cons.php

if($local){
    $var = 'var';
    $foo = 'foo';
    $var1 = 'var1';
    $foo1 = 'foo1';
}else{
    $var = '';
    $foo = '';
    $var1 = '';
    $foo1 = '';
}

/remote/vars.remote.php is the same as vars.php but different values for variables

的config.php

 $local = isset($_SERVER['REMOTE_ADDR']) && ( $_SERVER['REMOTE_ADDR'] === '127.0.0.1') ? 1 : 0;
 if ($local){
      include_once ('vars.php');
 }else{
       include_once('/remote/vars.remote.php);
 }    
 define(CONST_OP_1,$var);
 define(CONST_MAIL_1,$foo);
 define(CONST_OP_2,$var1);
 define(CONST_MAIL_2,$foo1);

mail.php

 require_once "Mail/Queue.php"; 
 include_once ('cons.php');
 $db_options['user'] = CONST_OP_1;
 $db_options['pass'] = CONST_OP_2;
 $mail_options['port'] = CONST_MAIL_1;
 $mail_options['dsn'] = CONST_MAIL_2;

comm.php

 class Sendmail
   {
 ...
function sendc($var){
      require_once ('config.php');
      $mail_queue = new Mail_Queue( $db_options , $mail_options );
 }

...

}

有一些我不理解的东西，我无法弄清楚它为什么会发生。当我执行foreach($array_mails as $email){ $mail_q = $sendmail->sendc($u_name); }和comm.php时，我在ajax function传递和数组但由于一个奇怪的原因，一切都在第一个循环中正常工作但在第二个循环（及其后）处于看来$array_mails文件中的数组似乎没有被声明，所以它给了我一个

注意：$ db_options和$ mail_options的未定义变量。

我知道如何解决这个问题，但我想了解为什么会发生这种情况。有人可以解释一下吗？

Answer 1

您需要将require_once('config.php')更改为require，或者将其放在文件的顶部。

require_once仅允许一次包含文件，因此第二次循环不再包含该文件。

在foreach第二次没有定义函数内部的变量
