Question

使用下面的代码我有一个问题，我得到第1和第2行就好了，但第3行和下一行只会出现此错误：

注意：未定义的偏移量：C：\ xampp \ htdocs \ h_php \ addTimes.php中的1 第19行。

<?php
$timearry="";
$timearry=array("1:10","1:40","1:20","0:50");
$i=0;
$day1hours="";
foreach($timearry as $times){
    if($i==0){
        echo $day1hours= $times;
        echo "<br>";
    }else{
        $day2hours = $times;
        $day1=array();
        $day1 = explode(":", $day1hours);
        $day2 = explode(":", $day2hours);
        $totalmins = 0;
        $totalmins += $day1[0] * 60;
        $totalmins += $day1[1];
        $totalmins += $day2[0] * 60;
        $totalmins += $day2[1];
        $hoursTotal = $totalmins / 60;
        $hours=0;
        $hours = explode(".", $hoursTotal);
        $hours= $hours[0];
        $minutes = $totalmins % 60;
        echo $day1hours = "$hours".'Hours '."$minutes".' Mints';
        echo "<br>";
    }
    $i++;
}
?>

根据你的逻辑，

这是错误

SublimeLinter: golint activated: /Users/gianmarco/Documents/Dev/Go/bin/golint 
Emmet: No need to update PyV8
SublimeLinter: chdir not set or invalid, using /Users/gianmarco/Documents/Dev/Go/src/github.com/gianmarco/hello

此行应为

echo $day1hours = "$hours" . 'Hours ' . "$minutes" . ' Mints';

输出：

echo $day1hours = $hours . ':'.$minutes;

这不是错误，只是一个通知，告诉您在代码的第19行，您使用的是不存在的偏移量。

假设您发布的代码已完成，则表示此行无法正常运行：

$totalmins += $day2[1];

因为$day2数组似乎没有2个元素。

您是否检查$timearry中的所有元素是否格式正确为“H：m”？

注意：未定义的偏移量：第19行的C：\ xampp \ htdocs \ h_php \ addTimes.php中的1
