Doing maths with strings is normally complicated. PHP provides two 
native formats to handle dates: Unix timestamps and DateTime objects. 
Both allow direct comparison with the "<" operator.

var_dump(new DateTime('2011-03-10') < new DateTime('2011-03-31'));
var_dump(strtotime('2011-03-10') < strtotime('2011-03-31'));

bool(true)
bool(true)
