Determining the Hour Difference between Dates in PHP

You're looking to calculate the hour difference between two dates, which are formatted in "Y-m-d H:i:s."

To achieve this in PHP:

1. Convert the Dates to Timestamps:

   Timestamps represent the number of seconds since January 1, 1970, at midnight, in your server's time zone. To convert dates to timestamps, use the strtotime() function:

   <code class="php">$timestamp1 = strtotime($date1);
   $timestamp2 = strtotime($date2);</code>

   Salin selepas log masuk

2. Calculate the Hour Difference:

   Subtract the earlier timestamp from the later timestamp and divide by 3600 to get the hour difference:

   <code class="php">$hourdiff = round(($timestamp1 - $timestamp2) / 3600, 1);</code>

   Salin selepas log masuk

   The round() function is used to avoid having a lot of decimal places.
