我有一个记录集,它从SQL数据库中提取各种信息,包括日期。我想做的是计算从特定日期到今天的工作日数。我基本上知道自第一次约会以来已经过了多少个工作日。
我在工作日没有问题,这里有很多非常有用的帖子。我遇到的问题是我需要在数据库中填充的表中的每一行上重复。但由于每行的变量不同,在第一个结果之后页面是空白的,因为我假设脚本试图使用相同的命名变量再次运行。
有没有办法为这个总和包含php代码,以便它可以在下一行中使用相同的变量运行而不会影响前一行?
提前感谢您的帮助。
<?php

//In the first case the whole interval is within a week, in the second case the interval falls in two weeks.

}
}
//The no. of business days is: (number of weeks between the two dates) * (5 working days) + the remainder

$approval = date('Y-m-d',strtotime($row_rsworksorders1['intraartapproval']));
$w_days = getWorkingDays($approval,(date('Y-m-d'))) . ' Days';
echo $w_days;
?>

从数据库中提取的日期是$ row_rsworksorders1 [&#39; intraartapproval&#39;])
