if dateline NOT greater than TODAY?

[stryka]

What is the PHP if i want to create a logic that finds if the stored DATELINE value is older than 7days... when compared to the current date...

Assuming you mean exactly seven days or older (i.e., not seven days starting at midnight today):

PHP Code:

if ($dateline < time() - (60 * 60 * 24 * 7)) 

60 seconds per minute, 60 minutes per hour, 24 hours per day, 7 days.
