' ~ '. $zce 1; To obtain a medium-time week $JZC = 0; The current month is 6 weeks or 5 weeks $jzc 0 = ""; $JZC 6 = ""; for ($i = $stimestamp; $i <= $etimestamp; $i +=86400) {if (date (' W ', $i) = = 0) {$jzc 0++;} if (Date (' W ', $i) = = 6) {$jzc 6++;}} if ($jzc 0==5 && $jzc 6==5) {$jzc = 5;} else{$jzc =4;} date_default_timezone_set (' PRC '); $t = Strtotime (' +1 Monday '. $msdate); $n = 1; for ($n =1; $n < $jzc; $n + +) {$b = Strtotime ("+ $n week-1 Week", $t); $dsdate =date ("y-m-d", Strtotime ("-1 day", $b)) $ded Ate=date ("y-m-d", Strtotime ("5 Day", $b)); $jzcz = $n +1; $ret [$jzcz]= ". $jzcz." Week ". $dsdate. ' ~ '. $dedate; }//For the last week $zcsy =date (' W ', $etimestamp);//Last week is weeks to six 0~6 $zcs 1=date (' y-m-d ', StRtotime ("-$zcsy Day", $etimestamp)); $zce 1= $medate; $jzcz = $jzc +1; $ret [$jzcz]= ". $jzcz." Week ". $zcs 1. ' ~ '. $zce 1; return $ret;} $ret =getmonthweeks (' 2012-12-01 '); for ($i =0; $i <=count ($ret); $i + +) {echo @ $ret [$i]. " <br/> ";}? >
