Also, I went over php.ini with ExamDiff to make sure I wouldn't miss any changes; the extensions directory is properly set. Otherwise consult the updated install.txt for more information As I said, the installation instructions haven't changed much. Mostly, it seems that PHP5 was simply substituted for PHP4 in the text.

[PHP] Problems with PHP5 RC1
I'm writing this message in the hope that some of the people responsible for PHP5 will eventually read it. I have just downloaded and installed PHP5 RC1 according to the instructions found in the package (which are basically the same as for previous releases of PHP). Before relating the problems I've had, I should say that I've been using PHP for about four years now and have successfully performed dozens of installations, under Windows, Linux and FreeBSD, so I'm not exactly a newbie having a go at his first install. I'm trying to run PHP5 RC1 on a Windows 2000 test server with Apache 2.0.47. Upon installation, when I first started Apache again, I got an error message to the effect that php4ts.dll could not be found in the c:\winnt\system32 directory. This is curious for two reasons: first and foremost, if anything is missing, it should be php5ts.dll, not php4ts.dll; second, php4ts.dll never used to be in the system32 directory and that never caused any problems. But it's no use cursing PHP5, so I copied php4ts.dll to the system32 directory and stopped getting the error message. Not a pretty solution, though. I then edited php.ini to load the extensions I need, and noticed that the php_domxml extension is no longer an option, so I assumed that DOM XML is now bundled with PHP. As a matter of course, phpinfo() tells me that DOM/XML is enabled and that the libxml version is 2.5.11. However, when trying to use domxml_version(), domxml_new_doc(), domxml_open_mem() or any other DOM XML function, I get a call to undefined function error. If these functions now have new names, they're not listed in the online documentation. Am I doing something seriously wrong or are these problems with PHP5 RC1? Thanks, Erik
[PHP] Regular expression checker
Hello all,
For a while I tried in vain to find a decent regular expression tester. The closest I
found
was RegExpEditor, by the same people who produce PHPEdit, but I found it to be slow
and didn't like its constant bitching about invalid delimiters or some such thing.
Anyway, I ended up writing a little tester for Perl-compatible regular expressions and
thought I'd share it with you. Maybe it'll come in handy to people who often need to
use
regular expressions in their projects. Just copy the code below the dotted line (which
has Unix line breaks) and save it to a file.
Cheers,
Erik

[PHP] Re: PHP Sessions - One Server, Many Terminals
Damon, Sessions have to do with requests being sent by browsers to the web server. Each time you close all the windows of your browser on your computer and start the browser again, a new session is started. I suspect that since all your users are essentially using the same web browser (since their monitors and keyboards are not really separate computers, but peripherals on the same machine), a browser window open on one terminal is keeping alive a session started by another user on another terminal when she or he first started the browser. Does that make sense? Anyway, if that's your case, then I don't believe there's anything that can be done. Erik On 16 Mar 2004 at 13:04, Damon Abilock wrote: I'm having a problem related to PHP sessions in a school computer lab environment. I have a script that uses sessions to keep track of a user and their work on the system. It is being used by a school in a computer lab in which the students just have terminals -- they all access the same server computer to run programs and do not have hard drives of their own. They are running software called ClassLink (see www.classlink2000.com) in this lab (I'm not sure if that is really an important detail or not). The problem is that everyone that students accessing the script on these different terminals start seeing eachother's work, which implies that the session information is not unique to each terminal (I expect that if I printed out the session ID on all of these different terminals, they would all be the same). Is there anything that I can do about this?

I'm having trouble understanding how your application works. For starters, I don't see
where $POST['sellocation'] is being set, because you didn't provide us with that part
of
the code. It's true that, as it didn't make immediate sense to me, I didn't bother
reading
the code again because I don't have much time.
A couple of things off the top of my head that may or may not be related to your
problem: (a) if you're using any values sent via the URL string (e.g. cf=0), you need
to
use $_GET, not $_POST; (b) empty() will also evaluate to true if the value of the
variable
is zero.
Good luck,

You're trying to organize your files so that each set is only accessed via one protocol (http or https), which makes pretty good sense from an administrative point of view. On the other hand, you're not necessarily *required* to do that: unless your web server somehow directs all https traffic to a separate branch of your web directory structure, users can access any file on the server via either http or https (provided, of course, that your web server is properly configured). What this means is that you can have a user access a certain page via https by simply providing a link containing https://; as the prefix. The down side of this solution is that users will be free to *not* use https by typing the path to the page directly into the browser without the https://; prefix.

