' &lm=1′; /* Domain name included in today's URL */ $utf _pattern = "/Find the relevant result number (. *)/"; $kz _pattern = "/(. *)/"; /* String to match the snapshot date */ $times = "/d{4}-d{1,2}-d{1,2}/"; /* Regular expressions that match the snapshot date, such as: 2011-8-4*/ $s 0 = @file_get_contents ($all); /* Place the Site:www.ninthday.net Web page into the $s0 string */ $s 1 = @file_get_contents ($today); Preg_match ($utf _pattern, $s 0, $all _num); /* Match "find related results * *" * * Preg_match ($utf _pattern, $s 1, $today _num); Preg_match ($kz _pattern, $s 0, $temp); Preg_match ($times, $temp [0], $screenshot); if ($all _num[1] = = "") $all _num[1] = 0; if ($today _num[1] = = "") $today _num[1] = 0; if ($screenshot [0] = = "") $screenshot [0] = "no snapshot"; ?> Test Date Baidu included Baidu today included Baidu Snapshot Date Baidu included: "target=" _blank "> Baidu today included: "target=" _blank "> Baidu Snapshot Date: ">

The above method is not strictly considered, if the server does not support the File_get_contents function we can not operate, so also use curl operation, this is more convenient to imitate the user Oh.
