Other thing that comes to mind is xdebug which will format error
output - not sure if that ends up in the error log though.

Hey Daevid, does this form <?php echo 'The answer is '.$answer; ?>
improve anything in processing time or it's just for the sake of
readability?
Technically it does have a microscopic speed increase, but unless you're
pumping out hundreds or thousands of lines (like in a loop) you most likely
won't notice it. In my code, I always try to use the proper quote marks
because I *am* dealing with huge tables of data. I've said this a hundred
times before, if you can shave off 0.001 from each row, then after 1,000
rows, you've shaved 1 second off the page time. That seems small, but that
shit adds up. Caching will help, as the page is already parsed once, so PHP
doesn't have to do the work again in many cases. To me, it's a good habbit
and costs you nothing to do.
The difference is that with " the PHP engine has to pre-process the string
and look to see if there's anything interesting it needs to do -- such as
replace any $var with their equivalents or \n or whatever else. A ' means
to use it as is, so PHP just spits it back out.
In my test comparing:
$a = 'The answer is ' .$answer;
vs:
$a = "The answer is $answer;"
I ran numerous test using 10,000,000 (10 million) operations each and
the results never exceed 1/2 of a second difference, usually around
1/3 of a second.
I realize that servers and conditions can change the results, but
these results are what my server produced. I also realize there can
be special conditions where one should consider speed, but seldom is
the case where one needs to be concerned about pre-processing a
string. The likelihood that it will present a problem is extremely
remote. And these results are with today's speeds -- the difference
will be less tomorrow and an order of magnitude less in a couple of
years, or less.
I guess that what I am trying to say is pick considerations that are
significant enough to have real merit. If you can show that your
solution can be significantly improved by doing something a certain
way, then more power to you. However, simply saying one way is better
because it is faster, or uses less memory, doesn't carry the weight
it once did. For example, it would have been nice if the net had been
based on 8-bit instead of 7-bit, but the people who developed ASCII
were concerned about memory. They were right for what they considered
important at their time, but those concerns created a larger problem
for the industry that followed. The significants of concerns change
over time and not realizing that can create problems later.
Cheers,
tedd

I have around 6000 text files and I need to change the first line on every
one of them.
The first line is the title of the article and I need it look like this
<title>the name of the article</title>
every file has the first line and the it starts the article on the second
line
The files are in many directory under one main directory
like this
top directory
fashion-school
Dogs
DentalAssistant
etc..........
I need a script that will loop through each directory look at each file
extract the first line and replace it with the example above.
I have figured out how to pull the first line into an array but I don't no
where to go from there to look in each directory and the write the data back
at the top.
$f = file('GENERAL HISTORY OF DOGS.txt');
$a = '<title>' . $f[0] . '</title>';
echo $a;
