The PHP Functions Essential Reference is a simple, clear and authoritative
function reference that clarifies and expands upon PHP's existing
documentation.The authors have spent time evaluating all of the PHP functions
and have selected the essential functions to include in the printed book. This
includes around 900 of the 1500 functions. The remaining functions will be
covered in the same depth and treated in the same way, but they will appear on
the newriders.com web site along with the content of the entire book, which is
provided under the OPL.
