19.2.3 Online help

This is NOT the latest copy of this book; click here for the latest version.

Moving up the food chain, the next most helpful thing is online help for PHP - to be able to jump to a reference in the PHP manual in a click or two means you are never far from an answer. More advanced editors even let you select functions from within your code, and they'll jump straight to the manual entry for them.

Want to see this stuff in print? PHP in a Nutshell takes the core topics covered here, adds in thousands of edits from the editorial team and myself, and combines them to make an unbeatable reference for PHP programmers at all levels.

My latest book has hundreds more tips on how to use PHP, Apache, and MySQL, plus Perl, Python, shell scripts, performance tuning, and more!
