function add_member_data($id, $fname, $lname) {
$data = array(
    "ID" => $id,
    "First Name" => $fname,
    "Last Name" => $lname,
);

array_push($all_members, $data);

echo "<pre>";
var_dump($data);
echo "</pre>";

echo "<pre>";
var_dump($all_members);
echo "</pre>";
}

我有这个代码，但是数组推动似乎不起作用。谁能帮忙？

原文

function add_member_data($id, $fname, $lname) {
$data = array(
    "ID" => $id,
    "First Name" => $fname,
    "Last Name" => $lname,
);

array_push($all_members, $data);

echo "<pre>";
var_dump($data);
echo "</pre>";

echo "<pre>";
var_dump($all_members);
echo "</pre>";
}

i have this code but array push doesn't seem to work. Can anyone help?

因此，这里的信息数量非常有限 -
但是，要使此功能正常工作，需要从函数中访问$ all_members变量[并且需要调用函数]。

这是我如何做的一个示例：

$all_members = [
   ["ID" => 1, "Firsn Name" => "Edyth", "Last Name" => "Hammes"],
   ["ID" => 2, "Firsn Name" => "Maye", "Last Name" => "Gerhold"],
];

function add_member_data(&$all_members, $id, $fname, $lname) {
   $data = array(
      "ID" => $id,
      "First Name" => $fname,
      "Last Name" => $lname,
   );

   array_push($all_members, $data);

   echo "<pre>";
   var_dump($data);
   echo "</pre>";

   echo "<pre>";
   var_dump($all_members);
   echo "</pre>";
}

add_member_data($all_members, 3, "Jane", "Smith");

so there is a very limited amount of information here -
but to get this to work there needs to be access to the $all_members variable from within the function [and the function needs to be called].

here is an example of how I would do it:

$all_members = [
   ["ID" => 1, "Firsn Name" => "Edyth", "Last Name" => "Hammes"],
   ["ID" => 2, "Firsn Name" => "Maye", "Last Name" => "Gerhold"],
];

function add_member_data(&$all_members, $id, $fname, $lname) {
   $data = array(
      "ID" => $id,
      "First Name" => $fname,
      "Last Name" => $lname,
   );

   array_push($all_members, $data);

   echo "<pre>";
   var_dump($data);
   echo "</pre>";

   echo "<pre>";
   var_dump($all_members);
   echo "</pre>";
}

add_member_data($all_members, 3, "Jane", "Smith");
