Domdocument Load not loading - php

Question

I am trying to load xml file through url(i.e. rss).
But when I Use
$doc = new DOMDocument();
$doc->load($url);
if($doc->load($url,LIBXML_NOWARNING)===false)
{
echo "Hello";
//echo #$doc->load($url,LIBXML_NOWARNING);
//exit;
$error = $doc->load($url);
print_r($error);exit;
}
It only prints Hello..
No warning displayed for line 2.
Please provide me solution that which error occurs as I am getting nothing.

Answer 1

Remove exit; from the code after echo "Hello"; that is the reason

Answer 2

That is because the rendered content is not visible. Try pressing Ctrl+U on your browser.
Also, instead of print_r try with var_dump
$error = $doc->load($url);
var_dump($error);
EDIT :
So it seems like your $doc->load failed in the first place. You need to change your if statement to
if($doc->load($url,LIBXML_NOWARNING)===true) // Replaced false with true.
or simply
if($doc->load($url,LIBXML_NOWARNING))
Your XML load failed that's why it went inside the if statement. Check whether the URL is spelled right or check if the URL really exists.

Try using libxml_use_internal_errors() to capture XML parsing errors:
<?php
$doc = new DOMDocument();
$doc->recover = true;
libxml_use_internal_errors(true);
$url = 'http://page2rss.com/rss/91a83628a27c43b6ab4f0b3959f69f5a';
$doc->load($url);
$errors = libxml_get_errors();
foreach ($errors as $error) {
printf("Error %d at line %d, column %d:\n\t%s\n",
$error->code, $error->line, $error->column, $error->message);
}
libxml_use_internal_errors(false);
// Error 9 at line 82, column 155:
// Input is not proper UTF-8, indicate encoding !
// Bytes: 0xAE 0x20 0x28 0x52
