DOMDocument::loadHTML
(PHP 5)
DOMDocument::loadHTML — Load HTML from a string
Description
public bool DOMDocument::loadHTML ( string $source [, int $options = 0 ] )
The function parses the HTML contained in the string source. Unlike loading XML, HTML does not have to be well-formed to load. This function may also be called statically to load and create a DOMDocument object. The static invocation may be used when no DOMDocument properties need to be set prior to loading.
Parameters
source
The HTML string.
options
Since PHP 5.4.0 and Libxml 2.6.0, you may also use the options parameter to specify additional Libxml parameters.
Return Values
Returns TRUE on success or FALSE on failure. If called statically, returns a DOMDocument or FALSE on failure.
Errors/Exceptions
If an empty string is passed as the source, a warning will be generated. This warning is not generated by libxml and cannot be handled using libxml's error handling functions.
This method may be called statically, but will issue an E_STRICT error.
While malformed HTML should load successfully, this function may generate E_WARNING errors when it encounters bad markup. libxml's error handling functions may be used to handle these errors.
Examples
Example #1 Creating a Document
$doc = new DOMDocument();
$doc->loadHTML("Test
");
echo $doc->saveHTML();
?>
Changelog
Version Description
5.4.0 Added options parameter.

Curl file upload with multipart/form-data
have a problem with the file upload with curl. I want to upload a file of my server on a video hosting site. The script needs the Content-type: multipart/form-data and Content-type: video/mp4, but I dont know how I can do it. After the upload the file have the content type application/octet-stream.
Here is the script
class curl
{
function __construct($use = 1)
{
$this->ch = curl_init();
if($use = 1)
{
curl_setopt ($this->ch, CURLOPT_POST, 1);
curl_setopt ($this->ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt ($this->ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($this->ch, CURLOPT_RETURNTRANSFER, 1);
}
else
{
return 'There is the possibility, that this script wont work';
}
}
function first_connect($loginform,$logindata)
{
curl_setopt($this->ch, CURLOPT_URL, $loginform);
curl_setopt($this->ch, CURLOPT_POSTFIELDS, $logindata);
}
function store()
{
$this->content = curl_exec ($this->ch);
}
function execute($page)
{
curl_setopt($this->ch, CURLOPT_URL, $page);
$this->content = curl_exec ($this->ch);
}
function close()
{
curl_close ($this->ch);
}
function __toString()
{
return $this->content;
}
function upload($file)
{
curl_setopt($this->ch, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data"));
curl_setopt($this->ch, CURLOPT_URL, 'http://uploadsite.com/index.php?act=files&do=upload');
$postdata = array("file[]" => "@/".realpath($file));
echo $postdata;
curl_setopt($this->ch, CURLOPT_POSTFIELDS, $postdata);
curl_exec ($this->ch);
}
}
$getit = new curl();
$getit->first_connect('http://uploadsite.com/index.php?act=login&login=true','login=true&file_session=&email=xxx%40yahoo.de&password=xxx&upload=Login');
$getit->store();
$getit->execute('http://uploadsite.com/index.php?act=user&do=home');
$getit->upload('Sample.mp4');
And the package from livehttpheaders

Replace this line:
$postdata = array("file[]" => "@/".realpath($file));
with:
$postdata = array("file[]" => "@/".realpath($file).";type=video/mp4");
and it should work
I've used curl for connecting with a web service and upload a file using a similar idea of this post, but it didn't work. The reasons where different to the previous answer, so I will describe my solution; maybe my experience is useful to others.
I had two problems. The first one is that my web service didn't like absolute path in the filename. If $file in the OP code has a path, then using:
$postdata = array('file[]' => "@/".realpath($file));
becomes:
Content-Disposition: form-data; name="file[]"; filename="/tmp/iy56ham"
and that path generated a BAD REQUEST. So I had to use chdir, basename and dirname in order to avoid using paths in the $postdata.
On the other hand, curl sent an extra header, not shown in the OP:
Expect: 100-continue
My web service didn't like it (neither twitter WS) and it answered with a:
417 Expectation Failed
To avoid curl sending that offending header you can use:
curl_setopt( $curlHandler, CURLOPT_HTTPHEADER, array('Expect:') );
so you set an empty Expect header and curl will not overwritten with 100-continue.
Hope this help someone...
