php LDAP help

[phyang]

hello php community :),

i'm scripting this to talk to my company LDAP server, i'm able to bind the connection successully, but then it does not dump anything out? can you please advise on the scripting if i'm missing anything? port?   I remove the password, username, and ldap connection and so as the ldap_dn  since it's personal. but please advise me on what i'm missing? 

example how i connect:

I can only connect to server with this:
ldap_connect('google.com');

i cannot connect if i reference port as this? should i even reference port at all?

ldap_connect('google.com',3269);  or this ldap_connect('ldaps://google.com:3269');

        // Uh-oh, something is wrong...

        print "CONNECT ERROR<br />";