Isn't that what most of the big web sites do? It should be possible to use CSS/(X)HTML to present your content in a way that is accessible to whichever browser accesses your site. IMHO, browser-sniffing to serve different content is a bad idea. What about obsolete browsers that don't handle CSS too well (or not at all)?

You're joking, right? Your second header statement is outside the if/else loop, so

Don't spend your money on Professional PHP4 (Argerich, Choi, Coggeshall, Egervari, Geisler, Greant, Hill, Hubbard, Moore, O'Dell, Parise, Rawat, Sani, Scollo, Thomas Ullman): it's mostly badly written and the really relevant stuff is not clearly explained; you get the feeling (probably pretty accurate) that the book was banged out by a bunch of programmers who cannot write good English and have no experience teaching or explaining things to others or even building a logical argument, for that matter. Don't go near XML and PHP (Vaswani), either. Also badly written and already outdated. In addition, the book doesn't give you any information that you could not easily find on the web. If you already know the basics about manipulating XML with PHP, you won't learn anything new from this book, either. I recently bought Secure PHP Development (Kabir) and it seems to be interesting, but I haven't yet found the time to get past the introduction and a first browse, so I can't really recommend it.

[PHP] Re: file downloads using header problem
Hello Joshua, On 9 Feb 2004 at 15:45, Joshua Minnie wrote: Does anybody have any idea to allow for multiple downloads while another one was going on. Maybe some additional headers? I have tried adding headers before and after where I open the file for HTTP/1.1 200 OK and the corresponding headers. I have also tried using a simple meta refresh, but that doesn't work because it won't refresh until the page is entirely loaded. I am at a loss, I can't seem to find answer when I google it either. Maybe I'm just missing something. I don't know. The same script can only send headers to the browser once each time it's loaded. In other words, after a script has been parsed and the page has been loaded, it cannot send more headers to the browser unless you reload it. Since in your case the same script (i.e. same page) does everything, it can only handle one download at a time; that's basically what I think you're missing. A simple solution is to have each download link call a *separate* script (i.e. another page) whose sole purpose is to take care of generating the download, i.e. sending the headers and the file to the user's browser. Think about how ZDNet or Tucows, for example, work: first you choose the file you want to download from a menu (the main download page, which doesn't actually generate the downloads), and then when you click on the download link you're taken to a new page (the one that actually takes care of the download) that tells you to wait a few seconds until the download starts. If you're concerned about security (i.e. unauthorized users downloading files by accessing the actual download script directly without going through the page where they see the file list etc.), you can use some kind of random authorization code that is sent by the main download script via a GET string to the actual download page. That way, if the right authorization code is not received by the script on the page that generates the headers and sends the file to the browser, the download will fail. (Note that I suggested a GET string because you cannot normally start sessions before sending headers to the browser, as session_start() will itself send headers. But you can always play with output buffering if you like.) Hope this helps, Erik -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Just adding to Marek's response in an attempt to make things clearer for you. I think what's bothering you is the fact that you don't see the backslashes added by addslashes in the strings stored in the database. Well, that's because they are *not* actually added to the strings; they simply tell the database to treat whatever character comes after them (them = the backslashes) as regular text, not as symbols with special meanings (such as quotes, which MySQL would normally sees as string delimiters, not actual quotes in a string of text). Since no backslashes have actually been added to the strings stored in the database, you don't need to (or, rather, should not) use stripslashes when retrieving the strings from the db. By the way, consider using mysql_escape_string or mysql_real_escape_string instead of addslashes; consult the PHP manual for more info on these functions.

To keep question and id together even after shuffling the array, why don't you build
an
array of arrays like this:
$i = 0;
$questions = array();
while( $row = mssql_fetch_array($result) )
{
$questions[$i]['ques'] = $row['question'];
$questions[$i]['id'] = $row['id'];
$i++;

srand((float)microtime()*100);
You don't need to seed the random number generator if you're using PHP 4.2.0 or
above.
shuffle($ques);
(...)
What I'm wanting to do now is to add the id for each of the questions so
that I can track which one is the correct answer and which are the
distractors. I will have something that looks like this.
Foreach($ques as $ranQues){
echo trtda href=\$id\$ranQues/a/td/tr\n;
}
My problem is keeping the $id with the $ranQues after I do the shuffle.
That's not a problem if you follow my previous suggestion. All you need to do is:
foreach($questions as $ranQues)
{
echo trtda href=\$ranQues['id']\$ranQues['ques']/a/td/tr\n;

