JAVASCRIPT code to get echo'ed values in HTML format

class MyJavaScriptInterface
        {
            @JavascriptInterface
            @SuppressWarnings("unused")
            public void processHTML(final String html)
            {


               String order_page = ""+Html.fromHtml(html);//process php output to html

               String CCAvenueOrder_id = order_page.split("\\_")[0];
               String CCAvenueTacking_id=order_page.split("\\_")[1];
               String CCAvenueOrderStatus=order_page.split("\\_")[2];


                // process the html as needed by the app
                String status = null;

                if(html.indexOf("Failure")!=-1){
                    status = "Transaction Declined!";
                }else if(html.indexOf("Success")!=-1){
                    status = "Transaction Successful!";

                Intent intent = new     Intent(getApplicationContext(),StatusActivity.class);

                startActivity(intent);

与问题的评论一样，您可以将输入存储在变量中。不需要使用输出缓冲区，至少在您的示例中不是这样。

<?php       
    $workingKey='XXXX';     //Working Key should be provided here.
    $encResponse=$_POST["encResp"];         //This is the response sent by the Server
    $rcvdString=decrypt($encResponse,$workingKey);      //Crypto Decryption used as per the specified working key.      
    $order_status="";
    $order_id=0;        
    $decryptValues=explode('&', $rcvdString);
    $dataSize=sizeof($decryptValues);
    $output = "<center>";    
    for ($i = 0; $i < $dataSize; $i++) {
        $information=explode('=',$decryptValues[$i]);
        if($i==0)   $order_id = $information[1];
        if($i==1)   $tracking_id = $information[1];
        if($i==3)   $order_status = $information[1];
    }
    $output .= $order_id."_";  
    $output .= $tracking_id."_";
    $output .= $order_status;
    echo $output; // response for ajax request as simple string
?>

检查运行代码内部情况的最佳方法是使用调试器，例如xdebug。了解如何安装它并与您选择的IDE一起使用，然后放置断点并使用监视来查看变量内部。 Here's how to do it with PhpStorm

如果您无法安装调试器，或者您绝对需要保留这些值，请了解日志的概念。有一个用于记录的PHP-FIG标准（PSR-3）和至少一个实现它的工具 - 例如Monolog。
