php多维数组循环相加问题，如下 大神们

$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'),
);

如何把上面数组变成下面的结果
结果：GZYX 3 2 1 3

Answer 1

不知道你jxs的逻辑是上面情况，你可以自己添加代码
$arr = array(array('id'=>7363,'fd'=>1,'fb'=>1,'tcp'=>0,'fbdh'=>1,'jxs'=>'GZYX'),array('id'=>7412,'fd'=>1,'fb'=>0,'tcp'=>1,'fbdh'=>1,'jxs'=>'GZYX'),array('id'=>7512,'fd'=>1,'fb'=>1,'tcp'=>0,'fbdh'=>1,'jxs'=>'GZYX'),);$fd=null;$fb=null;$tcp=null;$fbdh=null;$jxs=null;foreach($arr as $r){$fd+=$r['fd'];$fb+=$r['fb'];$tcp+=$r['tcp'];$fbdh+=$r['fbdh'];//$jxs的逻辑根据你的情况添加}echo $jxs. ' '.$fd. ' '.$fb. ' '.$tcp. ' '.$fbdh;

Answer 2

$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'),
);
$test=array('fd'=>0,'fb'=>0,'tcp'=>0,'fbdh'=>0,'jxs'=>'');
$test['jxs']='GZYX';
for($i=0;$i<count($arr);$i++){
     $test['fd']+=$arr[$i]['fd'];
     $test['fb']+=$arr[$i]['fb'];
     $test['tcp']+=$arr[$i]['tcp'];
     $test['fbdh']+=$arr[$i]['fbdh'];
}
 
print_r($test);
