在视图文件中显示

想知道何时在视图文件中声明该错误Undefined offset: 1

但是当我将数组从[1-5]更改为[0]时，它可以正常工作，但是根本没有任何数据吗？如果您知道是什么原因造成的，则在下面发帖确实会有所帮助。谢谢！：）

Answer 1

首先，将您的$array_issues声明更改为其中一个

$array_issues = array();

或

$array_issues = [];

然后，我不知道您在这方面要完成什么：

$results = json_decode($server_output2);

$j=0;
// to get each object from an array of object
foreach((array)$results as $result){ 
    if($j==3)
    $array_issues[$i] = $result;

    $j++;
}

但是，我认为这不能正确初始化您的$array_issues[0]索引，它甚至可能没有输入……我至少会在if和foreach之外初始化索引，例如：

$j=0;
// to get each object from an array of object
$array_issues[$i] = ""; // MAKING SURE THIS IS AT LEAST DEFINED.
foreach((array)$results as $result){ 
    if($j==3)
    $array_issues[$i] = $result;

    $j++;
}

此外，我认为您可以使用$ key => $ value语法而不是该$ j计数器来完成您要执行的操作...

$array_issues[$i] = ""; // MAKING SURE THIS IS AT LEAST DEFINED.
foreach((array)$results as $key => $result){ 
    if($key==3)
    $array_issues[$i] = $result;
}

Deepcrawl获取数据：未定义偏移1
