Question

我想要的是我在表中有5条记录，日期 - ＆gt; 2017-03-12,2017-03-23,2017-03-25,2017-03-28,2017-03-29和他们有价格 - ＆gt; 10,20,30,40,50。

我想要生成一个报告，其中显示的日期介于12到29之间.12,13,14,15等等到它们的价格，如果这个日期没有可用的价格，它应该采用之前的价格记录。对于前者，对于日期13,14,15，它应该取10的价格，而对于日期24，它应该取20的价格。

关于它的任何想法？

Answer 1

你走了。

$dates['2017-03-12'] = 10;
$dates['2017-03-23'] = 20;
$dates['2017-03-25'] = 30;
$dates['2017-03-28'] = 40;
$dates['2017-03-29'] = 50;

$start = min(array_keys($dates));

$end = max(array_keys($dates));


$list = array();
while($start <= $end){

    $value = $dates[$start];

    if(!is_null($value))
        $last_value = $value;   

    $list[] = array("date" => $start,"value" => $last_value);

    $start = date('Y-m-d',strtotime($start."+1day"));

}

print_r($list);

这将打印
