how can count number of visits on page period of time in php , sql

right have field called number of visits every page. number not tell time of visits. not mind opening new column counting visits month. how can that?

why doing that? monthly report showing me website pages improved more other. ideas? codes?

everything welcomed

if it's quick tracking, include counter script each page. here's crude illustration in php:

<?php     $datafile = 'pick_a_filename.txt';     if(file_exists($datafile)) {         $count = file_get_contents($datafile);         $count++;         $fp = fopen($datafile, 'w');         fwrite($fp, $count);         fclose($fp);     } else {         $count = 1;         $fp = fopen($datafile, 'w');         fwrite($fp, $count);         fclose($fp);     } ?>

and check created file every month, or add script appends contents statistic file every month. if there's lots of traffic, include lock_ex , random delay before writing count not reset when 2 people write @ same time - has happened me on small site when used lock_ex! random delay fixed it.

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
