$currentTime = time();
$cyear = floor(date("Y",$currentTime));
$cMonth = floor(date("m",$currentTime));

for($i=0;$i<6;$i++){
$nMonth = $cMonth-$i;
$cyear = $nMonth == 0 ? ($cyear-1) : $cyear;
$nMonth = $nMonth <= 0 ? 12+$nMonth : $nMonth;
$date = $cyear."-".$nMonth."-1";
$firstday = date('Y-m-01', strtotime($date));
$lastday = date('Y-m-t', strtotime($date));

echo $cyear."年".$nMonth."月";
echo "第一天:".$firstday;
echo "最后一天:".$lastday,"";
}
