사용하는 기능의 메신저

public function getXML($url){ 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
    curl_setopt($ch, CURLOPT_URL,$url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
    $response = curl_exec($ch); 

    return simplexml_load_string($response); 
} 

이다가 나는 것이 있습니다 있어야 할 곳에 없는? 다른 결과가 반환되는 이유는 무엇입니까?

Answer 1

함수 simplexml_load_string은 해석 된 XML 만 SimpleXMLElement 객체로 반환합니다. ... 어떻게 분석하고 요소를 반복하는

SimpleXMLElement 오브젝트는 iterable 및 accessible 같습니다

public function getXML($url){ 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
    curl_setopt($ch, CURLOPT_URL,$url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
    $response = curl_exec($ch); 

    // return $xml if you still want to parse the data elsewhere 
    $xml = simplexml_load_string($response); 

    // return this if you just want the raw XML string 
    return $xml->asXML(); 
} 

업데이트 : 대신 SimpleXMLElement::asXML을보십시오.

foreach ($xml->GetMatchingProductResult->Product as $product) { 
    // do something for each <Product>, such as output the ASIN... 
    echo $product->Identifiers->MarketplaceASIN->ASIN; 
} 

당신은 더 많은 예제에 대한 Basic SimpleXML usage에 PHP 문서를 참조 할 수 있습니다 : 이것은 당신이 요소를 반복하는 foreach를 사용할 수 있다는 것을 의미합니다. 어떤 시점에서 네임 스페이스를 처리해야합니다. 여기에 몇 가지 추가 리소스는 다음과 같습니다 제가 예를 들어, 결과 데이터를 추출을 통해 볼 수있을 것입니다 방법, 이것에 대해
