나는 PHP/컬 파일이

<?php 
echo "Conversion Stats<br />"; 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_HEADER, 0); 
curl_setopt($ch, CURLOPT_VERBOSE, 0); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)"); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_URL,'http://login.leadkitchen.com/affiliates/api/4/reports.asmx/Conversions'); 
$post_array = array(
     'affiliate_id' => '123', 
    'api_key' => 'abc', 
    'start_date' => '10/8/2012', 
    'end_date' => '10/11/2012', 
    'offer_id' => '123', 
    'start_at_row' => '1', 
    'row_limit' => '0', 
    'sub_affiliate' => 'email' 
); 

//url-ify the data 
foreach($post_array as $key=>$value) 
{ 
    $post_array_string .= $key.'='.$value.'&'; 
} 
$post_array_string = rtrim($post_array_string,'&'); 
//set the url, number of POST vars, POST data 
curl_setopt($ch,CURLOPT_POST,count($post_array)); 
curl_setopt($ch,CURLOPT_POSTFIELDS,$post_array_string); 
$response = curl_exec($ch);

</conversion> 
</conversions> 
</conversion_response> 

실제로 페이지에 conversion_id와 price 만 표시해야합니다. 다른 결과가 페이지에 표시되는 것을 원하지 않습니다. 어떻게해야합니까?

Answer 1

당신은 당신이 원하는 요소를 얻기 위해 SimpleXMLElement을 사용할 수 있습니다

$xml = new SimpleXMLElement($response); 
echo "<pre>"; 
echo $xml->conversions->conversion->conversion_id, PHP_EOL; 
echo $xml->conversions->conversion->price, PHP_EOL; 

출력

221D4853 
15.0000
