如何，如果在JSON状态REPONSE

Question

使用下面是我的代码来读取JSON格式的XML和编码输出

<?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)); 

?> 

上面的代码没有如果条件给出以下JSON响应

"item":[

我'想要从“”标题“中获取带有标题”Dogri“的唯一项目：”Dogri：1915-1930“，”。 “Dogri”之后的值像“：1915-1930”将会一直改变。如何从标题字符串中获得“Dogri”？

Answer 1

也许这样吗？

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