calling webservice using php

I am new to PHP and wanted to write a snippet of code which would call a Webservice. I have the java equivalent code for it that works correctly.

HttpClient client=new HttpClient();
GetMethod method=new GetMethod(URL);
method.addRequestHeader("test1","test1");
String statusCode=client.executeMethod();
if (statusCode != HttpStatus.SC_OK) {
       System.err.println("Method failed: " + method.getStatusLine());
}
// Read the response body.
byte[] responseBody = method.getR开发者_开发技巧esponseBody();
// Deal with the response.
// Use caution: ensure correct character encoding and is not binary data
System.out.println(new String(responseBody));

There are a bunch of different ways to do it.

If you're just trying to send a simple GET request, file_get_contents will work just fine. (Note: you can also do POST requests with file_get_contents in conjunction with stream_context_create, but there are other ways I find nicer)

Example:

$response = file_get_contents("http://www.example.com/webservice?foo=bar&baz=1");

Another method is to use cURL. This may not be available on all systems (but should be on most). Here's an example of a POST request using curl:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/webservice');
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array('foo'=>'bar','baz'=>1)));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
$result = curl_exec($ch);

Alternatively, another way is to use the PEAR package HTTP_Request2. This will work on all systems and can be a nice way to do it. For more information and examples, see the manual page.

Your should use some webservice dedicated methods, it would be easier. For example if your webservice is a SOAP one : http://php.net/manual/fr/book.soap.php, or an XML-RPC : http://www.php.net/manual/en/book.xmlrpc.php

Look at httprequest-send in php, that should get you started in terms of building the right request.
