PHP converts date format to xx days ago format _php Tips

This example describes the way PHP converts date formats to XX days. Share to everyone for your reference. Specifically as follows:

This code can format the time 3 days ago, 5 seconds ago, 2 years ago.

Convert a date into a string "tells how long"//That date is ... eg:2 days ago, 3 minutes ago.
 Function ago ($d) {$c = getdate ();
 $p = Array (' Year ', ' mon ', ' mday ', ' hours ', ' minutes ', ' seconds ');
 $display = Array (' Year ', ' Month ', ' Day ', ' hour ', ' minute ', ' second ');
 $factor = Array (0, 12, 30, 24, 60, 60);
 $d = Datetoarr ($d);
  for ($w = 0; $w < 6 $w + +) {if ($w > 0) {$c [$p [$w]] = = $c [$p [$w-1]] * $factor [$w];
 $d [$p [$w]] + + = $d [$p [$w-1]] * $factor [$w]; } if ($c [$p [$w]]-$d [$p [$w]] > 1) {return ($c [$p [$w]]-$d [$p [$w]]). ' '. $display [$w]. '
 S ago ';
} return '; 
}//You can replace this if need is. This converts I dates returned from a MySQL date string//into an array object similar to that returned by GETDATE ()
. function Datetoarr ($d) {Preg_match ("/[0-9]{4}] (\\-) ([0-9]{2}) (\\-) ([0-9]{2}) ([0-9]{2}) (\:) ([0-9]{2}) (\:) ([0-9
 ]{2})/", $d, $matches); Return array (' seconds ' => $matches [ten], ' minutes ' => $matches [8], ' Hours ' => $Matches[6], ' mday ' => $matches [5], ' mon ' => $matches [3], ' year ' => $matches [1]; }
