I get information and put these information into a session variable,
like which language the page should be displayed. I have two frames on
that web page. One is the main page and one is a disclaimer. After a
while the disclaimer and then the main frame starts to fall back to the
default language.
I try from my desktop several browsers and so the information is in
different sessions almost the same.
I am doubting if the frames are the cause of vanishing SESSION information.

Hi
I am in the process of porting a Perl application to PHP and I have hit a snag
with trying to substitute test within a file. I have looked at the PHP manual
and believe I should be using preg_replace but I have tried the examples and am
not getting the result I would expect. I would appreciate any help in getting
this to work.
In Perl I have the following
$html = `cat htmlfile`;
$html =~ s/%ResID/$bookid/g;
which replaces each instance of %ResID with the contents of the variable $bookid
In PHP I have tried
$html = `cat htmlfile`;
$html = preg_replace('%ResID',$bookid,$html);
When I run this I find $html is empty rather than containing the file with the
%ResID replaced with the contents of $bookid.
I would appreciate any help with my understanding of preg_replace.

Delimiters needed. Can use about anything not already in your pattern. "/" is
very commonly used; but I like "#" or "%" generally; but, you can't use "%"
because your pattern has it.
$html = preg_replace("#%ResID#",$bookid,$html);

wont a str_replace() do just fine in this case?
// and we can do backticks too ;-)
$html = str_replace("%ResID", $bookid, `cat htmlfile`);

As Jochem said.
But don't use backticks, use file_get_contents(). It's portable and
you don't start up a new process just to read a file.
$html = str_replace('%ResID', $bookid, file_get_contents('htmlfile'));

Hello,
I have a script that ads data to a html template.
However when there is an include in the html like:
<!--#include file="include/header.sinc" -->
it is not "processed", but "just" ends up as a string in the page.
So I guess it needs to be parsed. Is there an easy way to do that ?
thanks,
Ron

Do you have SSI enable in Apache? You are running Apache right? Do you
have the file named .shtml? Or do you have Apache setup to run SSI
through the HTML parser allowing you to have the files named .html
instead. But I guess the other question is why are you using an SSI
command that you could easily use a PHP command for and thus not have to
mix the two?

Can you just change it to
<?php include('include/header.sinc); ?>
?

Yes I do have SSI enabled
here is what I am doing.
I have a php script that reads (a basic) file with html in it. (meaning
it it would have an html/shtml extension it would just work in a browser.
Now I rename the file to myhtml.dat and let the script read it and print
it to stdout.
That works like a char..... until there's a server side include in the
html page. (ssi's work in both html and in php)
I tried to use <?php include("that.file"); ?> but that doesn't seem to
work

I think the problem is that I read the lines in PHP, I read them with
fgets and output them with printf.
So the php "interpreter" never gets to see the line.
the apache doesn't parse php output, so it doesn't happen there either.
So.. I figured.. I either had to parse it in php myself OR convince
the apache server to parse it for me.

ok I wrote something "quick and dirty" real quick:
But somehow it doesn't seem to like recursion. Is there something
"special" one needs to do in php ?
here's the code snippet:
function parsehtmlline($line)
{
if (strlen(strstr($line, "#include")) == 0 &&
strlen(strstr($line, "<!--")) == 0) {
/* nothing to parse just print it */
print($line);
}
else {
/* extract the filename */
$ssi = extractHTMLssi($line);
/* open the file if it exists and output */
/* it else just print the string */
if (file_exists($ssi)) {
$incfile = fopen($ssi, "r");
while (!feof($incfile)) {
$ssiline = fgets($incfile, 1024);
// somehow PhP doesn't really like recursion, needs to be fixed
// for now just print the line.
// parsehtmlline($ssiline);
print($ssiline);
}
fclose($incfile);
}
else
print($ssi);
}
}
function extractHTMLssi($line)
{
$ssi = "";
$strptr = strstr($line, "\"");
if (strlen($strptr) == 0)
return $line;
else
{
$ssi=$strptr;
$iss=strrev($ssi);
$strptr = strstr($iss, "\"");
$iss = substr($strptr, 1, -1);
$ssi = strrev($iss);
}
return $ssi;

Absolutely. Why are you parsing it yourself anyway - what value are you
adding?

This is exactly where the problem lies. Apache isn't serving the page
to PHP. PHP is just reading the file from the filesystem. What you
might try is having PHP fopen() the url to the server/file. This way,
apache will parse the SSI and spit out what it needs, then you can read
the file anyway you like.
understand that php reading a file from the file system, is different
then your browser calling to a server/webpage and having Apache serve
the page back to the browser.

Recursive functions work just fine in PHP. What's the error message?
As far as I can see, there's nothing wrong with what you've posted, except for
where there's some inefficiency due to not having found the right functions to
use (see corrections below).

I'd replace the whole of this function body with something like:
$pos = strpos($line, '"');
if ($strpos===FALSE):
return $line;
else:
return substr($line, $pos+1, strrpos($line, '"')-1);
endif;

It's hard to tell very precisely just from what you've said, but here
are some general things you can check.
1) If magic_quotes are on for your server, the value you read from the
POST will already be escaped so using addslashes() would be redundant.
2) In any event, you'll find plenty of posts around here explaining
why you should use mysql_escape_string() instead of addslashes().
Note, if #1 above is a problem, you will want to unescape the string
with stripslashes() before you pass it into mysql_escape_string().
3) It's quite possible your makeLinks() function is not quite right.
I've found that given the allowable characters in a complete URL it
can be pretty challenging to get a function to find and convert all
the URLs in a string without converting too many or too few. Your
problem sounds like this sort. After it has converted the full URL to
a link, the pattern then finds the domain name as a URL within the
HREF attribute of your anchor (A) tag and then converts THAT to a link
so that the HTML ends up looking something like this (with angle
brackets substituted for the square ones below:
[a
href="http://www.abc.com/"]subfolder/folder2/"]http://www.abc.com/subfolder/folder2/[/a]
4) If you needed to use stripslashes() on the value that you read from
the database you should probably do that before you pass the value to
makeLink(). However, if you've dealt successfully with #1 and #2 above
I doubt stripslashes() is necessary. Using addslashes() or
mysql_escape_string() does not mean the value is stored with the extra
escape characters, so there are no extra characters to remove when you
select it from the database.

In my tests, Python can parse both Adler-32 and CRC32, while PHP can
only do Adler-32.
Anyways, I shortened my function:
function fixAdler32($data) {
static $f;
if (!isset($f)) $f = tempnam('/tmp', 'gz_fix');
file_put_contents($f, "\x1f\x8b\x08\x00\x00\x00\x00\x00" .
$data);
return file_get_contents('compress.zlib://' . $f);
}

For convenience let's label the cases:
1: if( isset( $myArray[$key] ))
2: if( array key exists( $key, $myArray ))
3: if( $myArray[$key] )
Now, surely 3 is not comparable at all to 1 and 2.
Cases 1 and 2 check that the key exists in the array.
Case 3 does a boolean test on the value referenced by the key. That has several
consequences:
Firstly, if there is no element with key "$key" in the arrray, the interpreter
will throw an error (undefined index ...); this error could be suppressed and
ignored, I suppose.
Secondly, if the value referenced by the key is equivalent to FALSE, then the
test will return FALSE; for example, if you have set $myArray[$key]='' or
$myArray[$key]=0. This could be very confusing.
So if you want to test that the key exists, case 3 is NOT the way to do it. In
fact, you will often want to check that the key exists(with case 1, ideally)
BEFORE using a test of the form of case 3.
