php imap 邮件 排序,PHP imap_sort 用法 手册 | 示例代码

Hello,

We used MIME and NLS libraries in our previous code(imap_locale_sort) that

are part of PEAR and Horde projects, and so our function

was so specific. Here is the general (pure php) code for this

function:

function imap_locale_sort($stream,$criteria,$reverse,$locale,$options)

{

if ($criteria!=SORTSUBJECT)

return (imap_sort($stream,$criteria,$reverse,$options));

$unsorted = array();

$sortresult = array();

$MC=imap_check($stream);

$MN=$MC->Nmsgs;

$overview = imap_fetch_overview($stream,"1:$MN",0);

$k=0;

while( list($key,$val) = each($overview))

{

$unsorted[$k]["uid"]=$val->uid;

$unsorted[$k]["subject"]=imap_utf8($val->subject);

$k++;

}

usort ($unsorted, create_function('$a,$b','setlocale(LC_ALL,$locale);return strcoll($a["subject"],$b["subject"]);'));

for ($m=0;$m

array_push($sortresult,$unsorted[$m]["uid"]);

if ($reverse)

$sortresult = array_reverse($sortresult);

return $sortresult;

}

Sample usage:

$mbox = imap_open("{localhost:143}INBOX.sent-mail","userid","password");

if ($mbox)

echo ("Connection Successful!");

$sorted = imap_locale_sort($mbox,SORTSUBJECT,0,'fa_IR',0);

print_r($sorted);

print ("nn");

$sorted = imap_sort($mbox,SORTSUBJECT,SE_UID);

print_r($sorted);

imap_close($mbox);
