How Can I Add Days to a Date in PHP?

Adding Days to a Date

When attempting to increment a date by a specific number of days, it is crucial to utilize the correct syntax. In PHP, the built-in functions strtotime and date play vital roles in date manipulation.

To address the issue presented in this question, the strtotime function should be employed primarily for parsing dates rather than modifying them. For date addition, the date function offers a straightforward approach.

The code snippet provided in the question attempted to add days using the operator along with the strtotime function:

$date = strtotime(date("Y-m-d", strtotime($date)) . " +".$i."days");

However, this approach returns a numerical representation of the date as a Unix timestamp instead of a formatted date string.

The solution lies in leveraging the date function to accomplish the task. Here's the corrected code:

echo date('Y-m-d', strtotime("+30 days"));

In this code:

• strtotime(" 30 days"): This constructs a Unix timestamp representing 30 days from the current date.
• date('Y-m-d', ...): This formats the timestamp as a string in the "YYYY-MM-DD" format.

Remember to review the official PHP documentation for strtotime and date to grasp their functionalities and syntax:
