How PHP get the content from web service?

This page contains dynamic content, loaded by JavaScript. You can see it in Google Chrome for example by access view-source:http://server1-xeon.asuscomm.com/currency/?amount=1.20,from=MYR,to=SGD.

If you look closer to the source code of the page (file http://server1-xeon.asuscomm.com/currency/JQuery/app_converter.js) you'll see, that it uses this code to get exchange data under the hood:

$.ajax({type: "POST",        url: "WebService.asmx/YaHOO_CurrencyEx",  // important: it's a relative URL!        data: "{amount:" + amount + ",fromCurrency:'" + from + "',toCurrency:'" + to + "'}",        contentType: "application/json; charset=utf-8",        dataType: "json",        beforeSend: function () {},        success: function (data) {            $('#results').html(' [ ' + amount + from + ' , ' + data.d.toFixed(2) + to + ' ] ');        });

So, actually you can make such request in PHP to avoid access dynamic content on the http://server1-xeon.asuscomm.com/currency/?amount=1.20,from=MYR,to=SGD page.

UPD:I've added a more complete explanation.

By the time the page on http://server1-xeon.asuscomm.com/currency/?amount=1.20,from=MYR,to=SGD is loaded, a JavaScript code on this page (it means that it's executed on the client side, in a browser, not on your server) parses URL parameters and makes AJAX POST request to the URL http://server1-xeon.asuscomm.com/currency/WebService.asmx/YaHOO_CurrencyEx. It passes a JSON payload {amount:1.20,fromCurrency:'MYR',toCurrency:'SGD'} and gets a response like this {"d":0.390360}. So, you can just make a direct POST request to the http://server1-xeon.asuscomm.com/currency/WebService.asmx/YaHOO_CurrencyEx via curl, passing an amount, fromCurrency and toCurrency in JSON body and then decode received JSON response using json_decode($content);.

How data should look? Add this to your code from "UPDATED" and run:

$array["MYR"] = 1.2;$array["SGD"] = doubleval($obj->d)// Print simple array (print source for example)echo "<pre>";print_r($array);echo "</pre>";// Print true JSON-arrayprint_r(json_encode($array));

In web browser you will see:

Array(    [MYR] => 1.2    [SGD] => 0.39036){"MYR":1.2,"SGD":0.39036}

Can't understand your problem at this moment.

If you want print only returned value (digits), do it: echo $obj->d;
