訪問JSON值

Question

我試圖訪問一個JSON請求的各個部分，一個典型的反應是：

{ 
    "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個數據在1分的foreach循環而不是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']; 
    } 
} 
?> 

上面的代碼工作正常，但我真的需要訪問「UrlFrom」，並使用1個foreach循環「錨」值（如果可能的2層的foreach的上面稍微當添加到數據庫中時，將其放入我的實時項目中會很複雜），我們將不勝感激。

有了一個的foreach，

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