Hi John, On 26 Jan 2004 at 21:42, John wrote: How can I show xml files which have been created in MS Word, in a browser as ie Html. Is this posible and what would it take. The short answer to your question is Yes, it's possible. As for what it would take, the answer is a little longer. First of all, you need to decide whether or not you'll expect your target audience to have latest-generation browsers (Netscape 7.x, IE 6, Mozilla 1.4 etc). If you go with the latest-generation-browser-only alternative, all you need is a suitable XSLT stylesheet attached to your XML file; to attach a stylesheet to an XML file you simply open it (manually or with PHP), insert a suitable processing instruction and re-save the file. For more information on XSLT, start here: http://www.dpawson.co.uk/xsl/sect1/intro.html . If you opt for the old-browsers-welcome alternative, PHP will come in really handy. You'll still need an XSLT stylesheet to transform your XML files and output whatever you like, but as most old (and not so old) browsers do not have a built-in XSLT processor (aka engine), you'll *also* need an external XSLT processor, a role that PHP can fill very well. Look up XSLT functions in the PHP manual (chapter CXIII in the function reference section) for more information on utilizing PHP as an XSLT processing engine. Either way, you'll need to learn some XSLT; how much will depend on your needs. Good luck, Erik

I found out another very curious thing about both AddSlashes() and

meaning. Someone told me it might be the beginning of a comment line in the SQL
statement. In any case, there is only ONE #-char inserted into the database, instead
of
two. The two escape functions DO NOT escape this two-char-sequence. So if you want
to insert an image in the database and be SURE the image is not f#ck#d up, then do
the escaping yourself:
$filedata = str_replace('##', '\#\#', mysql_escape_string($filedata));
$query = insert into IMAGES (IMAGE) values ($filedata);
$result = mysql_query($query);
I hope this will save you guys the ours that I spent by searching for the bug in my

Re: [PHP] random html +(hi)
Hello Angela, On 16 Jan 2004 at 11:30, Angela K Hilton wrote: I'm trying to dynamically randomise a chunk of HTML that is used on a page, aka random image, so that each time a client opens the page [or refreshes] a part of the page changes. The chunks of HTML are saved in their own directory as .htm files. I was hoping to adapt the following code I have managed to cobble together to display random images: ?php // images in folder $total = 5; If the value of $total is not going to change, why even use a variable? // file type $file_type = .htm, .gif, .jpg; What's this $file_type for? // dir location $image_folder = dir/dir; $start = 1; Again, if the value of $start is not going to change, why use a variable? $random = mt_rand($start, $total); $image_name = $random . $file_type; This won't work. You'll end up with something like $image_name = 2.htm, .gif, .jpg;, which is clearly not what you want (or need). // print file name // echo $image_name; // display image // echo img src=\$image_folder/$image_name\ alt=\$image_name\ /; ? I'd like the code to take the HTML and place it in a div/div, probably using a ?php require (); ? (I think I'm OK with this once the code is sorted). Suggestion: have your PHP script open the image folder, read it's contents and load all file names it finds onto an array; then user array_rand() to randomly pick a key. You'll need to get the PHP manual (in case you still don't have it) from http://www.php.net/download-docs.php and read up on opendir(), readdir() and array_rand(). Good luck, Erik

[PHP] Re: Week calculating
A quick idea that can probably be perfected:
?php
function calc_weekday_dates ($weekday, $year)
{
$weekday_options = array('mon', 'tue', 'wed', 'thu', 'fri', 'sat', 'sun');
// Check argument $weekday
if( !in_array( strtolower($weekday), $weekday_options) )
{
return false;
}
// Check argument $year.
if( $year 1900 || $year 2050 )
{
return false;
}
$ini_date = mktime(0, 0, 0, 1, 1, $year); // Jan. 1
$end_date = mktime(0, 0, 0, 12, 31, $year); // Dec. 31
// The array to be returned.
$weekday_dates = array();
// There are 86400 seconds in a day.
for( $i = $ini_date; $i = $end_date; $i += 86400 )
{
if( strtolower( date('D', $i) ) == strtolower($weekday) )
{
// Format the wanted dates.
$weekday_dates[] = date('y-m-d', $i);
}
}
return $weekday_dates;
}
$test = calc_weekday_dates ('Tue', 2004);
print 'pre';
print_r($test);
print '/pre';
?
Seems to work. Now you can improve on it.

hello, i need to replace some words in file with [tag]word[/tag] and other

replacing those words is easy i just use preg_replace('/\b( ' . $words .

