制作一个数组键=>从另一个数组添加值

Question

我想要这个数组输出，因为我需要它供 PHP 中的 Google_service_calendar_event 的参与者使用：

   Array ( 
         [0] => Array ( [email] => myemail@gmail.com ) 
         [1] => Array ( [email] => myemail1@gmail.com )
         [2] => Array ( [email] => myemail2@gmail.com )
         [3] => Array ( [email] => myemail3@yahoo.com ) ) 

这是我的 PHP 代码：

    $invitados_inicial = array(array('email' => $correo_del_director));

    foreach ($_SESSION['gcal_correo_aplicantes'] as $correo_aplica) {

        $invitados_inicial['email'] = $correo_aplica;
    }

这就是我得到的（不是我需要的）：

    Array ( 
        [0] => Array ( [email] => myemail@gmail.com ) 
        [email] => Array ( 
            [0] => myemail1@gmail.com 
            [1] => myemail2@gmail.com 
            [2] => myemail3@yahoo.com
        ) 
    ) 

无论如何，我没有得到我想要的输出数组，我的与会者也无法进入 Google_service_calendar_event。我应该怎么做才能获得我不想要的数组输出？

Answer 1

你必须弄清楚$_SESSION['gcal_correo_aplicantes'] 的结构才能得到正确的答案。在下面，我假设它是这样的：

$session = array( "email1@add.com","email2@add.com");

第一个解决方案：

<?php
$invitados_inicial=[];
for ($i=0; $i<count($session);$i++) {
    $invitados_inicial[$i] = array( 'email' => $session[$i] );
}
var_dump($invitados_inicial);

第二个选项：

<?php
$invitados_inicial=[];
foreach ($session as $correo_aplica) {
    $invitados_inicial[] = array( 'email' => $session[$i] );
}
var_dump($invitados_inicial);

Answer 2

感谢您的帮助，您给了我一些想法，我可以这样做：

    $invitados_inicial = array(array('email' => $correo_del_director));

    // Agrego a los candidatos seleccionados a listado de participantes      
    foreach ($_SESSION['gcal_correo_aplicantes'][0] as $correo_aplica) {

      $invitados_inicial[] = array('email' => $correo_aplica);
    }

感谢 Jarbit Lira 和 Carlos E. López，他们也给了我很多帮助。

试试这个：

 $invitados_inicial = array(array('email' => $correo_del_director));

        foreach ($_SESSION['gcal_correo_aplicantes'] as $correo_aplica) {

             foreach ($correo_aplica as $value) {
               $arr['email'] = $value;
               $invitados_inicial[] =  $arr;
           }
        }
