LoadHTML 和 SaveHTML 无意循环

如何解决LoadHTML 和 SaveHTML 无意循环

我创建了一个函数来计算当前页面上的所有超链接，并将超链接更改为 https://www.google.com 。但是，我的页面上只有 1 个超链接，代码不断循环 29 次，我找不到原因。

function linkreplacer() {
$currenturl = file_get_contents((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"); //this is a wordpress function,i am positive that this works
$doc = new DOMDocument(); 
$doc->loadHTML($currenturl);
$elements = $doc->getElementsByTagName("a");
echo "The linkreplacer has found ".count($elements)." hyperlinks on this page </br>";
foreach($elements as $el) {
    $el->setAttribute('href',"https://www.google.com");
}
printf( '%s',$doc->saveHTML() );
}
