why the program can't stop after downloaded all the emails?

Question

There are 2465 emails in my gmail,why the program can't stop after download all the emails? All code1 and code2 are run in command line mode.
code1:

<?php $mailbox = array(     'mailbox'  => '{imap.gmail.com:993/imap/ssl}INBOX',     'username' => '[email protected]',     'password' => 'yyyy' );  $stream = imap_open($mailbox['mailbox'], $mailbox['username'], $mailbox['password'])     or die('Cannot connect to mailbox: ' . imap_last_error()); $emails = imap_search($stream,"ALL"); $nums=imap_num_msg($stream); echo $nums; foreach($emails as $email_id) {              $mime = imap_fetchbody($stream, $email_id, "");             file_put_contents("/tmp/" . "email_{$email_id}.eml", $mime);         }  imap_close($stream); echo "over"; ?> 

For code1 :
1.can download all the emails.
2.output 2465 on the console
3.no over output on the console.
4.the program can't stop ,it seems to run forever.

code2:

<?php $mailbox = array(     'mailbox'  => '{imap.gmail.com:993/imap/ssl}INBOX',     'username' => '[email protected]',     'password' => 'yyyy' );  $stream = imap_open($mailbox['mailbox'], $mailbox['username'], $mailbox['password'])     or die('Cannot connect to mailbox: ' . imap_last_error()); $emails = imap_search($stream,"ALL"); $nums=imap_num_msg($stream); echo $nums; foreach($emails as $email_id) {             echo  $email_id.PHP_EOL;             $mime = imap_fetchbody($stream, $email_id, "");             file_put_contents("/tmp/" . "email_{$email_id}.eml", $mime);         }  imap_close($stream); echo "over"; ?> 

For code2:
1.can download all the emails.
2.output 2465 on the console .
3.over output on the console.
4.the program stop after download all the emails.

There is one line echo $email_id.PHP_EOL; in code2 more than code1,other codes are same.
All code1 and code2 are run in command line mode.
Who can explain it ?

Try

print imap_last_error();
