SCA::getService — Obtain a proxy for a service
本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。
Examine the target and initialize and return a proxy of the appropriate sort. If the target is for a local PHP component the returned proxy will be an SCA_LocalProxy. If the target is for a WSDL file, the returned proxy will be a SCA_SoapProxy.
An absolute or relative path to the target service or service description (e.g. a URL to a json-rpc service description, a PHP component, a WSDL file, and so on.). A relative path, if specified, is resolved relative to the location of the script issuing the getService() call, and not against the include_path or current working directory.
The binding (i.e. protocol) to use to communicate with the service (e.g binding.jsonrpc for a json-rpc service). Note, some service types can be deduced from the target parameter (e.g. if the target parameter ends in .wsdl then SCA will assume binding.soap). Any binding which can be specified in an annotation can be specified here. For example 'binding.soap' is equivalent to the '@binding.soap' annotation.
Any additional configuration properties for the binding (e.g. array('location' => 'http://example.org')). Any binding configuration which can be specified in an annotation can be specified here. For example, 'location' is equivalent to the '@location' annotation to configure the location of a target soap service.
The SCA_LocalProxy or SCA_SoapProxy.
Example #1 An SCA::getService() example
This example shows how to get a proxy to an email soap service described by EmailService.wsdl and located at http://example.org.
<?php
include 'SCA/SCA.php';
$service = SCA::getService('EmailService.wsdl', 'binding.soap', array('location' => 'http://example.org'));
$service->send(...);
?>
