allow_url_fopen的simplexml补丁用于simplehtmldom

Question

My hosting company has disabled allow_url_fopen & allow_url_include. They recommend that I use cURL instead, then I saw this patch on simplexml

$calendar = simplexml_load_file($source); with
if (ini_get('allow_url_fopen')) {
$calendar =       simplexml_load_file($source); 
}   
else {    
$ch = curl_init($source);    
curl_setopt  ($ch, CURLOPT_HEADER, false); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    
$xml_raw = curl_exec($ch);    
$calendar = simplexml_load_string($xml_raw);  }

and it works on my hosting so I was wondering if I could use it on simplehtmldom here is the code I am using

<?php
include('simple_html_dom.php');
include ('phpQuery.php');   
// Create DOM from URL
$html = file_get_html('http://www.urlhere.com/');
   ?>

Can i use this? If yes what changes should I make, thank you for your help

Edited above code

<?php
include('simple_html_dom.php'); 
include ('phpQuery.php'); 

if (ini_get('allow_url_fopen')) {       
$html = file_get_html('http://www.weather.bm/'); }
else{       $ch = curl_init('http://www.weather.bm/');           
curl_setopt  ($ch, CURLOPT_HEADER, false);        
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);           
$src = curl_exec($ch);           
$html = str_get_html($src, false); 
var_dump($html);  }   

?>

You'd need to edit the simple_html_dom source. Its easier to just create your own function that does what the original does. The original (which you can't use because of allow_url_fopen) is:

function file_get_html() {
    $dom = new simple_html_dom;
    $args = func_get_args();
    @$dom->load(call_user_func_array('file_get_contents', $args), true);
    if (($error=error_get_last())!==null)
    throw new Exception($error['message']);
    return $dom;
}

You can just do this:

if (ini_get('allow_url_fopen')) {
      $html = file_get_html('http://www.urlhere.com/');
}else{
      $ch = curl_init('http://www.urlhere.com/');    
      curl_setopt  ($ch, CURLOPT_HEADER, false); 
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    
      $src = curl_exec($ch);    
      $html = str_get_html($src, false);
}

No need to modify the source, and effectively does the same thing.
