how to use the namespace classes in php

Question

I have a class with namespace which require many other classes further . main class is

<?php
/**
 * Deals with PDF document level aspects.
 */
namespace Aspose\Cloud\Pdf;

use Aspose\Cloud\Common\AsposeApp;
use Aspose\Cloud\Common\Product;
use Aspose\Cloud\Common\Utils;
use Aspose\Cloud\Event\SplitPageEvent;
use Aspose\Cloud\Exception\AsposeCloudException as Exception;
use Aspose\Cloud\Storage\Folder;

class Document
{

    public $fileName = '';

    public function __construct($fileName='')
    {
        $this->fileName = $fileName;
    }

    /**
     * Gets the page count of the specified PDF document.
     *
     * @return integer
     */
     public function getFormFields()
    {
        //build URI
        $strURI = Product::$baseProductUri . '/pdf/' . $this->getFileName() . '/fields';

        //sign URI
        $signedURI = Utils::sign($strURI);

        //get response stream
        $responseStream = Utils::ProcessCommand($signedURI, 'GET', '');

        $json = json_decode($responseStream);

        return $json->Fields->List;
    }
}

I am using this like this in index.php

<?
ini_set('display_errors', '1');
use Aspose\Cloud\Pdf;

$document=new Document;
echo $document->GetFormFields();

//or like this 
echo Document::GetFormFields();

//also tried this 
echo pdf::GetFormFields();

?>

Error

Fatal error: Class 'Document' not found in /var/www/pdfparser/asposetry/index.php on line 5

Document class path is Aspose/Cloud/Pdf/Document.php

namespace Aspose\Cloud\Pdf;

class Document {
    ...

To use this class, you'll have to write

use Aspose\Cloud\Pdf\Document

You can also access it without a use statement, but then you'll have to write the full name every time:

$document=new Aspose\Cloud\Pdf\Document;

// Or if you're in a namespace, you'll have to do this:

$document=new \Aspose\Cloud\Pdf\Document;

Fatal error: Class 'Aspose\Cloud\Pdf\Document' not found in /var/www/pdfparser/asposetry/index.php on line 5 is the error – Manoj Dhiman May 16 '15 at 09:21
@ris You'll either have to `include` each class file, or define an autoloader to do it for you. Take a look here: http://php.net/manual/en/language.oop5.autoload.php – Schlaus May 16 '15 at 09:22

You are trying to use the Document class that's inside the Aspose\Cloud\Pdf namespace, but you are actually using a Document class without a namespace. You have to use one of the following ways:

//Option one:
use Aspose\Cloud\Pdf\Document;
Document::getFormFields();

//Option two:
Aspose\Cloud\Pdf\Document::getFormFields();

Also note that you can't use Document::getFormFields() as a static function, because it is not static. You should make it static (by putting static between public and function) or use it on an object.

You probably forgot to actually include the file with the Document class somewhere in your application. Use autoload or inlcude the file manually: `include('Aspose/Cloud/Pdf/Document.php');` – redelschaap May 16 '15 at 09:24
now error move to next class. i have to include classess in every class??? this is the error now Fatal error: Class 'Aspose\Cloud\Pdf\Product' not found in /var/www/pdfparser/asposetry/Aspose/Cloud/Pdf/Document.php on line 365 – Manoj Dhiman May 16 '15 at 09:32
maybe you should consider some autoloader for loading your classes automatically? Standard PHp http://php.net/manual/de/language.oop5.autoload.php – AdamM May 16 '15 at 09:34
Yes, you'll either have to include each class seperately (though only once in your application) or use an autoloader as @AdamM suggests. An autoloader checks whether you've already loaded (included) a class when you're using one. If not, it will include it for you. – redelschaap May 16 '15 at 09:36
where can i define __autoload function ?? i have defiend in index.php still same errors – Manoj Dhiman May 16 '15 at 09:47
Using an autoloader is not that simple when your classes are located in different folders. Take a look at http://stackoverflow.com/a/9628060/1997303 and try to adjust that to your needs. – redelschaap May 16 '15 at 09:55
