I am having trouble retrieving some data out of an LDAP attribute in PHP.
I connect to LDAP, perform my query, and store the results in a var like so:
$info = ldap_get_entries($connect, $sr);
Now, I can store most of the LDAP attributes I need in sessions vars, like so:
$_SESSION['accountFirstName'] = $info[0]['givenname'][0];
$_SESSION['accountLastName'] = $info[0]['sn'][0];
$_SESSION['accountEmail'] = $info[0]['mail'][0];
These work fine.. No problems. However, there is another var I need to store. I believe It is an associative array. For some reason, no matter what I do, I am getting an NOTICE: Undefined index
warning for that specific attribute. I have tried storing it like the above demonstration, but to be honest I'm not entirely sure what the [0] indices on either ends of the attribute name mean.. I'm not familiar with LDAP and frankly the setup is very confusing.
So I guess my questions are:
how do you access associative arrays that are returned from an LDAP query?
what does 'undefined index' mean? Does it mean that that attribute does not exist, or it does not exist at the index provided?
How can I test my LDAP query to see if the variable even exists?
There is a possibility that the account performing the query does not have adequate LDAP access privileges (the project is for a university and there is a lot of red tape). Is there any way for me to verify that through code?
Thank you! And my apologies for the vagueness of the information provided, I can't be too open-mouthed right now.
