如何使用curl獲取數組的鍵值（php）

我想使用API但它會打印很多信息，我不知道如何獲得數組的幾個關鍵值。如何使用curl獲取數組的鍵值（php）

<?php 
$query = "SELECT * FROM kvk WHERE adres='Wit-geellaan 158'"; 
$host = "http://api.openkvk.nl/php/"; 
$url = $host ."/". rawurlencode($query); 

$curl = curl_init(); 
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt($curl, CURLOPT_URL, $url); 
curl_setopt($curl, CURLOPT_HEADER, 0); 

curl_exec($curl); 

curl_close($curl); 
?>

是我的PHP腳本，它顯示

array(array("RESULT"=>array("TYPES"=>array("int","bigint","varchar","varchar","varchar","varchar","varchar","int","int","smallint","smallint","int"),"HEADER"=>array("id","kvk","bedrijfsnaam","adres","postcode","plaats","type","kvks","sub","bedrijfsnaam_size","adres_size","verhuisd"),"ROWS"=>array(array("1303095","271242250000","Schoonmaakbedrijf Regio","Wit-geellaan 158","2718CK","Zoetermeer","Hoofdvestiging","27124225","0","23","16","0")))))

在此先感謝

問候， Vierri

//Use the cURL setting to put the result into a variable rather than printing it  
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 

//store the result rather than print (as we set CURLOPT_RETURNTRANSFER) 
$result = curl_exec($curl); 
if ($result === false){ 
    //something went wrong, handle the error 
} 

//evaluate the array result and store it. (Please don't use this line in production code) 
//as the $result string is from a untrusted source 
eval('$array = '.$result.';'); 

//then you can, for example, get a list of the types 
$types = $array[0]['RESULT']['TYPES']; 


//or some keys 
$keys = array_keys($array[0]['RESULT']);

上面的代碼是危險，可能不應該使用，因爲它是。他們可以在響應中加入任何令人討厭的東西，你會評估它（eval行），這可能會對服務器造成不良影響。我會檢查他們是否有更好的API，不會以該格式發送回覆。（JSON或XML效果會更好）

如果沒有，你可能需要手動considerer解析響應數組，而不是使用eval

您好日Thnx您的回覆，解析錯誤：語法錯誤，在/var/www/clients/client5/web6/web/test.php(20意想不到的$結束）：eval（）函數就行'd碼1 警告：array_keys（）[function.array-keys]：第一個參數應該是第27行的/var/www/clients/client5/web6/web/test.php中的一個數組。是我在使用時得到的錯誤eval – x4tje 2010-03-31 12:03:25

@Vierri修復了代碼。 – Yacoby 2010-03-31 12:23:34

是的，它是真正的工作謝謝你的幫助。 – x4tje 2010-03-31 12:37:39

要獲得所有鍵和值：

$server_output = curl_exec($curl); 
var_dump($server_output);

先手鍵列表：

$server_output = curl_exec($curl); 
ksort($server_output); 
foreach ($server_output AS $key => $val) { 
    echo "$key\n"; 
}

的響應是一個字符串不是一個數組。 'ksort'和'foreach'需要數組。 – Yacoby 2010-03-31 12:02:34
