Question

嗨朋友们，我已经学会了学习角js 我的问题是当我登录时，我的ajax reuest从lv_inbox_angular.php转到lv_inbox_angular.html。在php文件中有3个表leave history，leave approval和overtime history 所以我需要对这3 array($lvhistory , $apprleave ,$othistory )进行编码，我需要在lv_inbox_angular.html中显示它（当我同时登录时）

我的问题是，当我尝试使用超过1 print_r(json_encode($lvhistory))和print_r(json_encode($othistory))时，我的加班历史为空（因为我没有应用加班假），但它给出了[]同控制台中的error undefined [ 当我在网络标签中看到我会得到这个

[{"st_date":"2017-11-08","end_date":"2017-11-09","co_date":"0000-00-00","co_date2":null,"co_type":null,"co_desc":"NA","lv_type":"EL","status":"submitted","rpt_mgr":"aaa","lv_trans_id":"271"},{"st_date":"2017-11-20","end_date":"2017-11-20","co_date":"0000-00-00","co_date2":null,"co_type":null,"co_desc":"NA","lv_type":"EL","status":"submitted","rpt_mgr":"aaa","lv_trans_id":"272"}][]

我的代码是lv_inbox_angular.html

请帮助我解决这个问题

打印多个JSON对象时，它将不再是有效的响应。

您应该将所有PHP响应合并，并将print_r作为单个JSON对象合并到文件末尾，然后让AngularJS将它们拆分。

PHP：

// Top of your file
// Create a global variable
$arr = [];

// In your first function
// Add data to global array
$arr['first']  = $lvhistory;

// In your second function
// Use same logic as above
$arr['second'] = $othistory;

// This can be repeated for every function

// End of file
// Convert your array and print object
// Notice the second param: true
print_r(json_encode($arr, true));

角：

$http({
    // Your request
}).success(function(data) {

    // Now you can split it in your Angular app
    var lvhistory = data.data.first;
    var othistory = data.data.second;
});

如何将单个php文件中的1个以上json_encoded数组传递给angular js
