Get Google crawl date of a web site

Google crawl date in PHP

Google crawl date using PHP source code. Google bot crawls every web site after a specific period. You can check that date using Google's cache command in Google search engine. Here it is the example of Google cache.

http://64.233.183.104/search?q=cache%3Afree-computer-tips.info&sourceid=navclient-ff&ie=UTF-8&rlz=1B3GGGL_enPK238__238

I created PHP function which gets Google bot crawl date and returns in a form of string.
You can use these codes in your PHP applications.
Code are under the marks due to setting of page

function google_crawl_date($url){
  $output = file_get_contents('http://64.233.183.104/search?q=cache:'.
   urlencode($url).'&sourceid=navclient-ff&ie=UTF-8&rlz=1B3GGGL_enPK238__238');
  $match_expression = '/appeared on (.*). The <a href/Us';
  preg_match($match_expression,$output,$matches);
  if ($matches[1]=="") return "No Date found";
  else return $matches[1];
}

Usage of function above

<?php
  echo google_craw_date("http://free-computer-tips.info");
?>
