Warn user if IMAP SSL support is not present

[nomadicjosh]

I am testing this plugin on a localhost install. I am trying to setup an email account using gmail but I keep getting the follow error: "Unknown error while connecting to the IMAP server. Please check your IMAP settings and try again."

This is what I retrieved from the local server error logs:

[14-Aug-2014 02:22:47 UTC] PHP Warning: imap_open(): Couldn't open stream {imap.gmail.com:993/ssl} in /Applications/MAMP/htdocs/wordpress/wp-content/plugins/supportflow/classes/class-supportflow-email-accounts.php on line 334

Can someone help me troubleshoot this? Thanks.

Never mind. I see that imap-ssl is not installed on MAMP.

Thanks for the report @parkerj, we should probably do a better job of warning users if imap-ssl isn't installed.

@VarunAgw, can you add an error message specifically for this situation, so that they don't see the generic one?

From what I think it might be caused by IMAP extension not build with SSL support. Because if extension was not installed it will have given fatal error.

Now the best thing I found to check if it is support SSL so far is using new ReflectionExtension('imap')->info(); But it returns the data along with other information in a table.

Opinions?

Something like this should work:

ob_start();
$imap_info = new ReflectionExtension('imap');
$imap_info->info();
$imap_info = strip_tags( ob_get_clean() );
$ssl_enabled = false !== strpos( $imap_info, 'SSL Support enabled' );

oh wait..I think imap_errors() must have also given the same error. So I guess it is better to use it.

But I can't reproduce it.
