SOAP Client

In our client we’re going to call webmethod “getWeather”, with wanted city for input parameter (string). And if we get a valid response we’ll
output received data (degree, forecast). The code:

<?php    
    /**************************************************************
    *  Description:
    *  Creates a simple SOAP Client (client.php).
    **************************************************************/
    // use form data
    if ((string)$_GET['action'] == 'get_data') {
        // includes nusoap classes
        require('inc/nusoap.php');
        // set parameters and create client
        $l_aParam   = array((string)$_POST['city']);
        $l_oClient  = new soapclient('http://somewhere.org/soap/server.php');
        // call a webmethod (getWeather)
        $l_stResult = $l_oClient->call('getWeather', $l_aParam);
        // check for errors
        if (!$l_oClient->getError()) {
          // print results
          print '<h1>Current data for: '    . $l_aParam[0] 
              . ':</h1><ul><li>DEGREES: '   . $l_stResult['degrees'] 
              . '&deg;C</li><li>FORECAST: ' . $l_stResult['forecast'] 
              . '</li></ul>'; 
        }
        // print error description
        else {
          echo '<h1>Error: ' . $l_oClient->getError() . '</h1>';
        }
    }
    // output search form
    print '
        <form name="input" action="'.$_SERVER['PHP_SELF'].'?action=get_data"  method="POST">
        Your city: <input type="text" name="city">
        <input type="submit" value="Search">
        </form>
    ';
?>
