答

You can use $_SERVER['HTTP_HOST']

For http://localhost/velocity/wordpress/?page_id=4 it will return http://localhost

答

Hope it will help you .

printf("MySQL host info: %s
", mysql_get_host_info());

You can also try .

<?php
echo gethostname(); // may output e.g,: sandie

// Or, an option that also works before PHP 5.3
echo php_uname('n'); // may output e.g,: sandie
?>
