Question

我正在使用带有链接的WhatsApp api

https://github.com/WHAnonymous/Chat-API/wiki/WhatsAPI-Documentation

在本教程中，我使用以下代码来接收消息：

    $username = $get_list['userid'];
    $password = $get_list['password'];
    $nickname = ''; 
    $debug = "false";

    $w = new WhatsProt($username, $nickname, $debug);
    try {
        $w->connect();
        $w->loginWithPassword($password);
        $w->sendMessage($username , '');
        $s = $w->pollMessage();
    } catch (Exception $e) {
        echo "Sorry ". $e->getMessage();
    }

我收到的信息如下：

tx  <stream:features>
tx    <readreceipts></readreceipts>
tx    <groups_v2></groups_v2>
tx    <privacy></privacy>
tx    <presence></presence>

tx  <auth mechanism="WAUTH-2" user="9195666669">����9195666669��/oNz|$%L�A#u)�1449637609</auth>

我没有在代码中编写任何print_r()，只是它正在打印代码。我不想打印此代码，而是希望将其存储到变量中。如何将其存储到变量中？

Answer 1

如果您可以控制调用print_r的代码，那么您可以将输出直接发送到变量：$var_info = print_r($var,true); - 请参阅https://stackoverflow.com/a/5762520/3012550

但是，由于函数定义is part of the library（第1788行），您似乎无法控制输出。因此，您可以使用此处所述的ob_start：https://stackoverflow.com/a/4798178/3012550

ob_start();
functionThatCallsPrintR();
$output = ob_get_clean();
// $output contains everything outputed between ob_start() and ob_get_clean()
