我想从 Gmail 帐户检索最后 10 条消息并将其显示在页面中。到目前为止我有以下内容：
<!DOCTYPE html>
<html lang="en">
<head>
<link href="css/bootstrap.min.css" rel="stylesheet">
<!-- <!--[if lt IE 9]>
<script src="//html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
<link href="css/styles.css" rel="stylesheet">
<!--<link rel="stylesheet" href="mail.css"/> -->
</head>
<body>
<?php
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);
/* connect to gmail */
$user = '*****';
$password = '*********';
$mailbox = "{imap.gmail.com:993/imap/ssl}INBOX";
?>
<?php
$mbx = imap_open($mailbox , $user , $password);
/*imap_check returns information about the mailbox
including mailbox name and number of messages*/
//$check = imap_check($mbx);
/* grab emails */
$emails = imap_search($mbx, 'SINCE "10 Mar 2015"');
/* if emails are returned, cycle through each... */
if($emails) {
/* begin output var */
$output = '';
?>
<table class="table table-bordered table-hover">
<tr>
<th>From</th>
<th>Date</th>
<th>Subject</th>
</tr>
<?php
/* for every email... */
foreach($emails as $email_number) {
/* get information specific to this email */
$overviews = imap_fetch_overview($mbx,$email_number,0);
/*imap_fetch_overview returns an overview for a message.
An overview contains information such as message subject,
sender, date, and if it has been seen. Note that it does
not contain the body of the message. Setting the second
parameter to "1:n" will cause it to return a sequence of messages*/
//$overviews = imap_fetch_overview($mbx,"1:{$check->Nmsgs}");
?>
<?php
/* put the newest emails on top.Doesnt work.*/
// rsort($overviews);
rsort($overviews);
print_r($overviews);
foreach($overviews as $overview)
{
?>
<tr>
<td><?php echo $overview->from; ?></td>
<td><?php echo $overview->date; ?></td>
<td><a href="open.php?id=<?php echo $overview->uid; ?>"><?php echo $overview->subject; ?></a></td>
</tr>
<?php
}
}
}
?>
</table>
</body>
</html>
我在这里看到一篇文章How can I sort arrays and data in PHP? 但我很难理解如何对 $overviews[date] 进行排序。该排序或任何其他排序不工作。如何指定要对 [date] 属性进行排序。谢谢。
PS这里是数组：
Array ( [0] => stdClass Object ( [subject] => Fwd: A Short Course STI #4653 [from] => Fran ***8olo [to] => Fran ****lo [date] => Tue, 10 Mar 2015 12:42:46 GMT [message_id] => <-7376330247335926430@unknownmsgid> [size] => 28928 [uid] => 1532 [msgno] => 743 [recent] => 0 [flagged] => 0 [answered] => 0 [deleted] => 0 [seen] => 0 [draft] => 0 [udate] => 1425991366 ) )
使用 usort 更新代码：
<?php
/* grab emails */
$emails = imap_search($mbx, 'SINCE "10 Mar 2015"');
/* if emails are returned, cycle through each... */
if($emails) {
/* begin output var */
$output = '';
?>
<table class="table table-bordered table-hover">
<tr>
<th>From</th>
<th>Date</th>
<th>Subject</th>
</tr>
<?php
/* for every email... */
foreach($emails as $email_number) {
/* get information specific to this email */
$overviews = imap_fetch_overview($mbx,$email_number,0);
/*imap_fetch_overview returns an overview for a message.
An overview contains information such as message subject,
sender, date, and if it has been seen. Note that it does
not contain the body of the message. Setting the second
parameter to "1:n" will cause it to return a sequence of messages*/
//$overviews = imap_fetch_overview($mbx,"1:{$check->Nmsgs}");
?>
<?php
/* put the newest emails on top.Doesnt work.*/
// rsort($overviews);
usort($overviews, function($a1, $a2) {
$v1 = strtotime($a1['date']);
$v2 = strtotime($a2['date']);
return $v1 - $v2; // $v2 - $v1 to reverse direction
});
print_r($overviews);
foreach($overviews as $overview)
{
?>
<tr>
<td><?php echo $overview->from; ?></td>
<td><?php echo $overview->date; ?></td>
<td><a href="open.php?id=<?php echo $overview->uid; ?>"><?php echo $overview->subject; ?></a></td>
</tr>
<?php
}
}
}
?>
</table>
当我检索电子邮件时仍然得到随机排序。
您可以在 php 中使用 USORT
usort($overviews, function($a1, $a2) {
$v1 = strtotime($a1['date']);
$v2 = strtotime($a2['date']);
return $v1 - $v2; // $v2 - $v1 to reverse direction
});
