While trying to read plain mails with imap_fetchbody I want to receive the used charset which can be found in the fetched array grabbed by imap_fetchstructure which can look like :
stdClass Object
(
[type] => 0
[encoding] => 4
[ifsubtype] => 1
[subtype] => PLAIN
[ifdescription] => 0
[ifid] => 0
[lines] => 13
[bytes] => 285
[ifdisposition] => 0
[ifdparameters] => 0
[ifparameters] => 1
[parameters] => Array
(
[0] => stdClass Object
(
[attribute] => CHARSET
[value] => iso-8859-1
)
)
)
The key [parameters] holds the desired value. Unfortunately it can look also like
[parameters] => stdClass Object
(
)
How could I avoid running into a fatal error when asking for
$charsetType = $structure->parameters;
I would need to identify that this time [parameters] is empty and does not hold a value.
Any idea how I could check in this case that this object is empty? I bet it is something simple but I seem to be too tired to grab it...I tried empty() and isset() but both doesnt work as the key is there and not empty (somehow).
