Got this function...
I wanna remove 90 days from todays date, giving a final date, in the same
format as the original, that counts back 90 days...
I'm listing dates on a reporting tool, and I've been asked to only show
info that we recieved in the last 90 days...
Anyhoo...
I believe I can minus 10 days from $day by having...
$timestamp = mktime (0,0,0,$month,$day-10,$year);
But is there an easy was to calculate 90 days from the timestamp...
My worry is that I need to calculate how many days in a month, and then
work out hown many days to remove from that month... etc..
it's all getting far more complicated that it needs to be, and I can't
believe I'm the first person to try and do this...
My code is below, and if anyone would like to offer advse, I welcome it...
=======================
$today = date("Y-m-d");
function minus90($calc){
$year = substr($today, 0, 4);
$month = substr($today, 5, -3);
$day = substr($today, 8, 10);
$timestamp = mktime (0,0,0,$month,$day,$year);
return strftime ("%Y-%m-%d", $timestamp);
}
$archive_date = minus90($today);
echo $archive_date;
