php多維陣列問題

我的多維陣列代碼如下：

$arr = array(                      array('id'=>7363,'fd'=>1,'fb'=>1,'tcp'=>0,'fbdh'=>1,'jxs'=>'GZYX'),     array('id'=>7412,'fd'=>1,'fb'=>0,'tcp'=>1,'fbdh'=>1,'jxs'=>'GZYX'),     array('id'=>7512,'fd'=>1,'fb'=>1,'tcp'=>0,'fbdh'=>1,'jxs'=>'GZYX'),     array('id'=>7516,'fd'=>1,'fb'=>0,'tcp'=>1,'fbdh'=>0,'jxs'=>'BJCJ'), );   //意思就是數組裡面jxs 相同 他們的fd，fb，tcp，fbdh相加 //如何把上面數組變成下面的結果 //結果： GZYX 3 2 1 3 BJCJ 1 0 1 0

----------解決方案------------

7363,'fd'=>1,'fb'=>1,'tcp'=>0,'fbdh'=>1,'jxs'=>'GZYX'),     array('id'=>7412,'fd'=>1,'fb'=>0,'tcp'=>1,'fbdh'=>1,'jxs'=>'GZYX'),     array('id'=>7512,'fd'=>1,'fb'=>1,'tcp'=>0,'fbdh'=>1,'jxs'=>'GZYX'),     array('id'=>7516,'fd'=>1,'fb'=>0,'tcp'=>1,'fbdh'=>0,'jxs'=>'BJCJ'), );   $result = []; foreach ($arr as $a)  {     if (empty($result[$a['jxs']])) {         $result[$a['jxs']] = $a;     } else {         foreach ($a as $k => $v) {             $result[$a['jxs']][$k] += $v;         }     } }   foreach ($result as $k => $r) {     echo sprintf("%s %d %d %d %d\n",                  $k, $r['fd'], $r['fb'], $r['tcp'], $r['fbdh']); }
