本文介绍了一个PHP脚本，用于获取当前日期、本周起始及结束日期、上一周的日期范围等，并通过函数计算两个日期之间的天数差。此外，还展示了如何确定当前月份所在的季度及其对应的日期范围。

<? php
echo date ( " Ymd " , strtotime ( " now " )) , " \n " ;
echo date ( " Ymd " , strtotime ( " -1 week Monday " )) , " \n " ;
echo date ( " Ymd " , strtotime ( " -1 week Sunday " )) , " \n " ;
echo date ( " Ymd " , strtotime ( " +0 week Monday " )) , " \n " ;
echo date ( " Ymd " , strtotime ( " +0 week Sunday " )) , " \n " ;

echo " *********第几个月: " ;
echo date ( ' n ' );
echo " *********本周周几: " ;
echo date ( " w " );
echo " *********本月天数: " ;
echo date ( " t " );
echo " ********* " ;

echo ' 上周: ' ;
echo date ( " Y-m-d H:i:s " , mktime ( 0 , 0 , 0 , date ( " m " ) , date ( " d " ) - date ( " w " ) + 1 - 7 , date ( " Y " ))) , " \n " ;
echo date ( " Y-m-d H:i:s " , mktime ( 23 , 59 , 59 , date ( " m " ) , date ( " d " ) - date ( " w " ) + 7 - 7 , date ( " Y " ))) , " \n " ;
echo ' 本周: ' ;
echo date ( " Y-m-d H:i:s " , mktime ( 0 , 0 , 0 , date ( " m " ) , date ( " d " ) - date ( " w " ) + 1 , date ( " Y " ))) , " \n " ;
echo date ( " Y-m-d H:i:s " , mktime ( 23 , 59 , 59 , date ( " m " ) , date ( " d " ) - date ( " w " ) + 7 , date ( " Y " ))) , " \n " ;

echo ' 上月: ' ;
echo date ( " Y-m-d H:i:s " , mktime ( 0 , 0 , 0 , date ( " m " ) - 1 , 1 , date ( " Y " ))) , " \n " ;
echo date ( " Y-m-d H:i:s " , mktime ( 23 , 59 , 59 , date ( " m " ) , 0 , date ( " Y " ))) , " \n " ;
echo ' 本月: ' ;
echo date ( " Y-m-d H:i:s " , mktime ( 0 , 0 , 0 , date ( " m " ) , 1 , date ( " Y " ))) , " \n " ;
echo date ( " Y-m-d H:i:s " , mktime ( 23 , 59 , 59 , date ( " m " ) , date ( " t " ) , date ( " Y " ))) , " \n " ;

$season = ceil (( date ( ' n ' )) / 3 ); // 当月是第几季度
echo ' 本季度: ' ;
echo date ( ' Y-m-d H:i:s ' , mktime ( 0 , 0 , 0 , $season * 3 - 3 + 1 , 1 , date ( ' Y ' ))) , " \n " ;
echo date ( ' Y-m-d H:i:s ' , mktime ( 23 , 59 , 59 , $season * 3 , date ( ' t ' , mktime ( 0 , 0 , 0 , $season * 3 , 1 , date ( " Y " ))) , date ( ' Y ' ))) , " \n " ;

$season = ceil (( date ( ' n ' )) / 3 ) - 1 ; // 上季度是第几季度
echo ' 上季度: ' ;
echo date ( ' Y-m-d H:i:s ' , mktime ( 0 , 0 , 0 , $season * 3 - 3 + 1 , 1 , date ( ' Y ' ))) , " \n " ;
echo date ( ' Y-m-d H:i:s ' , mktime ( 23 , 59 , 59 , $season * 3 , date ( ' t ' , mktime ( 0 , 0 , 0 , $season * 3 , 1 , date ( " Y " ))) , date ( ' Y ' ))) , " \n " ;
?>

php两个日期相减得天数
<? php
function count_days( $a , $b ){
$a_dt = getdate ( $a );
$b_dt = getdate ( $b );
$a_new = mktime ( 12 , 0 , 0 , $a_dt [ ' mon ' ] , $a_dt [ ' mday ' ] , $a_dt [ ' year ' ]);
$b_new = mktime ( 12 , 0 , 0 , $b_dt [ ' mon ' ] , $b_dt [ ' mday ' ] , $b_dt [ ' year ' ]);
return round ( abs ( $a_new - $b_new ) / 3600 / 24 );
}
 function count_days( $formdate , $todate ){
 return round ( abs ( strtotime ( $formdate ) - strtotime ( $todate )) / 3600 / 24 );
 }
