如何在JSON响应中使用if条件

Question

下面是我以JSON格式读取xml和编码输出的代码

<?php
error_reporting(E_ERROR | E_PARSE);
require_once("xml2json.php");

$testXmlFile = 'http://newsonair.nic.in/NSD.asp';

$xmlStringContents = file_get_contents($testXmlFile); 
$jsonContents = "";
$jsonContents = xml2json::transformXmlStringToJson($xmlStringContents);

$tempResponseArrays = array();
$obj =json_decode($jsonContents);

foreach($obj->rss->channel->item as $item) {
 $tempResponse = array();
    if ($item->title == Dogri){
     $tempResponse['title'] = $item->title;
     $tempResponse['date'] = $item->pubDate;
     $tempResponse['link'] = $item->link;
    }
     $tempResponseArrays[] = $tempResponse;    

} 
echo json_encode(array('item' => $tempResponseArrays));

?>

上面没有if条件的代码给出了JSON以下的响应

{
"item":[

我想从“”标题“获取标题为”Dogri“的项目：”Dogri：1915-1930“，”。 “Dogri”之后的值如“：1915-1930”将永远改变。如何从标题字符串中获取“Dogri”？

Answer 1

也许是这样的？

if (strpos($item->title, "Dogri")===0) {
    ...
}
