Added strlen functions to error_log as follows:


Both string lengths are reported to be 70 but should be 60.

Haven't found any problems yet with character encoding in the tables/columns but am I going in the right direction now?

The password recordset was returning HTML special characters. The following addition fixed it...

$stored_password= html_entity_decode($stored_password, ENT_QUOTES | ENT_HTML5, 'UTF-8');

Looks to be working fine now. Posting this to help others in the future, and possibly myself when I forget this workaround!

This would automatically remove any encoding:
$stored_password= $Recordset1->getColumnVal("Password",false);
