This ought to do it.  Try it and see.

But be aware that if the "allow_url_fopen" was not enable at the compile
time, this won't work.

This works: "District of St. Francis"

http://www.glquebec.org/tezt.php#District+of+St.+Francis
<a name="District+of+St.+Francis"></a>

This does not: "Montréal District #2"

http://www.glquebec.org/tezt.php#Montr%E9al+District+%232
<a name="Montr%E9al+District+%232"></a>
I'm beginning to see the problem lies with the French character "é". I don't see it being #. In any case, I cannot change existing fields. How can I get this working?

I'm not sure, but I see two things that might be causing this. First, why are spaces, which should be translated as %20, being represented as a '+'?
Second, you have a # in the actual bookmark name, which I would assume is not valid since the # denotes the beginning of a bookmark. So perhaps IE compensates for this, but Mozilla reads the bookmark as looking for <a name="4"></a> because of the #4 at the end of the bookmark name. 

I generate the link using urlencode.

   if ("" != $mydata->district){
echo " - <a href=\"#".urlencode($mydata->district)."\">$mydata->district</a></h1>"; 
   }else{
   echo "</h1>";
   }

The link is named:
echo "<hr size=1><a name=\"".urlencode($mydata->district)."\"></a><h2>$mydata->district</h2>\n";

AIUI, UTF-8 is a super-set of ASCII.

So if your filenames are all ASCII, you're fine.

If you've been using funky characters like umlauts and they've been
magically working, you could be in trouble...

At least, that's my best guess.

On one of the servers the information pulled from the data show degree symbols or greek lettering, which are supposed to be there. On the other server the places where these symbols are supposed to appear shows blank spaces. One server is RHEL3 the other RHEL4. I am not that familiar with charsets and how they interact with apache and php. I'd appreciate any help in trying to figure out where this problem is or what I should be looking for.

you can use strtotime to convert it to unix timestamp to compare...something like this: 

$stamp = strtotime('2004-06-31'); // $mydata->lastinsalled

if($stamp >= strtotime('1 year ago'))
{
   echo 'less than 1 year';
}
else
{
   echo 'over 1 year';
}
otherwise its impossible to tell if it is over one year without knowing the day as well.. unless you guess and figure on the first of the month..

Hello all, Ive been working with PHP for my websites for a few months, just attempted to build my own class, after reading all this stuff about automated robots and XSS attacks etc decided to step up security a bit, my result is an attempt to create a class for using the token method within web forms, not even sure whether its the real thing but my work is below, some advice on whether its ok or what needs improving would be appreciated, thanks. 


<?php
// PHP 4.3.11


class SecretToken {

    var $_returnCode;


    function GenerateToken() {
     if(!isset($_SESSION['token'])) {
      session_regenerate_id();


I wonder if regenerating the session id here is useful.
I understand doing it on log off/on but whats the connection
with creating a 'submit token'?


      $new_token = md5(uniqid(rand(), true));
      $_SESSION['token'] = $new_token;
     }
    }


    function VerifyToken($post) {
     if(isset($_SESSION['token'])) {
      $saved_token = ($_SESSION['token']);
     }


I think you should be unsetting $_SESSION['token']
round about here in order to make sure that each
submit a user does requires a different/new token.

I am assuming you have implemented this class in order
to trap double submits (as well as increasing the
security of you submits somewhat).

at the moment the user gets a single token for
ALL submits he does within a given session.




     if($post == $saved_token):
      $this->_returnCode = 1;
      unset($_SESSION['token']);
     else:
      $this->_returnCode = 0;
     endif;
    }


    function ReturnCode() {
## Result will be 1 for success or 0 for fail
      return $this->_returnCode;
    }



you can probably drop the ReturnCode() function
and just have the 1/0 returned directly from VerifyToken() e.g:

if (SecretToken::VerifyToken( $myTok )) {
        // lets do a submit
} else {
        // evil hacker, set the dogs on him.
}



// end class definition
}
?>
Basically in my web form I call GenerateToken firstly, then when the forms been submitted I then call VerifyToken and finally check return codes using a switch statement, seems to work, 

sounds fine to me.
rgds,
jochem

I took this example from php.net, but can't figure out where I went
wrong. Why does this:
$text = preg_replace("/<head(.|\s)*?>(.|\s)*?<\/head>/i" , "" , $text);

throw this error:
syntax error at line 265, column 39:
                $text = preg_replace("/<head(.|\s)*?>(.|\s)*?<\/head>/i" , "" , 
$text);
======================================^

It seems to be pointing to the 'e' is 'head'. Why? Thanks.

--- Begin Message --- Is there any way to perform an unbuffered read in PHP when reading from STDIN? 

I.E. if I have the code

---------------------
$chr = "";
while(!feof(STDIN))

 if($chr == " ")
   break;

and enter the following string (note this is how you would enter the string in a program to have it have the same value I'd type in): 
"this is a test\n"

It will stop reading at the newline, and not the first space.

Any ideas?

The simplest way to make sure everything work well regardless of what the values are: 

<?
$url = "somepage.php?var1=".urlencode($var1)."&var2=".urlencode($var2);
echo "<a href=\"".htmlspecialchars($url)."\">";
?>
htmlspecialchars() changes characters '&', '"', ''', '<', '>' into the HTML equivilant. And yup, you should do this for all *ML pages as long as the thing being printed is not part of the mark-up syntax.

I think you have the idea. The &'s are used to seperate the various
variables. If you want to set $p to something like 'Tom & Jerry' then
personally I'd do something like:

<?php

$p = "Tom & Jerry";
$s = "Cat & Mouse";
printf("<a href='{$_SERVER['PHP_SELF']}?p=%s&s=%s", urlencode($p),
urlencode($s));

?>


That's nice. To get more specific (because my code varies a bit from
yours and I don't wanna mess up the ) and ' and " s:
$p and $c are actually row ID numbers so up to 3 digits. So for example if 

$p=1
$c=32

I was wanting to see a URL of

http://foo.com?r=1&c=32



In that case, you can simply echo them out, once you're sure that $r,
and $c are actually integers.



I forgot to mention that above I did $r = intval($_GET[r])

!



Thanks, everyone!


echo "<a href='http://foo.com?r=$r&c=$c'>whatever</a>"

if not(sure they're integers, you could always
printf("<a href=\"http://foo.com?r=%d&c=%d\";>whatever</a>", $r, $c);

Alternatively you could $r = (int)$r;

or echo "<a href='http://foo.com?r="; . (int)$r . "&c=" . (int)$c .
"'>whatever</a>";

There's more than one way to do it.......


so was this the way to go?


    //Make a thumbnail table of contents to display in the left sidebar

    while ($sidebar = mysql_fetch_assoc($sidebar_result)) {
           $sidebar_thumbnails[] = "<a class='img-link'
href='{$_SERVER['PHP_SELF']}?p=%p&c={$sidebar['art_id']}, urlencode($p)' 
title=\"{$sidebar['art_title']}\"><img class='sidebar-img'
src='{$image_dir}{$sidebar['art_thumbnail']}' width='50' height='60'
border='0' alt=\"{$sidebar['art_title']}\" /></a>";
  }

?

Thanks in advance!

Hi,
If I want to make a link to a URL which includes some GETs can I just do: 

<a href='{$_SERVER['PHP_SELF']}?p={$p}&c={$s}' ... etc etc

or must I escape the ampersand somehow?
