Three errors, not noted in your errata for Core PHP 3 -
(1) pg 369 – typo – middle page – “coverts” s/b “converts.”
(2) pg 1059 typo – “file_exits” s/b “file_exists.”
(3) pg 106 listing 6.1 – the constructor refers to “$this->accesses++;” but accesses is not a property. Add $accesses to the private properties.

VERY useful book!

Page 424 indicates that the function:

array str_word_count(string text, integer mode)

returns an associative array in which the words are keys and the values are the positions. However, as illustrated in Figure 12.2, the associative array returned actually uses the positions as the keys and the words as the values.

Listing 9.27on page223 does not function correctly on a Windows XP system with PHP 5.0 installed on an Apache 2.2 as a module. The problem is that the value of PHP_OS is “WINNT”. Thus the correct fix or statement for line 4 should be:

if(eregi(“winnt”, PHP_OS))

or, better yet:

if(eregi(“win”, PHP_OS))

to satisfy either case and assuming the original line:
( if(eregi(“windows”, PHP_OS))

works for other versions or configurations.

On page 948, Listing 26.11, lines 13-15, the $_REQUESTs need to be converted with intval() so mktime() will accept them as integers, rather than strings.

Thanks for the great book, the best one I have read as yet. Very comprehensive, including many topics not covered in other PHP books. Immensely helpful. Thankyou.

On page 109 of the Core PHP Programming 3rd Edition, The second to the last paragraph says “The class counter is incremented in the constructor and decremented in the constructor.” Should this be “…decremented in the destructor”?

I think this is a really great book. It has helped me a great deal.

Thanks!
