Connect to Gmail with PHP & IMAP
提问by Makis
I have enabled OpenSSLand IMAPfunctions from my php.inifile and phpinfo()confirms it.
我已经从我的文件中启用OpenSSL和IMAP运行php.ini并phpinfo()确认它。
By using the code below i can connect to a Hotmail account but not to a Gmail account.(of course i change the $connect_toto point to Hotmail.)
通过使用下面的代码，我可以连接到 Hotmail 帐户，但不能连接到 Gmail 帐户。（当然我将其更改$connect_to为指向 Hotmail。）
$connect_to = '{imap.gmail.com:993/imap/ssl}INBOX';
$connection = imap_open($connect_to, $user, $password)
or die("Can't connect to '$connect_to': " . imap_last_error());
imap_close($connection);
The returned error is
返回的错误是
Warning: imap_open(): Couldn't open stream {imap.gmail.com:993/imap/ssl}INBOX in /opt/lampp/htdocs/webmail_client_practise/index.php on line 6
Can't connect to '{imap.gmail.com:993/imap/ssl}INBOX': Certificate failure for imap.gmail.com: unable to get local issuer certificate: /C=US/O=GeoTrust Inc./CN=GeoTrust Global CA
Notice: Unknown: Certificate failure for imap.gmail.com: unable to get local issuer certificate: /C=US/O=GeoTrust Inc./CN=GeoTrust Global CA (errflg=2) in Unknown on line 0
Unfortunately i cannot find a complete tutorial of how to use the IMAP functions.
不幸的是，我找不到有关如何使用 IMAP 功能的完整教程。

If you get blocked, this can be because google sees a login from a new device.
如果您被阻止，这可能是因为 google 看到了来自新设备的登录信息。
Go to your google account and check https://myaccount.google.com/device-activityand let them know the 'Unknown device is ok to use'.
转到您的 google 帐户并检查 https://myaccount.google.com/device-activity并让他们知道“可以使用未知设备”。

First check your date and time settings on your server are correct.
首先检查您服务器上的日期和时间设置是否正确。
Alternatively try:
或者尝试：
$connect_to = '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX',
This will stop it from trying to validate certificate.
这将阻止它尝试验证证书。
I will probably get downvotes from people telling me this is bad practice as this leaves you open to Man in the Middle attacks. Which is true.
我可能会从那些告诉我这是不好的做法的人那里得到反对票，因为这会让你对中间人攻击持开放态度。这是真的。
