[82] => Array ( [day] => 22/10/2019 [totalprice] => 235.00 )
[83] => Array ( [day] => 23/10/2019 [totalprice] => 235.00 )
[84] => Array ( [day] => 24/10/2019 [totalprice] => 235.00 )
[85] => Array ( [day] => 25/10/2019 [totalprice] => 235.00 )
[86] => Array ( [day] => 26/10/2019 [totalprice] => 235.00 )
[87] => Array ( [day] => 27/10/2019 [totalprice] => 235.00 )
[88] => Array ( [day] => 28/10/2019 [totalprice] => 235.00 )

[90] => Array ( [day] => 30/10/2019 [totalprice] => 235.00 )
[91] => Array ( [day] => 31/10/2019 [totalprice] => 235.00 )
)
使用以下代码:
foreach($blankarray as $rate){
if ($rate['totalprice'] == '0'){
} else {
$firstrate = $rate['totalprice'];
if ($firstrate != $previousrate) {
$firstdate = $rate['day'];
echo '<br>'.$firstdate;
echo '</br><font color="green"> <b>'.$firstrate .'</b></font>';
$previousrate = $firstrate;
}
我明白了:
01/08/2019
585.00
01/09/2019
410.00
01/10/2019
235.00
当总价格发生变化时,如何添加上一个日期以便我可以拥有:
01/08/2019
31/08/2019
585.00
01/09/2019
30/09/2019
410.00
01/10/2019
31/10/2019
235.00
【问题讨论】:
-
输入数据中410.00和235.00在哪里?
-
你想要的输出的逻辑是什么?我完全看不出它与您的示例输入有什么关系
-
我删除了数组的 500 行,所以你必须发挥你的想象力:(
-
问题是在价格变化时做一些事情。但价格永远不变。
-
我们不需要 500 行,但我们需要一些反映实际问题的内容。
