How to Detect if time stamp is over a certain time ago

Question

I have the timestamp formatted in the regular way like this:

2012-02-23 20:34:55

I need to detect the following thing.

if(Timestamp >= 1 month ago) {

}

if(Timestamp >= 5 minutes ago) {

}

How would you detect that type of thing from a timestamp variable in PHP?

By the >= I mean if the time stamp has been at least or longer than 5 minutes ago.

Answer 1

First, create a DateTime object from your time string and one for now

$dt = new DateTime($timestamp);
$now = new DateTime;

Then, create some DateInterval objects

$oneMonth = new DateInterval('P1M');
$fiveMinutes = new DateInterval('PT5M');

Then, do your comparisons

if ($dt >= $now->sub($oneMonth)) {
}

if ($dt >= $now->sub($fiveMinutes)) {
}

Answer 2

if (strtotime($timestamp) <= strtotime('-1 month'))
