How to send and recieve XML data to and from an API service in PHP without cURL

Question

I'm working a project to request data from api service by sending XML data. The programming language used is PHP. I have done so much research on the internet and nothing turned up except for using cURL. Is there any other way using PHP to achieve this.

<?php
$xml_data = '<mainservice>
               <customer>
                  <appln_id>myid</appln_id>
                  <password>mypasss</password>
                  <cust_id>1234</cust_id>
               </customer>
             </mainservice>';

This is the data that needs to be send. The id and password is for authenticating the API service and cust_id for retrieving data of that particular customer.

The Result data is also in XML format.

NOTE The service accepts only POST data.

Post data using file_get_contents() funtion

 $xml_data = '<mainservice>
               <customer>
                  <appln_id>myid</appln_id>
                  <password>mypasss</password>
                  <cust_id>1234</cust_id>
               </customer>
             </mainservice>';


$postdata = http_build_query(
    array(
        'xml_data' => $xml_data,
        'var2' => 'abc'
    )
);

$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);

$context  = stream_context_create($opts);

$result = file_get_contents('http://example.net/submit.php', false, $context);

Get data using file_get_contents() function

<?php 
$json_url = "http://api.example.com/test.php?type=menu";
$json = file_get_contents($json_url);
$data = json_decode($json);

echo "<pre>";
print_r($data);
echo "</pre>";

how does it work with XML? I need to send

$xml_data = '<mainservice>                <customer>                   <appln_id>myid</appln_id>                   <password>mypasss</password>                   <cust_id>1234</cust_id>                </customer>              </mainservice>';

Replace "$postdata" variable to your one, let me update answer

Mayank Dudakiya Over a year ago

You can try above answer, you just need to change the URL here file_get_contents('http://example.net/submit.php', false, $context); to where you want to send the data

Nope. That didn't work. var_dump($result) is returning bool(false)

Please see the code here https://www.tehplayground.com/e0934u36dPj5mu4d . If the call is successful, it will return user authentication error.

You must see

https://davidwalsh.name/web-service-php-mysql-xml-json

Hope you will find your solution.

You can also use this

$xml = file_get_contents('post_xml.xml');
$url = 'http://stg.sa.com/post.asmx/';
$post_data = array(
    "xml" => $xml,
);

$stream_options = array(
    'http' => array(
       'method'  => 'POST',
       'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
       'content' => http_build_query($post_data),
    ),
);

$context  = stream_context_create($stream_options);
$response = file_get_contents($url, null, $context);

thanks for the link. but it only shows reading and printing the XML data received from the web-service. How do I send data in XML format to the web-service using POST.

<head>
    <meta charset="UTF-8">
    <title>test handle response</title>
    <script>
        var xmlhttp = new XMLHttpRequest();
        xmlhttp.open("POST","URL to Request");
        var xmlDoc;
        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
            xmlDoc = xmlhttp.responseXML;
            console.log(xmlDoc);
            }
        };
        xmlhttp.setRequestHeader('Content-Type', 'text/xml');
        var xml = "<?xml version='1.0'?><query><author>John Steinbeck</author></query>";
        xmlhttp.send(xml);
    </script>
