title: Simplest way to increment a date in PHP?
body: <p>Say I have a string coming in, <code>"2007-02-28"</code>, what's the simplest code I could write to turn that into <code>"2007-03-01"</code>? Right now I'm just using <code>strtotime()</code>, then adding <code>24*60*60</code>, then using <code>date()</code>, but just wondering if there is a cleaner, simpler, or more clever way of doing it.</p>
