SCA::getService — Obtain a proxy for a service
此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。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.
target
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.
binding
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.
config
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(...);
?>
