How to Correctly Add Days to a Date in PHP?

Adding Days to Dates in PHP

The task is to manipulate a date returned from a MySQL query (e.g., "2010-09-17") and increment it by a specified number of days. The goal is to create variables like $Date2, $Date3, etc., that represent subsequent dates.

Incorrect Attempt

The user initially tried the following code:

date('Y-m-d', strtotime($Date. ' + 1 day'))

However, this code resulted in the date before the original date.

Correct Solution

To correctly add days to a date in PHP, it is important to use "days" instead of "day" in the strtotime() function. Here's the corrected code:

echo date('Y-m-d', strtotime($Date. ' + 1 days'));
echo date('Y-m-d', strtotime($Date. ' + 2 days'));

Output

This code correctly outputs the subsequent dates:

2010-09-18
2010-09-19
