Functional Functions
Summary
In this chapter you created a simple working PHP extension and learned the steps necessary to build it for most major platforms. In the coming chapters, you'll add to this extension, ultimately including every type of PHP feature.
The PHP source tree and the tools it relies on to compile and build on the many platforms it supports is constantly changing. If something in this chapter failed to work, refer to the php.net online manual under Installation to see if your version has special needs.
