这种情况FOREACH怎么用

 foreach($str as $key=>$row)<br />	     {<br />		   if(preg_match_all('/\b[Nn][Ss][Kk]-\w{5}/',$sn,$match)){<br />	       $str[$key]['darfon_pn']=substr_replace($match[0][0],$row['darfon_pn'],7,2);<br />		   }else{<br />		   $str[$key]['darfon_pn'] = '';<br />		   }<br />         }

以上代码只遍历了$match[0][0]，如何才能遍历整个$match每个值

------解决方案--------------------
最初的 $str[$key]['darfon_pn'] 的内容是什么？
测试代码

$sn = 'NSK-34582 NSK-UUS89 NSK-89234';<br />preg_match_all('/\b[Nn][Ss][Kk]-\w{5}/',$sn,$match);<br />print_r($match[0]);<br />$str = '________';<br />foreach($match[0] as $v) {<br />  $str = substr_replace($v, $str,7,2);<br />  echo $str,PHP_EOL;<br />}<br />

Copy after login

Array
(
    [0] => NSK-34582
    [1] => NSK-UUS89
    [2] => NSK-89234
)
NSK-345________
NSK-UUSNSK-345________
NSK-892NSK-UUSNSK-345________

是你期望的吗？
