Chapter 6. Strings and Characters of the World

We were introduced to the usage of strings in PHP in Chapters 1, "Getting Started with PHP," and 2, "The PHP Language"; however, there are a number of additional things we must consider when working with them, including how non-English speakers represent the characters of their languages, and how we, as application authors, deal with these.

By the end of this chapter, we will

• Know how PHP manages and stores strings internally

• Know the various character sets and standards in use throughout the world

• Know how to configure PHP to use Unicode internally

• Know about a number of functions that can parse, clean up, and search through strings in PHP
