If your question really is "how to check smtp connected or not", then the answer is: you did great!

The documentation of imap_open() clearly states that the function returns either a resource or FALSE in case of a failure. So your conditional if ($mbox) reliably checks if the connection was successful.

You could make the condition more readable and explicit though: if (FALSE === $mbox)

but smtp or hostname is connected and i want to show that. but my code alwys display ip not connected when its working – sannrash Jul 01 '15 at 06:20
As said: `imap_open()` reports that the connection failed if `$mbox` resolves to `FALSE` in the condition. Why do you think it succeeded? How do you tell? – arkascha Jul 01 '15 at 06:21
can u please give me a solution for this?? its my assesment – sannrash Jul 01 '15 at 06:22
Sorry, no, I cannot give you a solution, since I do not see an issue here to be solved. I cannot say why your connection attempts fail. – arkascha Jul 01 '15 at 06:23
