strtotime（）没有返回适当的时间

Question

I'm having trouble getting strtotime() to work correctly.

For starters, Here's my goal: I'm trying to set it up that you can only create an article every 5 minutes.

To accomplish this I've got

    strtotime('5 minutes')<strtotime($lastcreate)

this code ^^ in my file.

   <?php
        echo '<ul><li>' . strtotime($lastcreate) . '</li>';
        echo '<li>' . strtotime("now") . '</li></ul>'; ?>

Outputs:
1392203323
1392228579

$lastcreate is stored in my database as now()

When i use this code to call it. The numbers differ by like 7 hours.

Does anybody know why it does this and/or a better way to go about doing this?

Answer 1

Here is what you are looking for, ways to set your timezone to match in both PHP and MySQL and the correct comparison.

PHP

date_default_timezone_set('America/New_York');

MySQL Query Run Before Your Query

SET time_zone = 'US/Eastern'

Your PHP Comparison

if(strtotime('now') >= strtotime($lastcreate . ' +5 minutes')){
    // its been more then 5 minutes since the last post
}
