Chapter 3. Arrays, Strings, and Advanced Data Manipulation in PHP
In the previous chapter, we introduced the basics of the PHP
language. In this chapter we show you some important techniques
you'll need to manipulate data in PHP. This includes
ways of dealing with arrays, strings, dates, and numerical data. The
topics in this chapter cover:
Arrays and array library functions Strings and string library functions Regular expressions Date and time functions Integer and float functions
We don't attempt to cover every function and library
supported by PHP. However, we provide brief descriptions of them in
Appendix E. In later chapters, we discuss
selected specialized library functions that support the topics and
techniques presented here.
