I ran some tests, and did the following:
$Order_Total = sprintf("%01.20f",$Order_Total);
$Refund_Amount = sprintf("%01.20f",$Refund_Amount);
which produced:
$Order_Total = 102.84431566

$Bar = 102.85;
$Foo = sprintf("%01.20f",$Bar);
echo "\$Foo = $Foo";
which produced:

Re: [PHP] Coordenates latitude / longitude on PHP - SOLVED
It wasn't so hard!
I ll post the solution, so everyone ll be able to do it
function getlocationcoords($lat, $lon, $width, $height)
{
$lat=$lat*20;
$lon=$lon*28;
$x = (($lon + 180) * ($width / 360));
$y = ((($lat * -1) + 90) * ($height / 180));
return array("x"=>round($x),"y"=>round($y+3500));
}
$lat -> Latitude
$lon -> Longitude
$width -> Image's width (Where u are going to represent the data)
$height -> Image's height (Where u are going to represent the data)
This is the zoom of the data
$lat=$lat*20;
$lon=$lon*28;
If the data is lo flat (for example), u can fix it writting bigger
values on the data that is multiplying.
$x = (($lon + 180) * ($width / 360));
$y = ((($lat * -1) + 90) * ($height / 180));
This translates lat / lon to cardinal data. I found it on the net.
return array("x"=>round($x+VALUEONE),"y"=>round($y+3500));
If u puts the rights values on VALUEONE or 3500, u will be able to
center the coordenates on the image.
Done!

Re: [PHP] GetText string not found
Is strange that there is not a really good solution for this problem, i
think its not very strange. Maybe i ll request this feature, I think is
interesting, useful and not so hard to add.
Anyway, I cannot use "ob_ " functions, i ll have problems with some
functions.
So, the solution seems to extend "_" function, that provides me the
posibility to report "strings" not found.
The bad think is that I ll have to make thousands of modifications in
order to implement this feature in the webpage :(

My experience, if you call it that, with gettext consists of reading
the manual and saying "Neat!", so take this with a HUGE grain of
salt...
One option that MIGHT work would be:
function ___ ($string) {
//check for existince of the language file/string by hand :-(
}
Another option, perhaps, would be to have your "default" language be
something really... weird, and then the output itself would be icky...
I suppose you could do something hacky like:
All code/html here.
Ugh.
Maybe a Feature Request at GetText and/or bugs.php.net would be in
order...

[PHP] OPTIMIZING - The fastest way to open and show a file

time opening the file. (Im using 2.6.9-1.667smp and XFS)
* For files less or equal 6 Kb, takes arround 0.02-0.03 miliseconds - its ok
* For files arround 35 Kb takes arround 0.2-0.4 miliseconds - too much.
What can I do to make faster opening files?
**
Source code:
if(file_exists($filename)){
$modified_date=filemtime($filename);
if(time()<($modified_date+1 * 24 * 60 * 60)){
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);
echo $contents;
}
}
**
Thinks that I have tried:
* fopen is *much* faster than include
* filemtime is faster than filectime
* Pear Cache its too much slower (0.5-0.7 milsecond per file)

if(file_exists($filename)){
$modified_date=filemtime($filename);
if(time()<($modified_date+1 * 24 * 60 * 60)){
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);
echo $contents;
}
}
Checking both file_exists and then doing fopen seems a bit silly.
Trap the error from fopen, and just use that as your file_exists test.
I suspect http://php.net/file_get_contents will be SLIGHTLY faster
than doing all of this code, though:
if (filemtime($filename) > time()) $contents =
@file_get_contents($filename);
if ($contents === false){
//error-handling code
}
else{
echo $contents;
}
Then, of course, we have to wonder if you NEED $contents for later use
in the script.
If not, something like this will clock in better:
$bytes = @readfile($filename);
if ($bytes === false){
//error-handling code
}
This seems to be the best solution. I do not need $content anymore. I ll
post results. :)
The difference here is that you don't even stuff the file into the PHP
string. It's all read and passed out to stdout in low-level internal
PHP C code, and the data never needs to hit "PHP" variables which are
"more expensive" to setup and maintain.
Note that which is REALLY fastest will probably depend on the size of
the files, your OS system cache, your hardware, and maybe which
version of PHP you are using, if the underlying functions changed.
Must be nice to be worried about 0.0x milliseconds -- I'm fighting a
mystery 3.0 seconds in a data feed for a search engine myself :-)
Search engine ... thats the most complicated!

Re: [PHP] OPTIMIZING - The fastest way to open and show a file
:(
Its not working
$bytes = @readfile($filename);
if ($bytes === false){

[PHP] High load Forum?
Hi, Im looking for a good forum thats supports high load. (Now between 300-2.000 active sessions, much more in next 2 years) I have heard about vBulletin and PhpBB.

I wouldn't "forget" Netscape, because people still use it. Just make sure your code validates to W3C standards and so long as it isn't too cutting edge, must browsers should display it fine. To answer your question, Opera is probably the third most popular browser on Windows.

Re: [PHP] PHP Cache (was PHP load to high on server)
Did u tried memcached? http://www.danga.com/memcached/ Albert wrote: I wrote: I am running SuSE 9.2 (Kernel 2.6.8-24-default) with Apache 2.0.50 and PHP 4.3.8 (as an Apache module) on a Celeron 900 with 304MB RAM. This machine is used for testing. We have made some changes to our PHP application and now the machine is having trouble serving the pages. Apache is occupying almost 90% CPU usage. I have resolved this issue by removing a piece of code which reads a set of parameters from a database. It seems that the hard disk on the machine is quite slow, slowing down all database access with it... I now check if the parameters are set in the session, if it is I use them otherwise I read them from the database and save it as session variables. When it changes I simply remove it from the session so it forces an update. So far it is working quite well. I now want to go and take all the static stuff that the user will configure once in a life time and put it in the session and only update it when it changes instead of reading it from the database every five seconds or so. For this I don't want to use a disk based session handler. I want the session variables to remain in memory (about 20KB per user) as to speed up the whole process. I also want an opcode cache to cache the compiled pages on the server in an attempt to speed up the HTTP server. For this I wanted to use mmCache (actually I want to use Zend Performance Suite but first I need to prove that it is worth $ 1000 per CPU and from the stats on the mmCache site mmCache is faster...) but it seems that the mmCache project has been abandoned as there have been no work done on it since 2003. Can someone confirm this or recommend an alternate cache (doesn't have to be free but should break the bank) which will do what I want?
