找出一个月中给定日期的周数

Posted 2021-02-25

This simple function allows you to find a weeks position in the month based on a given date. For instance I needed to alert the user their date was the "Second Week Of January" during a given month. I may never use it again but it came in very handy for this particular project.

<?php
 
function week_number( $date = 'today' ) 
{ 
    return ceil( date( 'j', strtotime( $date ) ) / 7 ); 
 
} 
 
?>
 
Usage Example:
 
<?php
 
$week_num = week_number();
 
$month = date("J", time());
 
echo "Today is the $week_num week of $month";
 
?>
