Several methods for obtaining php time

Function getWeekName ($ data, $ format = 'week ') { $ Week = date ("D", $ data ); Switch ($ week) { Case "Mon ": $ Current = $ format. "1 "; Break; Case "Tue ": $ Current = $ format.

'hour ago '; } Else { If ($ dur <259200) {// within 3 days Return floor ($ dur/86400). 'Days ago '; } Else { Return $ the_time; } } } } } } ?> 5. calculate the time difference based on the difference Function getTime ($ val ){ If ($ val> 0 ){ $ NTime ['nday'] = (int) ($ val/(3600*24 )); $ NTime ['nhour'] = (int) ($ val % (3600*24)/3600 ); $ NTime ['nmin'] = (int) ($ val % (3600*24) % 3600/60 ); $ NTime ['nss'] = (int) ($ val % (3600*24) % 3600% 60 ); } Return $ nTime; } Function getStrTime ($ val ){ $ ATime = getTime ($ val ); $ Dtoc = array ('nday' => 'day', 'nhour' => 'hour ', 'nmin' => 'min ', 'nss' => 'second '); If ($ aTime ){ Foreach ($ aTime as $ k => $ v ){ If ($ v ){ $ CTime. = $ v. $ dtoc [$ k]; } } } Else { $ CTime = 'stopped '; } Return $ cTime; } ?>
