DOMDocument::loadHTML — Load HTML from a string
   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.
  
sourceThe HTML string.
options
       Since Libxml 2.6.0, you may also use the
       options parameter to specify additional Libxml parameters.
      
   Returns true on success or false on failure. If called statically, returns a
   DOMDocument or false on failure.
  
   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.
  
Prior to PHP 8.0.0 this method
could be called statically, but would issue an E_DEPRECATED error.
As of PHP 8.0.0 calling this method statically throws an Error exception
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.
