Hi,
This is a bug/feature in php and is just not possible. Either use the
syntax you've used on the single quotes, or store the variable in a
temporary var before using the print.

Or use printf which is much more readable.

I found that double quoted strings are more elegant in some situations
than single ones, and I like identical solutions for identical problems,
so that's why I asked this question.
But finally found a reason why use single quoted strings instead of double:
because the number of generated opcodes is less in the former case.
Here is a detailed explanation (the url does not exist anymore,
so make a search on the url and load the cashed version of the page):
blog.golemon.com/2006/06/how-long-is-piece-of-string.html
If anyone can run the vld package and share the currently relevant
opcodes, it will be appreciated.

Are you serious about this? How would printf make things more readable?
Given a string with some %s %d etc in it, and then at the end you're giving
the stuff that replaces them. I fail to see how that improves readability
when you can put the variables in the string at exactly the place they are
printed, so the final string can be read as a somewhat normal text.

First of all, I find the url is working fine for me. While it clearly
shows that there are more opcodes generated for a specific method, it does
not show performance difference. These opcodes are virtual opcodes, that
are to be translated by the engine, and there is no guarantee that each
opcode required the same amount of cpu cycles to process, and it could
perfectly be that the instruction with the most opcodes generated is
actually the fastest of all. A real comparison would benchmark this by cpu
cycles instead of number of opcodes.

We do a lot with caching and storing in memecached as well as local copies
so as to not hit the cache pool over the network and we have found some
great tools to minimize our javascript and our css, and now we'd like to
compress our HTML in these cache slabs.
Anyone know of a good tool or even regex magic that I can call from PHP to
compress/minimize the giant string web page before I store it in the cache?
It's not quite as simple as stripping white space b/c obviously there are
spaces between attributes in tags that need to be preserved, but also in the
words/text on the page. I could strip out newlines I suppose, but then do I
run into any issues in other ways? In any event, it seems like someone would
have solved this by now before I go re-inventing the wheel.

How about you just compress it? Gzip, bzip2, etc. Pick your favourite.

Well we already use the gzip compression that is built into Apache since that
works in tandem with the client too.
http://betterexplained.com/articles/how-to-optimize-your-site-with-gzip-compression/
The point of minification is to remove comments, commented sections, optimize
the code by removing closing tags when not needed (</p> or <br/>), strip
unnecessary white space, etc.. there is more to it than just squeezing bits
which is what LZO or GZIP do. They work in conjunction with each other.

Continuing in my effort to port an app from PHP version 5.1.6 to
5.3.3, the app uses this construct all over the place when building
links:
<?=$var?>
I never could find any documentation for this, but I assumed it was
some conditional thing - use $var if it's defined, otherwise use
nothing. In 5.1.6 it seems to do just that. But in 5.3.3 I'm not
getting the value of $var even when it is defined. Has this construct
been deprecated? Is there now some other way to achieve this?

It should still work. You might need to turn on the short tag option
in your conf file.

Sorry, ini file, not conf. Been a long day. :D
I guess I should have asked if short tags are turned on for your 5.3.3?

It is the equivalent of <?php echo $var; ?> it's just easier to type and read
IMHO. For a while people were freaking out that they thought it would be
deprecated, but that is not (nor ever will be) the case.

Ah, I see now. Sorry, I must have read the original question wrong.
There's a good thread on stack about short tags:
"Are PHP short tags acceptable to use?"
<http://stackoverflow.com/questions/200640/are-php-short-tags-acceptable-to-use>
Which kinda links to the docs:
"PHP tags"

Hi guys,
i have a string like this:
$string = \uc548\ub155\ud558\uc138\uc694
(Korean words that say "hello world" in English).
i got no luck when I tried with
Korean. 'UCS-2BE' to 'UTF-8' encoding conversion didn't work. i also
tried with ISO-2022-KR and EUC-KR to 'UTF-8' , but no luck either.
It should be 안녕하세요!
How can I convert that $string to Korean's character?
my regards,
Marco
