PHP imap_open(): Couldn't open stream to gmail - php

I'm getting this messages when I tried to use php-imap to retrieve emails from server using IMAP protocol. I started with gmail accounts. But when I tried to connect using imap_open() I get the following messages:
Warning: imap_open(): Couldn't open stream {imap.gmail.com/imap/ssl:993}INBOX in \path\to\file\imap.php on line 6
or
Warning: imap_open(): Couldn't open stream {imap.gmail.com/imap/ssl/novalidate-cert:993}INBOX in \path\to\file\imap.php on line 6
depending if I use or not novalidate-cert
I found some related question, but not the solution
imap_open(): Couldn't open stream
Getting Error like imap_open(): Couldn't open stream in server
Connecting to Gmail IMAP PHP "Couldn't open stream"
Is it possible connect to email using the imap php extension?
If, Yes. How can I solved this message?
If, No. Which alternative for received email using PHP could be possible?

Try imap.gmail.com:993/imap/ssl. Port number comes after the domain name and befor the URI path.

PHP imap_errors standard list of error responses

I've successfully tested multiple email server connections. I've also tested the responses when intentionally submitting incorrect credentials (wrong pass word).
Here are the server responses for failed authentication via print_r(imap_errors());:
AOL: imap_open(): Couldn't open stream
{imap.aol.com:993/ssl/imap}Unknown: [AUTHENTICATIONFAILED] LOGIN
Invalid credentials (errflg=1)
Gmail: imap_open(): Couldn't open stream
{imap.gmail.com:993/ssl/imap}Unknown: [AUTHENTICATIONFAILED] Invalid
credentials (Failure) (errflg=1)
Outlook: imap_open(): Couldn't open stream
{imap-mail.outlook.com:993/ssl}Unknown: LOGIN failed. (errflg=1)
imap_open(): Couldn't open stream
{imap-mail.outlook.com:993/ssl}Unknown: LOGIN failed. (errflg=1)
Yahoo: imap_open(): Couldn't open stream
{imap.mail.yahoo.com:993/novalidate-cert/ssl/imap}Unknown:
[AUTHENTICATIONFAILED] LOGIN Invalid credentials (errflg=1)
I also want to be able to test other possible error messages. I looked at the documentation for imap_errors however there wasn't anything useful there.
Each failed authentication response does contain the same string (errflg=1); where can I find the list of these strings so I can test how to handle any other types of errors?
The location of the error in PHP's source code is located at php-src-master\ext\imap\php_imap.c though I'm not familiar with C:
php_error_docref(NULL, E_NOTICE, "%s (errflg=%ld)", ecur->LTEXT, ecur->errflg);

Message: Unknown: Can not authenticate to IMAP server: [AUTHENTICATIONFAILED] Authentication failed. (errflg=2)
Message: Unknown: Retrying PLAIN authentication after [AUTHENTICATIONFAILED] Authentication failed. (errflg=1)
Like gmail server is their any option that i should check or uncheck in hostgator server. or any other method I should used?

imap google with php: couldn't open stream

I'm trying to get emails through a PHP script:
$mbox = imap_open("{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX", "username#gmail.com", "password");
But I'm constantly getting this error:
Warning: imap_open(): Couldn't open stream {imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX
IMap is enabled on my Google Account.
From the server, I tried nmap -p 993 imap.gmail.com and it return that there is imap service under this address.
regards
In my case, this error is caused by the outbound proxy blocking access to port 993.

imap_open(): Couldn't open stream (imap ssl)

I'm trying to read emails from imap mail with the php library ddeboer/imap .
I've created a subdomain like this: abm.mydomain.be . The IMAP extension wasn't installed so I asked the server administrator to install it. The function imap_open now exists. But now I'm getting the following error:
AuthenticationFailedException in Server.php line 76:
Authentication failed for user abm#mydomain.be with error imap_open(): Couldn't open stream {mail.mydomain.be:993/imap/ssl/validate-cert}
The user and passwords are correctly (100% sure of that). When I check phpinfo I see the following with imap:
Does anyone knows what I'm doing wrong?
