So having managed to crack getting nusoap to poll the chemspider server for information

  • 0

So having managed to crack getting nusoap to poll the chemspider server for information however I get a response that will display using print_r but when using print will simply display Array.

My question is this really, how do I take the given response and turn it into a php array

The code for the nusoap client

<?php
require_once('../lib/nusoap.php');
$client = new nusoap_client('http://www.chemspider.com/Search.asmx?WSDL', 'wsdl');
$err = $client->getError();
if ($err) {
    echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
}
$query = 'methanol';
$token = 'token';
$result = $client->call(SimpleSearch, array('query' => $query, 'token' => $token), array('return' => 'xsd:string'), "http://www.chemspider.com/SimpleSearch") ;
// Check for a fault
if ($client->fault) {
    echo '<h2>Fault</h2><pre>';
    print_r($result);
    echo '</pre>';
} else {
    // Check for errors
    $err = $client->getError();
    if ($err) {
    // Display the error
    echo '<h2>Error</h2><pre>' . $err . '</pre>';
} else {
    // Display the result
    echo '<h2>Result</h2><pre>';
    print_r($result);
    echo '</pre>';
}
}



echo '<h2>Request</h2><pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';
echo '<h2>Response</h2><pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre>';
echo '<h2>Debug</h2><pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre>';
?>

This gives the following output (minus the debug information):

Result

Array
(
    [SimpleSearchResult] => Array
        (
           [int] => 864
        )

 )

    In the script you use, the response has already been parsed to a PHP array called $result. You’ve already got the array printed in the output as well.

    Your issue is, as far as I can see, the fact that print() and echo() do not work well on arrays. They simply output the type (Array) instead of the contents.

    You can call the output of $result with

    print $result['simpleSearchResult']['int'] // Will display 864

    You can read more on PHP’s array handling in the PHP Manual.
