simple html dom 404 error

Hey guys I'm Have this code:

<?php

include './simple_html_dom.php';

//this link exists
$teste = new simple_html_dom("http://www.btolinux.com.br/");
echo $teste->original_size."<br>";
if($teste->original_size !== 0){
    $teste->find("html");
}

//At this time I'm forcing get a 404 error link.
$teste = new simple_html_dom("http://www.btolinux.com.br/error/");
echo $teste->original_size."<br>";
if($teste->original_size !== 0){
    $teste->find("html");
}

//Now I'm get the correct link again. Why the error persists?
$teste = new simple_html_dom("http://www.btolinux.com.br/");
echo $teste->original_size."<br>";
if($teste->original_size !== 0){
    $teste->find("html");
}

?>

So, in my code, when I found a 404 error link, in the next objects created with the same class, the error persists. How can I solve this problem?

To try this code get the Simple_dom_php in http://sourceforge.net/projects/simplehtmldom/files/

Try this code:

<?php
require_once("./simple_html_dom.php");          # simplehtmldom.sourceforge.net

$url="http://www.btolinux.com.br/";
$url404="http://www.btolinux.com.br/error/";

$teste = @file_get_html($url);
if ($teste && $teste->original_size) {
    echo $teste->original_size."<br>\n";
    $html = $teste->find("html");
}

$teste = @file_get_html($url404);
if ($teste && $teste->original_size) {
    echo $teste->original_size."<br>\n";
    $html = $teste->find("html");
}

$teste = @file_get_html($url);
if ($teste && $teste->original_size) {
    echo $teste->original_size."<br>\n";
    $html = $teste->find("html");
}
?>

My output was:

Try the @ to avoid warnings, like this:

<?php
//CORRECT
$url = "http://www.btolinux.com.br/";
$html = @file_get_contents($url);
if ($html!='') {
    $teste = new simple_html_dom($url);
    echo 'SIZE: '.$teste->original_size."<br>";    
}


//ERROR
$url = "http://www.btolinux.com.br/error/";
$html = @file_get_contents($url);
if ($html!='') {
    $teste = new simple_html_dom($url);
    echo 'SIZE: '.$teste->original_size."<br>";    
}
?>

SUGGESTION:

$teste = new simple_html_dom();
$teste->load_file("http://www.btolinux.com.br/");
...

... OR ...

$teste = file_get_html("http://www.btolinux.com.br/");

Have you tried using file_get_contents() first? For example if you use the code:

<?php
print_r(file_get_contents("http://www.btolinux.com.br/error/"));
?>

You'll see that there's an error, then you can try-catch it.
