PHP Simple HTML DOM Parser returns null on multiple classes

Question

I'm trying to parse this HTML from remote url using Simple HTML DOM Parser:

<div class="_5pbx userContent _3ds9 _3576" data-ft="data-ft='{"tn":"K"}'">
<p>text to be parsed</p>
<p>the rest of text</p>
</div>

The PHP snipe I used is as the following:

include (getdomain . "/lib/simple_html_dom.php");

$html = new simple_html_dom();
$get = file_get_contents("http://localhost/get/d.json");
$html->load($get);
foreach ($html->find('div[class=_5pbx userContent _3ds9 _3576]') as $link) {
 if(isset($link)){
          echo $link->plaintext ;
    }
  }

But it didn't work, I'm aware of the <p> tag and I tried to add if statement for that but still didn't work, as the following:

include (getdomain . "/lib/simple_html_dom.php");

$html = new simple_html_dom();
$get = file_get_contents("http://localhost/get/d.html");
$html->load($get);
foreach ($html->find('div[class=_5pbx userContent _3ds9 _3576]') as $link) {
 if(isset($link)){
foreach($link->find('p') as $tag)
    {
          echo $tag->plaintext ;
    }
  }
}

But all didn't work :(

Any idea?

Are you getting any PHP errors or warnings either displayed or logged? Also, in your include, is the getdomain a defined symbol in your system? Or is it a function? — Shaun Bebbers

Yes getdomain to get the domain, I the code works when i try to get other elements like title echo $html->find('title',0)->plaintext;, but for the class with multiple classes it fails. — user9774304

Firstly, think about what you're naming and why. If getdomain is a method, think also about camelCase and I'm pretty sure that a method or function always requires () if said method/function requires no additional parameters - if it's a defined constant then I would use CAPSCASE, not because you want to shout at other developers, but to alert them that getdomain is a constant. Otherwise it looks like a typo, either a variable with a missing $ at the start, or a function/method with missing () - finally getdomain sounds like a getter so how would one set it? — Shaun Bebbers

I tried this. It is working..

<?php
include (getcwd() . "/simple_html_dom.php");
$html = new simple_html_dom();
$get = file_get_contents("http://localhost/zdemo/php%20selenium/d.json");
$html->load($get);
foreach ($html->find('div[class=_5pbx userContent _3ds9 _3576]') as $link) 
{
    if(isset($link))
    {
          echo $link->plaintext ;
    }
}
