I don't know if the same syntax is available on Linux, but on Solaris
I can use the 'tail -f' command to watch lines being appended to a
file from the commandline.. You might be able to do something via
passthru("tail -f $PathToSyslog");
in a frame on your page...although there might be socket_blocking or
page flush() issues to experiment with -

I didn't make my last request very clear. I used lastlog as an example,
but what I really want to do is open a syslog file (text file), that is
coming in from a VPN box.
I'd like to have it displayed live so I can scan it during the day.
What is the best way to do this? Someone had suggested using cron, but
I'm very new to Linux and PHP so I would need some help with that.
Any help is appreciated,
Carlton.

I don't think you're doing anything wrong, except perhaps for using an outdated
browser.
The "ë" (e-umlaut, which you called a "dotted e") displays just fine in both IE 6 and
Netscape 7.1 on my computer.
Make sure your browser is configured to use Western European (ISO-8859-1) encoding,
because even latest-generation browsers have poor support for UTF-8. To change your
browser's encoding settings, do:
In IE 6: View > Encoding
In Netscape: View > Character Coding
Any other browser: figure it out yourself ;-)
Take care,
Erik

Good evening.
I'm trying to read using $_POST, 4 radio buttons named "miles". I tried
reading the selected value with $_POST['miles[0]'], etc. with no success.
I've even tried using foreach to read the selected radio button with no
success.
Help!! I'm totally stumped with this one. I thought the value was passed
back as an array but maybe I'm wrong...

You can't use variables inside single quotes, either.
This:
'/path/to/old.$today'
ought to be:
"/path/to/old.$today"

Here is a function that will do this, assuming $items is an array you would
do the following:
// $size INTEGER
// $width INTEGER
// border INTEGER
// $cpadding INTEGER
// $cspacing INTEGER
// $data ARRAY
function horizontalTable($size, $width, $border, $cpadding, $cspacing,
$data)
{
$table_width = $width;
$width = intval($table_width / $size);
$tr = '<TR ALIGN="left">';
$td = "<TD WIDTH=\"$width\">%s</TD>";
$table = "<TABLE WIDTH=\"$table_width\" BORDER=\"$border\"
CELLPADDING=\"$cpadding\" CELLSPACING=\"$cspacing\">" . $tr;
$i = 0;
foreach($data as $value)
{
$table .= sprintf($td, $value);
$i++;
if(!($i % $size)) {
$table .= '</TR>' . $tr;
}
}
while($i % $size)
{

$i++;

Here is a function I use. Assuming data is stored in an array called $items
you will call out horizontalTable() like this:
horizontalTable(3,600,1,3,3, $items);
Here is the horizontalTable() function code:
// $size: number of columns
// $width: table width
// $border: table border
// $cpadding: table cellpadding
// $cspacing: table cellspacing
// $data: array with data you want to display
function horizontalTable($size, $width, $border, $cpadding, $cspacing,
$data)
{
$table_width = $width;
$width = intval($table_width / $size);
$tr = '<TR ALIGN="left">';
$td = "<TD WIDTH=\"$width\">%s</TD>";
$table = "<TABLE WIDTH=\"$table_width\" BORDER=\"$border\"
CELLPADDING=\"$cpadding\" CELLSPACING=\"$cspacing\">" . $tr;
$i = 0;
foreach($data as $value)
{
$table .= sprintf($td, $value);
$i++;
if(!($i % $size)) {
$table .= '</TR>' . $tr;
}
}
while($i % $size)
{
$table .= sprintf($td, ' ');
$i++;
}
$end_tr = strlen($tr) * -1;
if(substr($table, $end_tr) != $tr){
$table .= '</TR>';
} else {
$table = substr($table, 0, $end_tr);
}
$table .= '</TABLE>';
return $table;
}

Warning: mysql_connect(): Too many connections at
/home/local/global/php/libraries/dblayer_mysql.php line 14.
The connections are already limited, that's why you get this warning.
You need to handle this from the MySQL side and increase the number of
connections allowed either when you start MySQL or in a config file.
Directions are in the manual, of course. :)

