我将在我的代码中查看php错误,这会导致$time和$date数组出现两个错误。Php 说消息:未定义的偏移量:1 和 2 表示 $time 和 $date。
所以在我完成 explode() 之后的键是未定义的吗?这究竟是怎么回事,为什么会这样?我该如何解决这个问题?数组显示的结果来自我在使用 print_r 时可以看到的数据库。
Array ( [0] => 05 [1] => 51 [2] => 00 )
Array ( [0] => 1984 [1] => 06 [2] => 23 )
我尝试了几件事,似乎都没有奏效。我不记得我以前有过这个问题...我几乎会开始想,也许这个问题可能与Codeigniter有关?

更新:忘记提及数组具有来自数据库的结果并添加了错误。
检查其var_dump()
,然后相应地使用它进行索引。
$time = explode(":", $this->chart_time);
var_dump($time);
$date = explode("-", $this->chart_date);
var_dump($date);
但这不是获取日期和时间的日期、月份或时间的正确方法。
推荐:
<?php
$date = '2015-01-22';
$time = '18:16:12';
$dt = new DateTime($date);
$tm = new DateTime($time);
$day = $dt->format('d');
$month = $dt->format('m');
$year = $dt->format('Y');
$hour = $tm->format('H');
$min = $tm->format('i');
$sec = $tm->format('s');
演示:

文档:
http://docs.php.net/class.datetime
$time = explode(":", $this->chart_time);
//it seems $time does not have value for 1,2 index
//$time[1] $time[2] does not exists
这就是你收到警告的原因。
与
$date = explode("-", $this->chart_date);
确保$time至少有 3 个尺寸。如果大小小于 3,它将产生相同的警告。
