixed 32, fixed64, sfixed32, sfixed64 ? :D

use function unpack will return a array,so i use function array_shift bug it.
the same to the File "pb_double.php" i suggest.

File "pb_float.php":
-------------------------
<?php
/**
 * @author forthxu (http://forthxu.com)
 */
class PBFloat extends PBScalar
{
    var $wired_type = PBMessage::WIRED_64BIT;

    public function ParseFromArray()
    {
        $this->value = '';

        // just extract the string
        $pointer = $this->reader->get_pointer();
        $this->reader->add_pointer(4);
        $www_forthxu_com = unpack('f', $this->reader->get_message_from($pointer));
        $this->value = array_shift($www_forthxu_com);
    }

    /**
     * Serializes type
     */
    public function SerializeToString($rec=-1)
    {
        $string = '';
        if ($rec > -1)
        {
            $string .= $this->base128->set_value($rec << 3 |
$this->wired_type);
        }

        $string .= pack("f", (double)$this->value); 

        return $string;
    }
}
-------------------------

Don't forget to include this file in pb_message.php:
-------------------------
require_once(dirname(__FILE__). '/' . 'type/pb_float.php');
-------------------------

And specify this class as class to work with this type in pb_parser.php:
-------------------------
var $scalar_types = array(..., 'double', 'float' => 'PBFloat', 'int32' =>
'PBInt', 'int64' => 'PBInt',
-------------------------

Beware, if you want to use both pbDouble and pbFloat, the related pbFloat 
weird_type is WIRED_32BIT.