=======================================
This message is for the benefit of new subscribers
and those new to PHP. Please feel free to add
more points and send to the list.
=======================================
1. If you have any queries/problems about PHP try
http://www.php.net/manual/en first. You can
download a copy and use it offline also.
Please also try http://www.php.net/manual/faq.php
to get answers to frequently answered questions
about PHP (added by Christophe Chisogne).
2. Try http://www.google.com next. Searching for
"php YOUR QUERY" may fetch you relevant results
within the first 10 results, if you are lucky.
3. There is a searchable archive of the mailing
list discussion at
http://phparch.com/mailinglists. Many of the
common topics are discussed repeatedly, and you
may get answer to your query from the earlier
discussions.
For example: One of the repeatedly discussed
question in the list is "Best PHP editor".
Everyone has his/her favourite editor.
You can get all the opinions by going through the
list archives. If you want a chosen list try this
link : http://phpeditors.linuxbackup.co.uk/
(contributed by Christophe Chisogne).
4. Not sure if PHP is working or you want find out
what extensions are available to you?
Just put the following code into a file with a
.php extension and access it through your
webserver:
<?php
phpinfo();
?>
If PHP is installed you will see a page with a lot
of information on it. If PHP is not installed (or
not working correctly) your browser will try
to download the file.
(contributed by Teren and reworded by Chris W
Parker)
5. If you are stuck with a script and do not
understand what is wrong, instead
of posting the whole script, try doing some
research yourself. One useful trick is to print
the variable/sql query using print or echo
command and check whether you get what you
expected.
After diagnosing the problem, send the details of
your efforts (following steps 1, 2 & 3) and ask
for help.
6. PHP is a server side scripting language.
Whatever processing PHP does takes
place BEFORE the output reaches the client.
Therefore, it is not possible to access the
users' computer related information (OS, screen
size etc) using PHP. You need to go for
JavaScript and ask the question in a JavaScript
list.
On the other hand you can access the information
that is SENT by the user's browser when a client
requests a page from your server. You can
find details about browser, OS etc as reported by
this request. - contributed by Wouter van Vliet
and reworded by Chris W Parker.
7. Provide a clear descriptive subject line. Avoid
general subjects like "Help!!", "A Question" etc.
Especially avoid blank subjects.
8. When you want to start a new topic, open a new
mail composer and enter the mailing list address
[EMAIL PROTECTED] instead of replying to
an existing thread and replacing the subject and
body with your message.
9. It's always a good idea to post back to the
list once you've solved your problem. People
usually add [SOLVED] to the subject line of their
email when posting solutions. By posting your
solution you're helping the next person with the
same question. [contribued by Chris W Parker]
10. Ask smart questions
http://catb.org/~esr/faqs/smart-questions.html

Hope you have a good time programming with PHP.

Hi,
I'm using debian-unstable.
I just installed apache-1.3 and php4.
I don't know where else to ask. I made a php test file (phpinfo.php),
containing: <? phpinfo(); ?>, and put it in ~/public_html.
When i try to see it by putting: http://127.0.0.1/phpinfo.php into
mozilla 1.2.1, mozilla changes it to http://211.27.78.162/.
Is this a mozilla config problem or apache problem? I have my dialup isp

After moving my PHP files to a new hard drive and a new windows
installation, my rand function gets stuck and only gives you one number over
and over. It worked a few times then got stuck. I tried using IIS 5.1 (I
was using Xitami) and it gave me the same results. It even gets stuck on
the same number as the other webserver. I tried installing on a different
machine. Same result. Can anyone help?
Thanks

Which version of PHP are you using? If it's earlier than 4.2.0 you
need to see the rand() function first, or it will return the same
numbers each time. Use srand() to do this.
Also, are you passing in values to the rand() function? (your min and
max values) - on Windows there is a limit on the max value of 32,768.
