I am still working my way through it and may come back and increase my rating of it later on (if possible), but for now I wanted to just mention one really annoying style matter that makes the code samples hard to read (and is the reason I decided to pause and write a review).

This is a typic code sample (I bought the PDF version of the book):


function update_counter () {
static $counter = 0;
$counter++;
echo "Static counter is now $counter\n";
}
$counter = 10;
update_counter();
update_counter();
echo "Global counter is $counter\n";
Static counter is now 1
Static counter is now 2
Global counter is 10


The last three lines are the result of running the code above it. Could that not be distinguished somehow? Could there not be a separator between the code and the results? Or could not a different type style be used? Or even add a line break and say "This results in:" or something like that?

All the samples run the code and results together which make them difficult to read. I was surprised a format like that would be used.
