Hi,
You are right but this might cause some data error in last block of file but my problem is that i have file changing data in whole entire of my file. Let ignore last block, in other block we shoud have any problem in converting file towice but there is some problem.
This code in c++ working well but in php i don't know what happen if I accesing my data with index ([$i]) and change it with xor operation it looks that my original data will be growup.
thanks

Hi,
I looked a bit closer, here is your code again, then my comments:
1 define('BUFSIZ', 4095);
2 $url = $_GET["addr"];
3 $msk = $_GET["key"];
4 $msklen = count($msk);
5 $rfile = fopen($url, 'r');
6 $lfile = fopen(basename($url), 'w');
7 while(!feof($rfile))
8 {
9 $content = fread($rfile, BUFSIZ);
10 while($i=0; $i < BUFSIZ; $i++)
11 $content[$i] = $content[$i] ^ &msk[$i % count($msk)];
12 fwrite($lfile, $content, BUFSIZ);
13 }
14 fclose($rfile);
15 fclose($lfile);
1.
your code does not compile, there are several mistakes.
2.
line 10 is wrong; a while statement takes one argument, you intended to use a for loop?
3.
line 11: &msk needs a dollar sign, not an ampersand.
4.
line 11: you can't silently convert a character to an integer; when you want the ASCII index of a character, use the ord function[^]. The reverse operation is performed using the chr function[^].
Finally, here is some code that might help you:
function par($string) {
echo "<p>$string</p>\n";
}
function hexdump($title, $filename1) {
$BUFSIZ=20;
$hex="0123456789ABCDEF";
$dump="";
$rfile = fopen($filename1, 'r');
$content = fread($rfile, $BUFSIZ);
$len=strlen($content);
for($i=0; $i < $len; $i++) {
$val=ord($content[$i]);
$dump=$dump." ".$hex[$val/16].$hex[$val%16];
}
par("");
par($title);
par($dump);
}

I wouldn't worry about a PHP currency converter, but about the missing keyboard-keys, if I was you.

Currently I'm develop an application same as CRM. To generate report in PDF,i'm using FPDF as my tools. The problem is, to retrieve the data from database,I create temporary file e.g:dldata.php and call that page in my pdf viewer file. U can access the data and easily view the actual data(if you know the address).By using explode(),I retrieve the data and display it on my pdf viewer page. The dldata.php will be delete (using unlink()) after user load the quotation form. Below are the flow to create quotation in pdf:
fill form data(createquotation.php)->insert data to database->create session,dldata.php & write data into it from mysql->redirect page to viewquotation.php(here I call dldata.php)->click print quotation or back to createquotation.php & destroy dldata.php. Anyone that have experience using FPDF to advise me about this issue. I'm afraid the conflict arise when 2 or more users doing the same process at the same time. TQ.

What is your actual problem?
Creating the PDF File?
or
Downloading the PDF File?
|
|
|
|
|
I have no problem with either download or creating the pdf file. The problem is method that i used. I used this code to call dldata.php after i create it.
$pdf = new PDF();
$header = array('Product ID', 'Product No', 'Product Description', 'Subtotal#39;);
// Data load from the file and it will be=>1;#13,21321;Pencil;$1.00
$data = $pdf->LoadData('dldata.php');
I followed tutorial based on fpdf official website.
Tutorial:
http://www.fpdf.org/en/tutorial/tuto5.htm[^]
Example for dldata.php shape of data:
http://www.fpdf.org/en/tutorial/countries.txt[^]
After load back to the createquotation.php,I destroy dldata.php file. I'm afraid, it will be issue if more than 2 user do this process at the same time. It will be last in,first out. Only The last data store will be appear. Can I just use dldata.php without delete it and call the data without any user can access it by type the url.

Hi,
Just have set of around 100 xml files that need to be displayed on HTML.
Each file consists of same 40 elements and then sub elements as well. While looking for the best way to display the xml in html - i found w3s solution i.e.
http://www.w3schools.com/xml/xml_to_html.asp[^]
But this process is quite cumbersome. I mean, if i go with this process, I have to enter all the elelments and sub elements name and then only i can get that to display my xml in html.
Is there any other way, that can read the xml file itself and display each elements and sub elements in html ??
Thanks
Andyyy

You might want to look into using XSLT for translating your XML into something HTML friendly.

yes, php has a new (to me) class you can read about it here. http://www.php.net/manual/en/class.domdocument.php[^]
I found it very easy to use on html sources. But if you look in the comments you will see some examples of how xml to html can be done.

Recently had a similar challenge. You might try checking out IBM's site by searching for xml parsing techniques. My files were huge and the solution I worked out performs extremely well and quickly.

It's not experimental software, and they do release a stable build now and then.
You'll find that most stuff is available, up to .NET 4.0. The MonoDevelop IDE doesn't come with a WinForm-designer, you'll have to build your forms from code, or switch to GTK# which would come with a small learning-curve because it works a bit different from WinForms.
