preg_replace semicolon and ampersand to HTML entity on the same time

Question

Is it possible to replace semicolon and ampersand to her HTML entity on the same time?

$string = "one & two; three & four; end";
$result = preg_replace('/\;|\&/',";|&",$string);
echo $result;
// one ;|& two;|& three ;|& four;|& end

preg_replace with array dont solved it.

$string = "one & two; three & four; end";

$pattern = array("/\;/","/\&/");
$replace = array(";","&");

$result = preg_replace($pattern,$replace,$string);

echo $result;

// ne & two; three & four; end

Questions and answers with "preg_replace" dont solved it. "strtr" with an array solved it only. https://www.php.net/manual/de/function.strtr.php
