echo $innerHTML_contents

嘗試使用此功能

function DOMinnerHTML($element) 
{ 
    $innerHTML = ""; 
    $children = $element->childNodes; 
    foreach ($children as $child) 
    { 
     $tmp_dom = new DOMDocument(); 
     $tmp_dom->appendChild($tmp_dom->importNode($child, true)); 
     $innerHTML.=trim($tmp_dom->saveHTML()); 
    } 
    return $innerHTML; 
} 

像

$dom = new DOMDocument; 
$dom->loadHTML($html_string); 
$divs = $dom->getElementsByTagName('div'); 
$innerHTML_contents = DOMinnerHTML($divs->item(0)); 
echo $innerHTML_contents 

輸出

<strong><span style="font-size:200%;">My Name is Rashid Farooq</span></strong>
