Aahmed: I wrote the book in advance of PHP 5 being final. There were namespaces in the betas of PHP 5, but they were removed a few weeks before the book was published. There was no opportunity to fix the chapter. I did note this in preface, but it’s easy to miss.

namespace?? in section 6.14 you talked about namespace in php5… where is that coming from? I tried several times running php script with namespace… it returns error. i couldn’t find any reference that php5 has name space… what am i doing wrong???

Hi,
It is about listing 24-6 in CorePhp3edition.
It sends an empty file.

Thank.

Terry: I can’t think of an easy, simple way to do what you’re asking. Someone may have written functions that take arrays and turn them into images using the GD library. Or you might find a command-line utility that renders HTML into images that you could shell out to from PHP.

I looked through the book for an example of what I want to do but could not find it. I would like to be able to display a large table generated from mysql
and php as an image of what would be normally displayed by the html
that php generates. Is there an easy way to do this? I am using the html
table function to create a large table with a border. I want the png or
jpg image to look the same as the html table.

Zulfiqar: your function is missing something that my example has, namely a check that the variable (count) is set. If you try to increment a variable that doesn’t exists, whether it’s PHP 4 or PHP 5, you should expect to get an error message.

Dear Leon,
I just started reading your PHP 5 Core Programming book, I found it usefull for me… but as well as i am at the starting..i found some bugs in your coding and one error in programming… following are the details..

1. Mis-printing (may be in my side…)
on page number 87, you have defined three functions, which are:
1. func_get_arg
2. func_get_args
3. func_num_args
it is written further that you will find these in Chapter 8, but these functions are not available in Chapter 8, but instead, these are available in Chapter 11 on page number 412-414.

2. Error in programming…(function is not working)
following function which is on page number 86, listing 4.8 is given error…
————————————————————-
function printColor($text, $color=”black”, &$count=NULL)
————————————————————-
Error is:
“Parse error: parse error, unexpected ‘=’, expecting ‘)’ in C:\FoxServ\www\arg2.php on line 2″

But regarding to this i mean referencing variable, i wrote my own little function with one arguments…(variable reference)
following is an example:

this one is working when $count=0, but not working with &$count=NULL OR &$count=0, giving me same error as i mentioned above…

please inform me about that…
I will be very thankfull to you…

thinking you…
