如何在php中使用foreach循环创建多维数组？

当我采用数组中的值形式时

$fname = $_POST['first_name'];
$lname = $_POST['last_name'];
$job   = $_POST['job'];
$desc  = $_POST['desc'];
$photo = $_POST['image_url'];

$memberdata = Array(
          'first_name' => $fname,
          'last_name' => $lname,
          'job' => $job,
          'desc' => $desc,
          'image_url' => $photo
          );

它像下面那样回显这个阵列。 如何修改代码以实现目标？ 有没有其他方法可以得到我想要的结果？ 成员表单是使用jquery动态生成的。 我想得到我在下面提到的成员vise数组

Array
(
    [first_name] => Array
        (
            [0] => Member1
            [1] => Member2
            [2] => Member3
        )

    [last_name] => Array
        (
            [0] => Member1
            [1] => Member2
            [2] => Member3
        )

    [job] => Array
        (
            [0] => President
            [1] => MD
            [2] => CEO
        )

    [desc] => Array
        (
            [0] => President of
            [1] => MD of
            [2] => CEO of
        )

    [image_url] => Array
        (
            [0] => 
            [1] => 
            [2] => 
        )

)

如何从上面的数组中生成特定的数组？ 如何修改代码以实现目标？ 这就是我想要的

 Array
(
   [0] => Array
   (
      [first_name] => Member1
      [last_name] => Member1
      [job] => President
      [desc] => President of
      [image_url] =>
   )

   [1] => Array
   (
      [first_name] => Member2
      [last_name] => Member2
      [job] => MD
      [desc] => MD of
      [image_url] =>
   )

   [2] => Array
   (
      [first_name] => Member3
      [last_name] => Member3
      [job] => CEO 
      [desc] => CEO of
      [image_url] =>
   )
)

我猜您的

foreach

循环如下所示：

$result = array();
foreach($members as $member) {
    $result['firstname'][] = $member['firstname'];
    $result['last_name'][] = $member['last_name'];
    //etc
}

$result = array();
foreach($members as $member) {
    $result[] = array(
        'firstname' => $member['firstname'],
        'last_name' => $member['last_name'],
        'job' => $member['job'],
        'desc' => $member['desc'],
        'image_url' => $member['image_url']
    );
}

应该是这样的：

$result = array();
foreach($members as $member) {
    $result['firstname'][] = $member['firstname'];
    $result['last_name'][] = $member['last_name'];
    //etc
}

$result = array();
foreach($members as $member) {
    $result[] = array(
        'firstname' => $member['firstname'],
        'last_name' => $member['last_name'],
        'job' => $member['job'],
        'desc' => $member['desc'],
        'image_url' => $member['image_url']
    );
}

基于示例代码的更新：

POST字段是数组，因此必须确保为每个成员发布所有字段，因为

for

循环基于具有相同值的所有字段

$fname = $_POST['first_name'];
$lname = $_POST['last_name'];
$job   = $_POST['job'];
$desc  = $_POST['desc'];
$photo = $_POST['image_url'];

$memberdata = array();

// we iterate the firstname field and access the same indexes from the other fields. The $i starts with 0 and gets incremented until it iterated over all the firstnames
for($i = 0; $i < count($fname); $i++) {
    $memberdata[] = array(
        'first_name' => $fname[$i], // we access the firstname at the current index
        'last_name' => $lname[$i],
        'job' => $job[$i],
        'desc' => $desc[$i],
        'image_url' => $photo[$i]
    );
}

var_dump($memberdata);

$fname=$\u POST['first\u name']；
$lname=$\u POST['last\u name']；
$job=$_POST['job']；
$desc=$_POST['desc']；
$photo=$\u POST['image\u url']；
$memberdata=array（）；
//我们迭代firstname字段并从其他字段访问相同的索引。$i从0开始递增，直到它遍历所有的名字
对于（$i=0；$i$fname[$i]，//我们在当前索引处访问firstname
“姓氏”=>lname[$i]，
“作业”=>$job[$i]，
'desc'=>$desc[$i]，
'image_url'=>$photo[$i]
);
}
var_dump（$memberdata）；

请添加

foreach

循环PHP代码，您是如何尝试解决此问题的，但没有成功？谢谢@Tumtum，但它只显示空数组，没有其值。我已经编辑了我的帖子，也许你可以从中得到一些想法。
