Chapter 26. Working with Dates and Times

Most web applications must deal with the date or time at which something happensfor instance, when a user was created, when a transaction occurred, or how long it has been since a user has logged in to an account. As this chapter explains, between the operating system, our database servers, and PHP itself, these dates and times are represented and manipulated in a number of ways.

Throughout this chapter, we will investigate

• How dates and times are represented in code

• How web applications represent and manipulate time

• How to convert time and date formats

• How to output user locale-and language-specific dates and times
