Subject: [PHP] File handling and different character sets
Hi,
I would like to know how you work with the PHP Directory Functions and
different character sets. If I am having a professional view,
well-written code should be able to handle file systems in different
character sets.
http://se.php.net/manual/sv/ref.dir.php
Is there a way to write code for listing files from a ISO-8859-1 on a
UTF-8 page? I haven't succeeded with this.
Thank you,
Best Regards
Per Eriksson

Hi Per,
I'm just curious, no matter what encoding I choose (IE and FF switch
automatically to UTF-8 as per the page metatag and content-type header) I
get funny characters at http://se.php.net/manual/sv/ref.dir.php, I don't
know if this is because of the default browser font, because I've tried
several ones. My system is Windows XP SP2 Spanish version, but I don't think
that's the cause either as it is up to date, and I have even installed
support for right to left writing...
Ok, I know I can just use wget, save the result and open it in a binary
editor to see what are the actual bytes and check for the encoding (I
won't... I'm kind of lazy today :D )
Regarding your question, I have these functions I copied from the notes to
the extended CHM version of the PHP manual, they are at the
mb_convert_encoding function reference and should be in the online version
of the manual as well (won't check it... too lazy, I told you)...

Hey guys. For everybody who's looking for a function that is converting an
iso-string to utf8 or an utf8-string to iso, here's your solution:
public function encodeToUtf8($string) {
return mb_convert_encoding($string, UTF-8, mb_detect_encoding($string,
UTF-8, ISO-8859-1, ISO-8859-15, true));
}
public function encodeToIso($string) {
return mb_convert_encoding($string, ISO-8859-1,
mb_detect_encoding($string, UTF-8, ISO-8859-1, ISO-8859-15, true));
}
For me these functions are working fine. Give it a try
[/snip]
The first thing to test for would be if the directory/filesystem functions
are retrieving data encoded in ISO-8859-1 or not (I guess it depends on the
OS, but you might know better), otherwise mb_convert_encoding would act like
double escaping or double urlencoding (a known issue for all of us,
ha?). That's why encodeToUtf8 uses mb_detect_encoding first... anyway, I
wonder if mb_detect_encoding can guarantee you anything other than the byte
stream of data being valid in the given character set(s). So... what do you
think, did you get any further results about this? And also, do you have any
code sample you are working on to share?

Rob

Re: [PHP] File-handling
fgets uses the resource created by fopen.
Read the manual:
http://it.php.net/fopen
http://it.php.net/fgets
look at the example:
?php
$handle = fopen(/tmp/inputfile.txt, r);
while (!feof($handle)) {
$buffer = fgets($handle, 4096);
echo $buffer;
}
fclose($handle);
?

[EMAIL PROTECTED] wrote: Hi there! Can someone explain the major difference between fgets and fopen? Which is the best together with plain textfiles? and why? fgets can be handy to read a large file one LINE at a time. This is most useful in files that are line-based, such as SQL data dumps, CSV files, text files, config files, etc. when you want to process their contents a line at a time and do something to the data. fget lets you read an arbitrary amount of data -- this is useful if you just want to transfer the data from point A to B without interpreting it, or if the data is binary and has some sort of internal byte-structure you need to tear apart to process it. For small files, you might as well just use http://php.net/file or other functions that deal with the whole file at once -- You only really want to mess with fopen/fget|fgets/fclose if you have files that could potentially be HUGE, and you can read a chunk at a time, deal with it, and read some more -- Avoiding trying to suck the whole thing into RAM all at once. When using fget. Is it something special you should think when taking care of line-breaks? (/n, /r/n ...) If your data could potentially be coming from Mac, PC, and/or Linux instead of just one platform, you'll have to write some code to figure out what to do with line-breaks. Since I'm always on Linux servers, I generally do: $data = str_replace(\r\n, \n, $data); //PC - Linux $data = str_replace(\r, \n, $data); //Mac - Linux This converts everything to Linux format, which is what I'll use internally. Note that the order of the two lines is crucial -- If you flip-flop them, you'll make a real mess. If you're not trying to change the data, nor interpret it, you needn't worry about the newlines. eof and feof. What's the difF? *don't get it* EOF is an acronym for End Of File. feof is the function used to determine if a file has reached its EOF -- that is, if you have successfully read all of the data, and there is no more data to read, and the file still seems kosher, so you're DONE. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

How do i delete all file in a directory???
You could use a function like this:
(html code at end)
function delFiles($filter, $sDir) {
$cDirectory = includeTrailingSlash($sDir);
$handle = opendir($cDirectory);
while ($file = readdir($handle))
{
if ($file == '.' || $file == '..')
{
continue;
}
if (is_dir($cDirectory . $file))
{
echo ignoring $cDirectory$file br /;
delFiles($filter, $cDirectory . $file);
continue;
}
if (eregi($filter, $file))
{
echo emdeleting $cDirectory$file/em br /;
unlink($cDirectory . $file);
}
}
closedir($handle);
}
function includeTrailingSlash($path)
{
if (!eregi(/$, $path))
{
$path .= /;
}
return $path;
}
// delete all the .htm files in this directory and it's sub directories
$sDir=the directory you want to delete files in;
delFiles(\.htm$, $sDir);
//where\.htm$ is the filter you are applying
echo done deleting old files br /;

Re: [PHP] File handling
I've got this coed but it still don't do the business:
$MESSAGE_FILE=foobar.txt;
$handle=fopen($MESSAGE_FILE,w);
$sizez= sizeof($handle);
$string= 'foo';
while ( fgets($handle,$sisez)
{ fputs($handle,$sizez);
if (strstr($handle,$string)){
break;
}
}
Any ideas?

And what happens if there are more than one occurrence of foo? I assume you mean the first occurrence. And what happens if foo is found within another word, like aafooaa... this example assumes this doesn't matter... it's looking for 'foo', not ' foo '. One of way is to read the file into a variable, split the var on foo, and rewrite the file out. ? $split = 'foo'; $file = 'dummyfiles/01-04-29.php'; // get file contents $fd = fopen ($file, r); $mytext = fread ($fd, filesize($file)); fclose ($fd); // split it on $split, append $split to first chunk list($prefix,$suffix) = split($split,$mytext); unset($suffix); $newtext = $prefix.$split; // write to file $fp = fopen($file, 'w'); fwrite($fp, $newtext); fclose($fp); ? 1. Totally untested code, but most of it was lifted out of the manual in some way or another. 2. Permissions of the file to be read/written will need to be correct 3. I've included no error reporting or correct checking... you'll need to add this yourself Season to taste...

Re: [PHP] File handling
loop through the file line by line explode()ing every line with TEXt in it. Then, if retrning array count is bigger than one, unset() the key one and break the loop.
