How to change product quantity with Ebay API

Question

I'm trying to do one simple thing. I want to change the quantity of an existing fixed priced item on ebay using PHP. Is this possible? I've asked this before and got responses telling me to read this or that. I'm not able to find any actual code examples though. I'd love to see someone post one. For example, ebay item number 123456789 has a qty of 50. I want to run some PHP code to change it to qty of 20. I want to enter the item number, the new quantity, and any ebay verification data needed into the code and run it. That's all I need.

Try this it works for me

$feed = <<< EOD
<?xml version="1.0" encoding="utf-8"?>
<ReviseItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">
<RequesterCredentials>
<eBayAuthToken>$eBay->auth_token</eBayAuthToken>
</RequesterCredentials>
<Item ComplexType="ItemType">
<ItemID>$itemid</ItemID>
<Quantity> int </Quantity>
</Item>
<MessageID>1</MessageID>
<WarningLevel>High</WarningLevel>
<Version>$eBay->api_version</Version>
</ReviseItemRequest>​
EOD;

$feed = trim($feed);
        $site_id = 3;//3 For UK
        $headers = array
            (
            'X-EBAY-API-COMPATIBILITY-LEVEL: ' . $this->api_version,
            'X-EBAY-API-DEV-NAME: ' . $this->dev_id,
            'X-EBAY-API-APP-NAME: ' . $this->app_id,
            'X-EBAY-API-CERT-NAME: ' . $this->cert_id,
            'X-EBAY-API-CALL-NAME: ' . $call_name,
            'X-EBAY-API-SITEID: ' . $site_id,
        );

        // Send request to eBay and load response in $response
        $connection = curl_init();
        curl_setopt($connection, CURLOPT_URL, $this->api_endpoint);
        curl_setopt($connection, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($connection, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($connection, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($connection, CURLOPT_POST, 1);
        curl_setopt($connection, CURLOPT_POSTFIELDS, $feed);
        curl_setopt($connection, CURLOPT_RETURNTRANSFER, 1);
        $response = curl_exec($connection);
        curl_close($connection);
