Yes, they are superfluous in this example, but not because we're in 
double quotes.  You can ONLY use complex strings inside double quotes, 
AFAIK:

";// echos blah
echo '{$str}';  // echos {$str}
?>
As I'm sure you're aware, the use of the {braces} is to allow complex 
combinations of variables, like found in the manual 
http://www.php.net/types.string

In the above example, they are indeed not needed, but I've gotten into 
the habbit of using them on all strings for a few reasons;

- the fact that there can be no confusion (either human or PHP) over 
what I mean
- PHP will be non-greedy when looking for the valid variable name
- since i'm now in the habbit, I never have to debug examples where it 
IS needed :)


However, I hate single quotes around HTML attributes, so I can't bring 
myself
to use that format anyway. :-)
Well, that's where we come down to personal opinion... personally, 
seeing \" 100's of times in a script doesn't turn me on at all :)

Which is why I didn't complain about that. :-)

You had your closing tr on the same line. That was not related to spacing
concerns, I assume.

Here is how I WOULD have written that line had it been in my own code.
(Minus some CSS that could be put in.)

echo "\n"
." \n"
."  $somevalue\n"
." \n"
."\n";

In an effort to avoid confusing people that don't know any better
"layout design" means everything except forms and data.

p.s. And yes Curt you touched on why I put my 's all on one
line. Some browsers (I know IE does) like to add whitespace if the 
and  are not all on the same line.

5. no newline after the tr. :)

There are some broswer issues with tr and td's not being on the
same line.  But I guess that shouldn't matter much cause tables
shouldn't be used for layout design.

I agree with you, actually. The only things I don't like are:

1. The use of the bgcolor attribute
2. The name of the variable :-)
3. The fact that your td is not tabbed in
4. The closing tr being on the same line

But, everyone has different tastes. I tend to choose whichever format makes my
HTML look perfect while requiring the least amount of syntax in PHP.

Whoops my bad, for some reason I saw those single quotes as string
delimiters, which really makes no sense on my part at all. I'm claiming
the "just woke up" excuse :)

I remember reading somewhere re: PHP coding that it is a better coding
practice to use single quotes as much as possible vs. using double quotes in
scripts. When using double quotes, you are forcing PHP to look for variables
within them, even though there may not be any, thus slowing execution
time...
For example it is better to code:
 Code:
 echo ' ';
vs.
 Code:
 echo " ";
Better is a very subjective question; however, style 1 will run faster
since it won't look for variable interpolation. Personally I always use
style 1 unless I specifically need variable interpolation or one of the
special characters such as a newline. Also when doing HTML the double
quotes fit nicely in the the single quote paradigm. On the other hand
when I do SQL queries, I often allow interpolation just because it is
more readable and because I usually use single quotes to wrap strings in
my queries.


Now what is wrong with doing this?

echo ' '."\r\n";

That way you can still use your single quotes and still being able to use
the \r\n.. that does work doesn¹t it?  Im pretty sure I have used it
before..
Anyways I guess the point is that you are not forced to use double quotes
for the full echo just so you can use the special newline characters..

"Better" is a very loose term, but I've adopted a coding style which 
uses single quotes on all lines which don't require special characters 
(\n, \t, etc) or variables.

At the same time, I dropped double quotes within my HTML where 
possible, realising that most of my echo's had double quotes, so I was 
escaping a lot of quotes.

I also adapted wrapping all variables in {parenthesis} so that PHP has 
no chance of being confused

On all but the most heavily visited sites, it's my humble opinion that 
you should take the approach of what's fast for you to code, read, 
maintain and re-develop, rather than what might get you a .0001 
% performance gain -- this is most likely due to the nature of the 
sites I develop -- but this seems to be the general consensus I've read 
over many years and from many sources.

No special chars or vars:
echo ' ';
For cases with vars and special chars, I think these look terrible:
echo ' ';
echo " ";
Whereas this is clear and easy to work with:
echo " ";
You mileage will vary, but unless you're working on a hugely successful 
site (the kind that needs a dedicated server), take your personal 
preferences, and long-term readability and maintainability into account 
when deciding what suits you.

[Nathan Taylor]

I am a recent fan of the single-quotes.  I used to use double only but when some gurus 
told me the disadvantages I converted my entire project over to single quotes.  Single 
quotes are ideal because as far coding goes it greatly decreases the time of 
development when you don't have to worry about dropping in the escape character on 
your HTML values, etc.  Granted, single quotes can be a nuisance in some instances 
(like when you need a new line character) but of course there is a way around.  I 
simply define a constant and call that at the end of every line in order to substitute 
for the new line character.

Horizontal Tab - define("T", chr(9));
New Line - define("NL", chr(10));

Cheers,
Nathan

  Better is a very subjective question; however, style 1 will run faster
  since it won't look for variable interpolation. Personally I always use
  style 1 unless I specifically need variable interpolation or one of the
  special characters such as a newline. Also when doing HTML the double
  quotes fit nicely in the the single quote paradigm. On the other hand
  when I do SQL queries, I often allow interpolation just because it is
  more readable and because I usually use single quotes to wrap strings in
  my queries.

  HTH,

I remember reading something very very similar from one of the main php 
developers.. However, for the life of me, I can't remember where it was 
exactly...

I remember reading somewhere re: PHP coding that it is a better coding
practice to use single quotes as much as possible vs. using double quotes in
scripts. When using double quotes, you are forcing PHP to look for variables
within them, even though there may not be any, thus slowing execution
time...
For example it is better to code:
 Code:
 echo ' ';
vs.
 Code:
 echo " ";

You will not be able to measure the difference until you have a zillion of
them...

Why not?!

It's *FAR* more important than raw performance 90% of the time!

Optimize the code that's slow, don't try to write all code at maximum
performance.

If we really needed all code at maximum performance, we'd all still be
coding in binary.

Because the difference is going to be undetectable, this would probably 
be a question that only someone really familiar with the engine would be 
able to answer with any sort of assurance.

My bet is that the second method is faster in theory, because switching 
in/out of PHP is likely marginally faster than executing the echo 
function. Maybe if you create some scripts that loop through these 
statements 10,000 times each and measure the time with microtime(), you 
can get a more affirmative answer and let the list know your results.

Happy hacking.

The difference is very marginal.  Write whichever makes more sense in the
context.  Short tidbits just don't matter.  Larger stretches of text are
easier to just send out as is rather than echo.

Re: [PHP] PHP code optimization

I'm just guessing but I would think there would be no difference.  The only
way I think there would be a differnce is if you did many many echo
statements as opposed to one echo or one ?>output block

[PHP] PHP code optimization

[Peter Thoenen]

Question on optimizing code for quicker runtimes. 
Which is quicker (this is on a webpage also..NOT
commandline)?



OR

 abc 

Both do the same thing and are legit but wondering
which is better from an optimization standpoint (NOT
interested in readability or *proper* code here)

[PHP] code optimization

[Christian Dechery]

I just got (1:30 AM) something that was really annoying me.

I had to do it... but I got so into the "I must do it" thing I ended up 
doing it in an "unoptimized" way, I think.
I got to this conclusion for the amount of loops I'm using and the number 
of lines of code.

The problem is in my previous mail "help with  nasty recursive algorithm"...

I'm using 5 for(;;) loops, and it took 68 lines of code (including 3 small 
functions) to achieve it... it's kinda of too much, don't you think???
