Submitted by argie on Thursday, March 6, 2014 - 15:32.

This tutorial will teach you on how to add days in a date using PHP. I uses PHP strtotime to add days to the current date. This tutorial is useful for thus creating a system that needs a reservation using a range of date. Follow the steps bellow to learn this tutorial.

Creating Our Form

Tis code will display our form with the current date and a textbox that allow you to input the number of days you want to add in your current date. Copy the code bellow and save it as "index.php".

<form action="index.php" method="GET">
<span style="display: inline-block; width: 150px;">Date</span><input type="text" name="date" required="required" value="<?php echo date("m/d/Y") ?>" /><br>
<span style="display: inline-block; width: 150px;">Number of days</span><input type="text" name="numberofdays" value="<?php echo $nd ?>" autocomplete="off" /><br>
<span style="display: inline-block; width: 150px;">Result</span><input type="text" name="result" value="<?php echo $result ?>" /><br>
<span style="display: inline-block; width: 150px;">&nbsp;</span><input type="submit" value="Calculate" />
</form>

Creating Our Script That add Days to Date

Copy the code bellow and paste it above our form in "index.php".

<?php 
if (isset($_GET["date"])) { $date  = $_GET["date"]; } else { $date=date("m/d/Y"); }; 
if (isset($_GET["numberofdays"])) { $nd  = $_GET["numberofdays"]; } else { $nd=0; }; 
$result=date('m/d/Y', strtotime($date. ' + '.$nd.' days'));
?>
