Note Submitter: Laurent Houdijk ---- This function calculaties the days between two data (Ymd) By example, if $datum1 = 20071215 and $datum2 = 20081215, the output will be 366 ;-) <?php function calculate_day_between($datum1,$datum2) { if( is_numeric($datum1) && is_numeric($datum2) && strlen($datum1) == 8 && strlen($datum2) == 8 ) { $dat = ($datum1 < $datum2)? $datum1 : $datum2; $datv = ($datum1 < $datum2)? $datum2 : $datum1; $i = 0; while( $dat < $datv) { $i++; switch(substr($dat,6,2)) { case '28': $dat += (substr($dat,4,2) == 02 && substr($dat,0,4)%4 > 0 )? 73 : 1; break; case '29': $dat += (substr($dat,4,2) == 02 && substr($dat,0,4)%4 == 0 )? 72 : 1; break; case '30': $dat += (in_array( substr($dat,4,2), array(04,06,09,11)))? 71 : 1; break; case '31': $dat += (substr($dat,4,2) == 12 )? 8870 : 70; break; default: $dat++; break; } } return $i-1; } else { return false; } } ?>
