Hvordan analyseres i PHP og lagres i databasen?

Du vil have $es->innertext og ikke $es .
Prøv denne kode:

$html =file_get_html('https://www.espncricinfo.com/rankings/content/current/page/211271.html');
$es = $html->find('td[class=left]',37);
$query = "UPDATE my_table SET Column1='".$es->innertext."' WHERE Column2=123;";
