php - fatal error : Call to undefined function imap_open() in PHP

Question

我正在尝试通过我的本地主机访问我的 gmail 帐户。但是，我收到了回复:

Fatal error: Call to undefined function imap_open()

这是我的代码:

$hostname = '{imap.gmail.com:993/imap/ssl}INBOX';
$username = 'myid@gmail.com';
$password = 'mypassword';

/* try to connect */
$inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Gmail: ' .imap_last_error());

很简单，在您的 PHP 安装中没有激活 IMAP 扩展。不是enabled by default .如果您的本地安装在 Windows 上运行 XAMPP，您必须按照 XAMPP FAQ 中的说明启用它。 :

Where is the IMAP support for PHP?

As default, the IMAP support for PHP is deactivated in XAMPP, because there were some mysterious initialization errors with some home versions like Windows 98. Who works with NT systems, can open the file "\xampp\php\php.ini" to active the php exstension by removing the beginning semicolon at the line ";extension=php_imap.dll". Should be: extension=php_imap.dll

Now restart Apache and IMAP should work. You can use the same steps for every extension, which is not enabled in the default configuration.
