Are there any known bugs in PHP or Apache that could cause the omission of 3 characters at the end of a response from a SoapServer?

There are no known bugs in PHP or Apache that specifically cause the omission of 3 characters at the end of a response from a SoapServer. However, this issue could potentially be caused by incorrect handling of the response data within the SoapServer implementation or by encoding/decoding mismatches. To solve this issue, ensure that the response data is properly formatted and encoded before sending it back to the client.

// Example of ensuring proper response formatting in a SoapServer implementation
class MySoapServer extends SoapServer {
    public function handle() {
        ob_start();
        parent::handle();
        $response = ob_get_clean();
        
        // Ensure response ends with 3 characters
        if (substr($response, -3) !== 'end') {
            $response .= 'end';
        }
        
        echo $response;
    }
}

// Usage
$server = new MySoapServer(null, array('uri' => 'http://example.com/soap'));
$server->setClass('MySoapClass');
$server->handle();
