Question

我有一个处理电子邮件并将其移动到另一个文件夹的脚本。它目前工作正常，但我希望能够在执行imap_mail_move()之前测试我想要将电子邮件移动到的文件夹是否存在。有这么快的方法吗？

$hostname="{".$imap_details['imap_server']."}INBOX".$imap_details['imap_path'];
$imap = imap_open($hostname, $imap_details['email'], $imap_details['imap_password']);
$processed_folder="INBOX/Processed";
//*** I would like to check if the above folder exists here ****
//And then do some processing here
//And then move the email to the processed folder
imap_mail_move($imap,$i,$processed_folder);

Answer 1

$folder = 'INBOX/Processed';
$cstr = '{server.foo.com:993/ssl}';
$imap = imap_open($cstr, ...);
$list = imap_list($imap, $cstr, "*");

if( array_search($cstr.$folder, $list) === false ) {
  die("no folder!");
}

Answer 2

array_search（）返回数组中元素的键。

if（array_search（$ cstr。$ folder，$ list）===＆＃34; -1＆＃34;）{

 die("no folder!");

}

Answer 3

我认为没有理由使用array_search代替in_array。

$folder = 'INBOX/Processed';
$cstr = '{server.foo.com:993/ssl}';
$imap = imap_open($cstr, ...);
$list = imap_list($imap, $cstr, "*");

if (in_array($cstr . $folder, $list))
  exit("No such folder!");
