i know you tried to explain it clearly, but i don't completely get it yet.
table1: developer_log
id
company
project
property
email
cc_email
table2: developer
name
project
type
ok, so the 'project' field is the relation between these 2 tables right?
if you wanted all the developer information in each row of the original query, and they were joined on the project, your query might look like this. ( although i'm not sure if this is what you are going for )
Code:
select * from developer_log as dl
left join developer as d on dl.project=d.project
where dl.expiry > '$mktime'