but how to replace all other words that are not in $words array with [tag]
tag ?
thx in advance!
Let me see if I understood you correctly: you want to surround all the words in the
string
$file that are not also contained in the $words array with [tag] and [/tag]?
Here's an idea:
?php
$file = 'this is my test string and I just want to use it for a quick test';
$words = 'test|string';
$new_file = preg_replace('/\b('.$words.')\b/', ' [sample]$1[/sample] ', $file);
$new_file = preg_replace('/\b(?!\[sample\]|\[)(\w+)(?!\[\/sample\]|\])\b/',
' [tag]$1[/tag] ', $new_file);
print $new_file;
?
Very important: you *must not* forget the spaces before and after the opening and
closing brackets in the replacement string.
Good luck,
Erik

Re: [PHP] How do I write to an XML file
Hello Tim, On 12 Jan 2004 at 17:50, Tim Burgan wrote: I'm wondering if anyone can help me or point me in the right direction regarding how I can write to an XML file. Writing to an XML file works the same way as writing to any other file: you need to open the file with fopen(), append to or overwrite the file contents with fwrite(), and close the file with fclose(). However, In order to do something useful with the XML in your files, you'll also want to read the file right after opening it (i.e. before writing anything to it), parse the XML, insert new elements/attributes/text nodes into the XML, and then write that to the file. The XML parsing and manipulating can be accomplished with the DOM XML functions (see chapter XXIV of the function reference section of the PHP manual) or the XML Parser (Expat) functions (see chapter CXI of the function reference section of the PHP manual). Both sets of functions are PHP extensions, which means they are not enabled by default; on *nix systems, you need to compile these extensions when installing PHP, and on Windows systems you need to enable the extensions in the php.ini file. Alternatively, if you cannot or don't want to install/reinstall PHP on the web server you're going to use, you can use PHP classes that emulate the DOM XML extension. The best ones I know of are miniXML (http://minixml.psychogenic.com) and Domit! (http://www.engageinteractive.com/domit/); both are free and come with fairly good documentation that will explain how to use them. There probably are a couple of classes out there to do Expat-style (chunk by chunk) parsing, but in your case you'll probably want to stick with DOM-style parsing. Good luck, Erik

Hi Philip, On 10 Jan 2004 at 12:42, Philip J. Newman wrote: I want to store some images outside the /public_html/ how ever my isp has decided that i'm not aloud to write files in that area. Would the next best solution that wold be as secure to maybe put them in a folder with a .htaccess file in it? You could use an htaccess file, but: (a) the Apache web server must be configured to allow htaccess to over-ride authentication settings (which, from what you've told us, is something you'll have no control over); (b) you'd need to upload an htpasswd file containing username and passwords pairs to the webserver, but wouldn't be able to save it to an off-web directory; and (c) the htaccess file would prevent your own scripts from accessing the image files, which would mean that the user viewing a page with a protected image would need to type a username and password in order for the image to be displayed. Doesn't sound like the best solution to me. Do you have access to a database? One solution would be to store all images on a database and have the image files generated dinamically via PHP. That would imply in some overhead, but it would be fairly secure. If you like the idea, let me know and I'll tell you how I've implemented it in the past. Another much more complicated solution would be to rename your image files with a PHP extension (thus protecting their contents) and create a script to read these files, extract their contents and create temporary PNG/JPG/GIF files on the fly.

Hmm, this has nothing to do with your question, but don't you need a concatenation

Why is if capitalized? Well, it doesn't affect the execution of the code, but it's
bad
practice. More importantly, why is the number 95 between quotes? You're comparing
numbers, not strings. Granted, PHP will convert the string into a number for you, but
that's bad practice again.
$lines = $dom $totalused $totalfree $total \n;
for( $i=0;$icount($lines);$i++) {
Aha! Count lines?! What lines do you want counted? $lines is a string, not an array,
so
how can you possibly count the number of array elements contained in $lines?
$message .=$lines[$i];
}
}
echo $message;
}
Perhaps what you really want is to create an array $lines with all the strings that
you
need and print them at the end. I'm not sure I understand your needs exactly, but
wouldn't something like the code below work better for you?
/*** CODE START ***/

I've just checked your online pages and your form is being sent to action.html, not action.php, so the PHP code is not being processed, because your web server doesn't look for PHP code in HTML files. I had a look at the source of your action.html file and it's like this: html Hi. Your name is ?php phpinfo(); echo $_POST[name]; ?. /html The phpinfo() function is going to print a long list of information about PHP on the server, so you might want to remove that. So, to recap, you need to change the action attribute in your index.html file to action.php, and then rename the file action.html to action.php (and maybe remove the phpinfo() function while you're at it).
