The function you would want to call is "setBlobProperties" and just pass the new content type of the blob in "options" parameter. You can look at the source code here: https://github.com/Azure/azure-sdk-for-php/blob/master/WindowsAzure/Blob/BlobRestProxy.php.

Hope this helps.

Gaurav, thanks for reply

I have the next code, and nothing...

        $blobName = "010fd745c58c315fd44f6ff6abd730c7.jpg" ;

        $blobOption = new CreateBlobOptions(); 
        $blobOption->setBlobContentType("image/jpeg") ;

         $ok = $blobRestProxy->setBlobProperties("company", $blobName, $blobOption) ;
         echo "Error : " . $ok ."<br />";

Do you have some example to show me?

The apache Log is :

[06-Apr-2014 05:17:56 Europe/Berlin] PHP Fatal error:  Call to undefined method WindowsAzure\Blob\Models\CreateBlobOptions::getBlobContentLength() in /Applications/MAMP/htdocs/Kaltin/vendor/microsoft/windowsazure/WindowsAzure/Blob/BlobRestProxy.php on line 1894

Try this code:

<?php
require_once 'WindowsAzure.php';
use WindowsAzure\Common\ServicesBuilder;
use WindowsAzure\Common\ServiceException;
use WindowsAzure\Blob\Models\SetBlobPropertiesOptions;
try {
  $containerName = "{containername}";
  $blobName = "{blobname}";
  $contentType = "{contenttype e.g image/jpg}";
  $connectionString = 'DefaultEndpointsProtocol=http;AccountName={accountname};AccountKey={accountkey}';
  $queueRestProxy = ServicesBuilder::getInstance()->createQueueService($connectionString);
  $blobRestProxy = ServicesBuilder::getInstance()->createBlobService($connectionString); 
  $blobOption = new SetBlobPropertiesOptions();
  $blobOption->setBlobContentType($contentType);
  $ok = $blobRestProxy->setBlobProperties($containerName, $blobName, $blobOption);
  echo "Error : " . $ok;
  }
catch(ServiceException $e){
$code = $e->getCode();
    $error_message = $e->getMessage();
    echo $code.": ".$error_message."<br />";
}  
?>
Hope this helps.
