title: inner join CSV values in string format to MySQL table in php
body: <p>I have an array of email addresses that I need to verify against a DNC table. Fairly simple in theory- ready for the twist? I cannot make a temp table. Nor do I wish to issue a SELECT statement for each email. Wouldn't it be unsightly to chain 'OR' statements? I would imagine relatively inefficient. Anyone see a clean, efficient way of going about this?</p>
