difference from dates

[Davide]

Hi all.

I'm looking in php.net a function that helps me to work with date.

I need to build a script wich can calulate the difference from a
specific date "2007-03-01" to current date.
I'm thinking about unix epoch, is it the correct way?

example:

2007-03-05 - 2007-03-01 = 2 days
2007-03-05 - 2007-02-05 = 1 month
etc...

Calculate the difference in seconds (using the Unix epoch) and convert
that to days, weeks, months.

$old_date = strtotime('2007-03-01');
$now_date = time();
$date_diff = $now_date - $old_date;
printf( "Date difference is %.2f seconds (%.2f days).\n",
$date_diff,
$date_diff/(24*60*60) );

Hmmm, in most calendar systems, 2007-03-05 - 2007-03-01 would be 4 days,
not 2 days...
