Question

php二维数组 有数组如下

Array(
[num] => Array(
[0] => 1111
[1] => 2222
)
[ip] => Array(
[0] => ip1
[1] => ip2
)
)
我想转成
Array(
[num] => Array(
[0] => 1111

)
[ip] => Array(
[0] => ip1

)
)
Array(
[num] => Array(
[1] => 2222
)
[ip] => Array(
[1] => ip2
)
)
该怎么做？

Answer 1

$ar1[num] = ['111','222'];
$ar1[ip] = ['333','444'];
print_r($ar1);

foreach($ar1 as $value1){

print_r($value1);
$num[]=$value1[0];
$ip[]=$value1[1];
print_r($num);
print_r($ip);
}
这段代码把
Array
(
[num] => Array
(
[0] => 111
[1] => 222
)

[ip] => Array
(
[0] => 333
[1] => 444
)

)
分成了
Array num【】

(
[0] => 111
[1] => 333
)
Array ip【】

(
[0] => 222
[1] => 444
)
不知道是不是你想要的。如果你非要再存进二维数组的话崽崽循环外加上
$numnum[num]=$num[0];
$numnum[ip]=$num[1];
$ipip[num]=$ip[0];
$ipip[ip]=$ip[1];
print_r($numnum);
print_r($ipip);
就过就变成
Array
(
[num] => 111
[ip] => 333
)
Array
(
[num] => 222
[ip] => 444
)

Answer 2

$arr = array(
    'num' => array('111','222'),
    'ip' => array('ip1','ip2')
);
$result = array();
       
foreach($arr as $key => $value) {
    $i = 0;
    foreach($value as $data) {
        $result[$i][$key] = $data;
        ++$i;
    }
}
print_r($result);
