Use system() and background it with &:
$cmd = "tail -f /var/log/messages &";
system($cmd);

I had a hard time interpreting your question, but I think you're saying
that you are generating URLs like this:
/page.php?foo1=bar1&foo2=bar2&foo1=bar3&foo2=bar4
And, you're wanting to not duplicate variables in your URL, correct?
You could always keep your query string in an array or something. This
would allow you to update values in the array prior to the end of your
script. You can start this array using $_GET:
$query = $_GET;
Of course, you might want to rather filter this data on each page, so that
you don't spread tainted data more than necessary. Regardless, this will
allow you to update values in your query string. If you want to update
foo1, you don't have to care whether it's already set:
$query['foo1'] = 'newvalue';
Hope that helps.

Sorry for the confusing initial request.
You were correct in assuming that I am generating URLs like:
page.php?foo1=bar1&foo2=bar2&foo1=bar3&foo2=bar4
So I suppose the consise follow-up question is how can I get a hyperlink to
change one of those varibles in the string.
In the past I have just tacked a varible on to the end of the string, but I
don't want to be redundant.
Thanks again.

To make this easy, I really think you need to not use a string like you
keep suggesting and use some other data structure. I mentioned an array,
simply because I think one of PHP's strengths is its rich collection of
array functions.
You can build your query string as the very last step, prior to using it
in a link. While you are constructing it, I think you will find using a
string to be about the most cumbersome approach possible.
Hope that helps.

Do I use ldap_search to authenticate users in LDAP?
I can successfully search the LDAP and retrieve user's data based on a
search criteria like (cn=something).
If I use (password=somepass) or (userPassword=somepass) in the search
criteria it comes back with no hits.
How should this be done? Do I have to encrypt the password somehow?
Thank you!

Hi all:
The money_format function does not do it for me. Is
there a simple php function which appends the '$'
symbol to a string value. Example
$money = 30
$money = some_php_function($money)
echo $money
//should show $30
thanks

Hmmm, that's prepending... how about:
$money = 30.'$';
or if he wants it at the beginning:
$money = strrev( strrev( '30' ).'$' );
*heheh*

Hello, sorry this mysql question here, but I cant't answer this one.
I have database with BLOB fields to hold pictures (60-90 kb each).
Actually I am erasing these BLOB fields (move '' into and update rcord)
to free some space from my DB, but space is not released by mysql. I
verified BLOB fields really were erased.
How can I tell mysql recover these space?
Thanks
Miguel

Dear Jason,
I try your advise which is imap open sample like follows and I get;
Warning: imap_open(): Couldn't open stream {mail.smsavantaj.com:110/pop3
$mbox = imap_open ("{mail.test.com:110}", "[EMAIL PROTECTED]", "1234");
echo "<p><h1>Mailboxes</h1>\n";
$folders = imap_listmailbox ($mbox, "{mail.smsavantaj.com:110}", "*");
if ($folders == false) {
echo "Call failed<br>\n";
} else {
while (list ($key, $val) = each ($folders)) {
echo $val."<br>\n";
}
}
echo "<p><h1>Headers in INBOX</h1>\n";
$headers = imap_headers ($mbox);
if ($headers == false) {
echo "Call failed<br>\n";
} else {
while (list ($key,$val) = each ($headers)) {
echo $val."<br>\n";
}
}
imap_close($mbox);

Find out what funky thing it was that you did to make it stop working.
Are you using safe mode and is "safe_mode_exec_dir" set appropriately?

Hi all,
is there a way to tell at runtime if PHP is running as an Apache module or
through CGI?
phpinfo() shows this piece of information ("Server API" on the first page).
But is it available as a server variable or a constant or whatever?
I want to know this because I want to set the HTTP status code for a PHP
script, and AFAICT this has to be done differently, depending on the server
API:
header("HTTP/1.1 304 Not modified"); for the Apache module
header("Status: 304 Not modified"); for the CGI interface
If this can be done with the same PHP code on both server APIs, that would
solve my problem too.
Thanks in advance,
Richard

Greetings all,
I'm looking for a tutorial or some assistance in explaning how store and
then open and read a binary file using php/mysql.
I've got a few tutorials about storing the binary data _within_ a mysql
table from Kevin Yank, phpbuilder, etc. but I've heard that it's sometime
better to keep your binaries on the server and not in the database.
Thus, if the developer just keeps the file path in a VARCHAR column like:
C:\apache\images\house.jpg
C:\apache\images\tree.jpg
etc...
and then directs that file be
fopen()
fread(), etc.
it will work without the added overhead.
I'm a bit lost in what happens after the filepaths are inserted into the
database and what steps follow in the script so that they can be opened and
read.
Any help, URL's or tutorials will be of assistance.
Thank you.

Hi,
In the ini-files for my php-projects, I store various settings. Two of
them is username and password for my mysql-connections.
Is it safe to load these two into session variables when a user logs in
to my application? Or is it better to access the ini-file each time a
mysql-connection is needed?
What I don't understand, and hence the questions, is wether session
variables are accessible by my website's visitors, or just to the
php-scripts on the server.
