str_get_html is not loading a valid html string

Question

I receive an html string using curl: ``` curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $html_string = curl_exec($ch); ``` When I `echo` it I see a perfectly good html as I require for my parsing needs. But, When trying to send this string to `HTML DOM PARSER` method `str_get_html($html_string)`, It would not upload it (returns false from the method invocation). I tried saving it to file and opening with `file_get_html` on the file, but the same thing occurs. What can be the cause of this? As I said, the html looks perfectly fine when I echo it. Thanks a lot. The code itself: ``` $html = file_get_html("http://www.bgu.co.il/tremp.aspx"); $v = $html->find('input[id=__VIEWSTATE]'); $viewState = $v[0]->attr['value']; $e = $html->find('input=[id=__EVENTVALIDATION]'); $event = $e[0]->attr['value']; $html->clear(); unset($html); $body = " A_STRING_THAT_CONTAINS_SOME_DATA " $ch = curl_init("http://www.bgu.co.il/tremp.aspx"); curl_setopt($ch, CURLOPT_POSTFIELDS, $body); curl_setopt($ch, CURLO…

You curl link seems have many element(large file).

And I am parsing a string(file) as large as your link and encounter this problem.

After I saw the source code, I found the problem. It works for me !

I found that simple_html_dom.php have limit the size you read.

```
// get html dom from string
  function str_get_html($str, $lowercase=true, $forceTagsClosed=true, $target_charset = DEFAULT_TARGET_CHARSET, $stripRN=true, $defaultBRText=DEFAULT_B     R_TEXT, $defaultSpanText=DEFAULT_SPAN_TEXT)
  {
           $dom = new simple_html_dom(null, $lowercase, $forceTagsClosed, $target_charset, $stripRN, $defaultBRText, $defaultSpanText);
           if (empty($str) || strlen($str) > MAX_FILE_SIZE)
           {
                   $dom->clear();
                   return false;
           }
           $dom->load($str, $lowercase, $stripRN);
           return $dom;
  }
```

you must to change the default size below (It's on the top of the simple_html_dom.php) maybe change to 100000000 ? it's up to you.

```
define('MAX_FILE_SIZE', 6000000); 
```
