为时间反馈添加秒数

Hey everyone im trying to display relative date and time messages to the user, so for example if the file was updated less then 5 seconds ago the message the user will see is: 'Updated Just Now' however it doesnt seem to be working.

Here is the code that I am using

function relativeTime($date) {
    $timeNow = date('M d Y H:s');

     if ($date == $timeNow || $date == date('M d Y H:s', + 500)) {
         echo "Updated Just Now";

     } else {
         echo "not now";
     }
}

This is where I am displaying it and passing it the argument:

<?php relativeTime(dateUTCtoLocal("M d Y H:s", $arrSchool["updated"]));?>

I eventually will have a few if's in there for minute and hours, am I going about this the right way?

Thanks in advance.

Basically you're looking for if the time it was posted is less than five seconds ago. Easy, but you MUST use timestamps. Formatted times are no good.

relativeTime($arrSchool['updated']); // if it's a numeric timestamp
relativeTime(strtotime($arrSchool['updated'])); // if it's a datetime string

function relativeTime($timestamp) {
    if( $timestamp > time()-5) {
        echo "Updated Just Now";
    }
    else {
        echo "not now";
    }
}

You can convert the input date string into a Unix timestamp using strtotime() and calculate the difference between the input date and current time, and display the message if the difference is less than 5 minutes (5 * 60 = 300 seconds):

function relativeTime($date) {
    $timeNow = date('M d Y H:s');
    $diff = strtotime($timeNow) - strtotime($date);

     if ($diff < (5*60)) {
         echo "Updated Just Now";
     } else {
         echo "not now";
     }
}
