how to check if a date is three days before today

Question

Hey i would like to know if there is any script (php) that could check if a specified date three days before today.

say..

$d1 = date("Y-m-d", filemtime($testfile));
$d2 = date("Y-m-d");

now i would like to know how to compare this two dates to check if d1 is atleast 3days ago or before d2 any help would be gladly appreciated.

Answer 1

Why not to use DateTime object.

 $d1 = new DateTime(date('Y-m-d',filemtime($testfile));
 $d2 = new DateTime(date('Y-m-d'));
 $interval = $d1->diff($d2);
 $diff = $interval->format('%a');
 if($diff>3){
 }
 else {
 }

Answer 2

Assuming you wish to test whether the file was modified more than three days ago:

if (filemtime($testfile) < strtotime('-3 days')) {
   // file modification time is more than three days ago
}

Answer 3

Just check it with timestamp:

if (time() - filemtime($testfile) >= 3 * 86400) {
  // ...
}

Answer 4

use date("Y-m-d", strtotime("-3 day")); for specific date

you can also use

strtotime(date("Y-m-d", strtotime("-3 day")));

to convert it to integer before comparing a date string
