Warning: DOMDocument::loadHTML(): htmlParseEntityRef: expecting ';' in Entity,
Catchable fatal error: Object of class DOMDocument could not be converted to string in test.php on line 10

Answer 1

To evaporate the warning, you can use libxml_use_internal_errors(true)
// create new DOMDocument
$document = new \DOMDocument('1.0', 'UTF-8');
// set error level
$internalErrors = libxml_use_internal_errors(true);
// load HTML
$document->loadHTML($html);
// Restore error level
libxml_use_internal_errors($internalErrors);

Answer 2

I would bet that if you looked at the source of http://www.somesite.com/ you would find special characters that haven't been converted to HTML. Maybe something like this:
link
Should be
link

Answer 3

$dom->#loadHTML($html);
This is incorrect, use this instead:
#$dom->loadHTML($html);

Answer 4

There are 2 errors: the second is because $dom is no string but an object and thus cannot be "echoed". The first error is a warning from loadHTML, caused by invalid syntax of the html document to load (probably an & (ampersand) used as parameter separator and not masked as entity with &).
You ignore and supress this error message (not the error, just the message!) by calling the function with the error control operator "#" (http://www.php.net/manual/en/language.operators.errorcontrol.php )
#$dom->loadHTML($html);

Answer 5

The reason for your fatal error is DOMDocument does not have a __toString() method and thus can not be echo'ed.
You're probably looking for
echo $dom->saveHTML();

Answer 6

Regardless of the echo (which would need to be replaced with print_r or var_dump), if an exception is thrown the object should stay empty:
DOMNodeList Object
(
)
Solution
Set recover to true, and strictErrorChecking to false
$content = file_get_contents($url);
$doc = new DOMDocument();
$doc->recover = true;
$doc->strictErrorChecking = false;
$doc->loadHTML($content);
Use php's entity-encoding on the markup's contents, which is a most common error source.

Answer 7

replace the simple
$dom->loadHTML($html);
with the more robust ...
libxml_use_internal_errors(true);
if (!$DOM->loadHTML($page))
{
$errors="";
foreach (libxml_get_errors() as $error) {
$errors.=$error->message."<br/>";
}
libxml_clear_errors();
print "libxml errors:<br>$errors";
return;
}

Answer 8

$html = file_get_contents("http://www.somesite.com/");
$dom = new DOMDocument();
$dom->loadHTML(htmlspecialchars($html));
echo $dom;
try this

Answer 9

I know this is an old question, but if you ever want ot fix the malformed '&' signs in your HTML. You can use code similar to this:
$page = file_get_contents('http://www.example.com');
$page = preg_replace('/\s+/', ' ', trim($page));
fixAmps($page, 0);
$dom->loadHTML($page);
function fixAmps(&$html, $offset) {
$positionAmp = strpos($html, '&', $offset);
$positionSemiColumn = strpos($html, ';', $positionAmp+1);
$string = substr($html, $positionAmp, $positionSemiColumn-$positionAmp+1);
if ($positionAmp !== false) { // If an '&' can be found.
if ($positionSemiColumn === false) { // If no ';' can be found.
$html = substr_replace($html, '&', $positionAmp, 1); // Replace straight away.
} else if (preg_match('/&(#[0-9]+|[A-Z|a-z|0-9]+);/', $string) === 0) { // If a standard escape cannot be found.
$html = substr_replace($html, '&', $positionAmp, 1); // This mean we need to escape the '&' sign.
fixAmps($html, $positionAmp+5); // Recursive call from the new position.
} else {
fixAmps($html, $positionAmp+1); // Recursive call from the new position.
}
}
}

Answer 10

Another possibile solution is
$sContent = htmlspecialchars($sHTML);
$oDom = new DOMDocument();
$oDom->loadHTML($sContent);
echo html_entity_decode($oDom->saveHTML());

Answer 11

Another possibile solution is,maybe your file is ASCII type file,just change the type of your files.

Answer 12

Even after this my code is working fine , so i just removed all warning messages with this statement at line 1 .
<?php error_reporting(E_ERROR); ?>
