访问JSON值

Question

我试图访问一个JSON请求的各个部分，一个典型的反应是：

{ 
    "Overview" : { 
     "firstresultposition" : 1, 
     "totalresultsreturned" : 2, 
     "linkpop" : "2", 
     "domainpop" : "2", 
     "netpop" : "1", 
     "ippop" : "1" 
    }, 
    "Results" : [ 
     { 
     "Links" : [ 
      { 
       "UrlTo" : "http://www.eclecticaartisans.com/", 
       "Anchor" : "Eclectica Artisans' Shop", 
       "nofollow" : "0" 
      } 
     ], 
     "IP" : "64.14.78.39", 
     "Index" : 1, 
     "DomainRank" : "5", 
     "UrlFrom" : "http://www.shoppernews.com/directory.html" 
     }, 
     { 
     "UrlFrom" : "http://shoppernews.com/directory.html", 
     "DomainRank" : "4", 
     "Index" : 2, 
     "IP" : "64.14.78.39", 
     "Links" : [ 
      { 
       "UrlTo" : "http://www.eclecticaartisans.com/", 
       "Anchor" : "Eclectica Artisans' Shop", 
       "nofollow" : "0" 
      } 
     ] 
     } 
    ] 
} 

我想要做的就是2个数据在1分的foreach循环而不是2本：

<?php 
$returnSK = file_get_contents("REQUEST_URL"); 
$seoKicks = json_decode($returnSK, true); 
print "<pre>"; print_r($returnSK); print "</pre>"; 
foreach ($seoKicks['Results'] as $key => $val2) { 
    echo $val2['UrlFrom']; 
    foreach ($val2['Links'] as $arr) { 
     echo $arr['Anchor']; 
    } 
} 
?> 

上面的代码工作正常，但我真的需要访问“UrlFrom”，并使用1个foreach循环“锚”值（如果可能的2层的foreach的上面稍微当添加到数据库中时，将其放入我的实时项目中会很复杂），我们将不胜感激。

有了一个的foreach，

foreach ($seoKicks['Results'] as $key => $val2) { 
    echo $val2['UrlFrom']; 
    echo $val2['Links'][0]['Anchor']; 
}
