我已经在PHP中开发了一段时间了，我从来没有遇到需要从PHP核心类扩展的情况。
我遇到一个问题，我有一个Soap Webservices Provider，他的SOAP服务写得非常好，所以PHP-CLIENT类给了我很多验证错误。无论如何，他们的SOAP＆＃34;工作＆＃34;，不是应该但它确实如此。
我想要做的是从此类扩展并修改验证，例如，不控制targetNamespace具有该位置的不同名称。我知道我不应该这样做，但我不想从头开始编写SOAP类。
当我试图从这个类（SoapClient）扩展时，我意识到方法中根本没有代码，我找不到原因。我想也许是因为这些方法可以在＆＃34; C＆＃34;环境，或者它们已被编译以使其更快。如果不是这种情况，我很乐意看到这个类的代码并根据我的需要进行修改。
欢迎任何建议，提示或解释。我附上了SoapClient代码。
class SoapClient {
/**
* (PHP 5 >= 5.0.1)<br/>
* SoapClient constructor
* @link http://php.net/manual/en/soapclient.soapclient.php
* @param mixed $wsdl <p>
* URI of the WSDL file or <b>NULL</b> if working in
* non-WSDL mode.
* </p>
* <p>
* During development, WSDL caching may be disabled by the
* use of the soap.wsdl_cache_ttl <i>php.ini</i> setting
* otherwise changes made to the WSDL file will have no effect until
* soap.wsdl_cache_ttl is expired.
* </p>
* @param array $options [optional] <p>
* An array of options. If working in WSDL mode, this parameter is optional.
* If working in non-WSDL mode, the location and
* uri options must be set, where location
* is the URL of the SOAP server to send the request to, and uri
* is the target namespace of the SOAP service.
* </p>
* <p>
* The style and use options only work in
* non-WSDL mode. In WSDL mode, they come from the WSDL file.
* </p>
* <p>
* The soap_version option should be one of either
* <b>SOAP_1_1</b> or <b>SOAP_1_2</b> to
* select SOAP 1.1 or 1.2, respectively. If omitted, 1.1 is used.
* </p>
* <p>
* For HTTP authentication, the login and
* password options can be used to supply credentials.
* For making an HTTP connection through
* a proxy server, the options proxy_host,
* proxy_port, proxy_login
* and proxy_password are also available.
* For HTTPS client certificate authentication use
* local_cert and passphrase options. An
* authentication may be supplied in the authentication
* option. The authentication method may be either
* <b>SOAP_AUTHENTICATION_BASIC</b> (default) or
* <b>SOAP_AUTHENTICATION_DIGEST</b>.
* </p>
* <p>
* The compression option allows to use compression
* of HTTP SOAP requests and responses.
* </p>
* <p>
* The encoding option defines internal character
* encoding. This option does not change the encoding of SOAP requests (it is
* always utf-8), but converts strings into it.
* </p>
* <p>
* The trace option enables tracing of request so faults
* can be backtraced. This defaults to <b>FALSE</b>
* </p>
* <p>
* The classmap option can be used to map some WSDL
* types to PHP classes. This option must be an array with WSDL types
* as keys and names of PHP classes as values.
* </p>
* <p>
* Setting the boolean trace option enables use of the
* methods
* SoapClient->__getLastRequest,
* SoapClient->__getLastRequestHeaders,
* SoapClient->__getLastResponse and
* SoapClient->__getLastResponseHeaders.
* </p>
* <p>
* The exceptions option is a boolean value defining whether
* soap errors throw exceptions of type
* SoapFault.
* </p>
* <p>
* The connection_timeout option defines a timeout in seconds
* for the connection to the SOAP service. This option does not define a timeout
* for services with slow responses. To limit the time to wait for calls to finish the
* default_socket_timeout setting
* is available.
* </p>
* <p>
* The typemap option is an array of type mappings.
* Type mapping is an array with keys type_name,
* type_ns (namespace URI), from_xml
* (callback accepting one string parameter) and to_xml
* (callback accepting one object parameter).
* </p>
* <p>
* The cache_wsdl option is one of
* <b>WSDL_CACHE_NONE</b>,
* <b>WSDL_CACHE_DISK</b>,
* <b>WSDL_CACHE_MEMORY</b> or
* <b>WSDL_CACHE_BOTH</b>.
* </p>
* <p>
* The user_agent option specifies string to use in
* User-Agent header.
* </p>
* <p>
* The stream_context option is a resource
* for context.
* </p>
* <p>
* The features option is a bitmask of
* <b>SOAP_SINGLE_ELEMENT_ARRAYS</b>,
* <b>SOAP_USE_XSI_ARRAY_TYPE</b>,
* <b>SOAP_WAIT_ONE_WAY_CALLS</b>.
* </p>
* <p>
* The keep_alive option is a boolean value defining whether
* to send the Connection: Keep-Alive header or
* Connection: close.
* </p>
* <p>
* The ssl_method option is one of
* <b>SOAP_SSL_METHOD_TLS</b>,
* <b>SOAP_SSL_METHOD_SSLv2</b>,
* <b>SOAP_SSL_METHOD_SSLv3</b> or
* <b>SOAP_SSL_METHOD_SSLv23</b>.
* </p>

就像对待任何PHP类一样：
class mySoapClient extends SoapClient {
//override parent function
public function nativeFunction() {
//...some logic ...
}
}
关键是你需要知道它是否会像你想要的那样容易。有时更容易使用第三方库，您可以访问代码并查看如何更改代码。

最后解决方案根本不是很好。
在将SOAP类连接到有很多问题的服务的情况下，我所做的是下载WSDL结构并根据我的需要进行修改。
我不喜欢这个解决方案，因为如果API供应商改变了什么，我就不会知道它。
在下面的代码中，您可以看到为固定XML调用SOAP调用并询问服务。
$urlXML = "FIXEDXML.xml";
$cliente = new SoapClient($urlXML, array(
"trace" => true,
'soap_version' => SOAP_1_1,
'cache_wsdl' => WSDL_CACHE_NONE
));
var_dump($cliente);
echo "<h1> FUNCIONES DISPONIBLES </h1>";
echo '<pre>';
$functiones = $cliente->__getFunctions();
var_dump($functiones);
echo '</pre>';
} catch (Exception $exc) {
var_dump($exc);
echo $exc->getTraceAsString();
}
我希望这对某人有用。我很长一段时间都试图让它发挥作用。
