删除超过特定月份的文件

Question

I create that script:

$zips = glob("*.zip");

usort($zips, function($a, $b) { return filemtime($a) - filemtime($b); });

$dateFile = date("F d Y H:i:s", filectime($zips[0]));
$dateNow = date("F d Y H:i:s");

echo "dateFile = " . $dateFile;
echo "<br />";
echo "dateNow = " . $dateNow

Output is:

dateFile = August 03 2017 10:23:47
dateNow = August 03 2017 10:43:27

I want to check if file is older that month a.k.a dateNow - dateFile ? in months?

Answer 1

You do it like the following

if(strtotime(dateFile) < strtotime('first day of last month', time())) {
   //file is older than 1 month
}

You can also use the function for 30 days from now. This will check if the file is older than 30 days backwards from the time you will do this condition.

if(strtotime(dateFile) < (time()-2592000)) {
   //file is older than 1 month
}

2592000 are 30 days in seconds.
