Question

여기에 많은 "관련"답변을 모두 남기고, Google에 오기 전에 많이 사용하십시오.

PHP 코드를 사용하여 XML을 처음 접했습니다. 이후에 (

<?php 

error_reporting(E_ALL); ini_set('display_errors', 1); 

$xml=simplexml_load_file("test.xml") or die("Error: Cannot create object"); 

foreach($xml->questions as $multipleChoiceQuestion) { 
    echo $multipleChoiceQuestion->multipleChoiceQuestion['id']; 
    echo "<br>"; 
} 
?> 

내 목표는 모든 ID 질문을 얻을 수 있습니다 :

그리고 PHP 코드 : 여기

내가 찾고 있어요 XML 파일 (test.xml의)입니다 데이터베이스에 넣으십시오.)

foreach는 XML 문서의 첫 번째 자식 (구조에 대한 제어권이 없음) 만 살펴보고 중지되는 것으로 보입니다. 실행하면 첫 번째 질문 ID 만받습니다.

{3BFC44A3-137B-496B-900D-E6908253C106} 
{2CEDBF79-0864-4E1A-954A-F7CA17989314} 
{71221928-8909-44BC-94B4-C0C011E297F7} 
{C6CDB118-B4E0-4856-A7AB-69A35CEBBB44} 

내가 얻을 :

{3BFC44A3-137B-496B-900D-E6908253C106} 

내가 무엇을 놓치고

나는 다음과 같은 결과를 기대하고있어?

Answer 1

question 노드가 하나뿐이므로 루프에서 하나의 반복 만 얻습니다.

실제로 첫 번째 노드를 파고 들기 때문에 첫 번째 값을 얻게됩니다.

echo $multipleChoiceQuestion->multipleChoiceQuestion['id']; 

기본적으로 두 개의 노드가 루프 깊숙한 곳으로 이동 한 다음 루프의 깊이가 깊습니다.

<?php 

error_reporting(E_ALL); ini_set('display_errors', 1); 

$xml=simplexml_load_file(__DIR__."/test.xml") or die("Error: Cannot create object"); 

foreach($xml->questions->multipleChoiceQuestion as $multipleChoiceQuestion) { 
    echo $multipleChoiceQuestion['id']; 
    echo "<br>"; 
} 

이 출력 :

{3BFC44A3-137B-496B-900D-E6908253C106
} {2CEDBF79-0864-4E1A-954a 내지-F7CA17989314} {
71221928-8909-44BC-94B4-C0C011E297F7 이 없기 때문에}
{C6CDB118-B4E0-4856-A7AB-69A35CEBBB44}
