simple question apache+php: if use simplexml-load-file make http request or load file filesystem in case have:

  • option a: simplexml_load_file('test.xml');
  • option b: simplexml_load_file('http://my.website.com/test.xml');

moreover in second option, php perform dns resolution of my.website.com or there bypass mechanism?

option load straight disk, option b perform http request, including dns lookup. there no bypass dns lookup, other modifying hosts file or putting in ip directly.
