Appendix B. Additional New Features and Minor Changes

This appendix covers the changes made in PHP 5 that aren't documented elsewhere in the book. Some sections discuss new features, such as the command-line processing options. Other sections contain slight modifications of existing features, such as what happens when you incorrectly treat a string as an array, or how strrpos ( ) handles its needle. These fixes will trip you up if you're relying on PHP 4 behavior.
