本文实例讲述了php根据年月获取当月天数及日期数组的方法。分享给大家供大家参考,具体如下:
function get_day( $date )
{
$tem = explode('-' , $date); //切割日期 得到年份和月份
$year = $tem['0'];
$month = $tem['1'];
if( in_array($month , array( 1 , 3 , 5 , 7 , 8 , 01 , 03 , 05 , 07 , 08 , 10 , 12)))
{
// $text = $year.'年的'.$month.'月有31天';
$text = '31';
}
elseif( $month == 2 )
{
if ( $year%400 == 0 || ($year%4 == 0 && $year%100 !== 0) ) //判断是否是闰年
{
// $text = $year.'年的'.$month.'月有29天';
$text = '29';
}
else{
// $text = $year.'年的'.$month.'月有28天';
$text = '28';
}
}
else{
// $text = $year.'年的'.$month.'月有30天';
$text = '30';
}
return $text;
}
echo get_day('2016-8-1');
运行结果为:31
改造,返回日期数组:
function get_day( $date ,$rtype = '1')
{
$tem = explode('-' , $date); //切割日期 得到年份和月份
$year = $tem['0'];
$month = $tem['1'];
if( in_array($month , array( 1 , 3 , 5 , 7 , 8 , 01 , 03 , 05 , 07 , 08 , 10 , 12)))
{
// $text = $year.'年的'.$month.'月有31天';
$text = '31';
}
elseif( $month == 2 )
{
if ( $year%400 == 0 || ($year%4 == 0 && $year%100 !== 0) ) //判断是否是闰年
{
// $text = $year.'年的'.$month.'月有29天';
$text = '29';
}
else{
// $text = $year.'年的'.$month.'月有28天';
$text = '28';
}
}
else{
// $text = $year.'年的'.$month.'月有30天';
$text = '30';
}
if ($rtype == '2') {
for ($i = 1; $i <= $text ; $i ++ ) {
$r[] = $year."-".$month."-".$i;
}
} else {
$r = $text;
}
return $r;
}
var_dump(get_day('2016-8-1','2'));
运行结果如下:array(31) {
[0]=>
string(8) "2016-8-1"
[1]=>
string(8) "2016-8-2"
[2]=>
string(8) "2016-8-3"
[3]=>
string(8) "2016-8-4"
[4]=>
string(8) "2016-8-5"
[5]=>
string(8) "2016-8-6"

[22]=>
string(9) "2016-8-23"
[23]=>
string(9) "2016-8-24"
[24]=>
