Dynamically Adding Hours to a Date in PHP

Manipulating dates and times is a common task in web development. PHP provides a number of functions for working with dates and times, one of which is the date() function.

The date() function takes a format string as its first argument and returns the current date and time formatted according to the specified format. For example, the following code returns the current date and time in the format "Y-m-d H:m:s":

<code class="php">$now = date("Y-m-d H:m:s");</code>

Adding Hours to a Date

Sometimes it is necessary to add a number of hours to a date or time. This can be achieved using the strtotime() function. The strtotime() function takes a date string as its first argument and returns a timestamp representing the specified date and time.

To add a number of hours to a date or time, we can use the following syntax:

<code class="php">strtotime("+{$hours} hours", $timestamp);</code>

where $hours is the number of hours to add to the specified date or time and $timestamp is the timestamp representing the original date or time.

Example

Let's say we want to add 5 hours to the current date and time. We can use the following code to do this:

<code class="php">$now = date("Y-m-d H:m:s");
$new_time = date("Y-m-d H:i:s", strtotime("+5 hours", strtotime($now)));</code>

The $new_time variable will now contain the current date and time plus 5 hours.
