比较日期（“Y-m-d h：i：s”）;

Question

how can I make a conditional statement like if date("Y-m-d h:i:s"); is more than 30 seconds after date("Y-m-d h:i:s");.

I've previously used something like date("Y-m-d h:i:s"); < date("Y-m-d h:i:s"); + 30, however this doesn't seem to work.

Help?

Use strtotime() to convert them to UNIX time.

E.g.:

if(strtotime($date2) - strtotime($date1) > 30) {
    // $date2 is more than 30 seconds after $date1
}

or

if(abs(strtotime($date2) - strtotime($date1)) > 30) {
    // $dates are more than 30 second apart
}
