chris...
i'll humour you.. although i'm pretty sure you have no idea as to
what i'm trying to acomplish.. or how to get to my goal...
the basic issue is to allow a user to click inside an image map, and
to translate the coordinates to something else, prior to sending the
information back to the server..
Ooohh...
the solution to this appears to need to be a combination of
jscript/php... thus the posting...
Actually it doesn't appear to be a mixture at all... It is solely the...
responsibility of javascript (or another client... side technology) to
do the transmalating... you speak of. PHP is completely... out... of
the... loop. ...
[snip/]
so i waste another 30 secs dealing with some clueless person...
Come back when... you have a PHP question... and we can chat...

A PHP solution to your problem is to save the x y co-ordinates in a
session and do a refresh, then get the values fom session.
Do something like
?php
session_start();
if(isset($_SESSION['x']) isset($_SESSION['y'])){
//do your thing here
unset($_SESSION['x'];
unset($_SESSION['y'];
}else{
//get x and y from request variables here
if($x $y){
$_SESSION['x'] = $x;
$_SESSION['y'] = $y;
header('location: '.$_SERVER['PHP_SELF']);
exit;
}else{
//show start page
}
}

Excelent! The Content-length did it. The only thing I don't understand is that

[PHP] SFTP problems
I need to use SFTP to send text files and binary files from one server to another, but I'm unable to use fopen on the remote server, and if I send with ssh2_scp_send the files are truncated. I'm assuming the libssh2-PECL/ssh2 installation isn't the problem because I'm able to connect using ssh2_auth_password, create a directory on the remote server with ssh2_sftp_mkdir, and copy files with ssh2_sftp_send and ssh2_sftp_recv (even though ssh2_sftp_send truncates files). When I try to use fopen, I get this error message: Warning: fopen(): Unable to open ssh2.sftp://Resource id #10/whatever.com:22/home/whatever/public_html/flamingo/test.txt on remote host in /home/user/public_html/cms/sftp_test.php on line 79 Warning: fopen(ssh2.sftp://Resource id #10/whatever.com:22/home/whatever/public_html/flamingo/test.txt): failed to open stream: Resource temporarily unavailable in /home/user/public_html/cms/sftp_test.php on line 79 Here's line 79 of sftp_test.php: $stream = fopen(ssh2.sftp://$sftp/whatever.com:22/home/whatever/public_html/ flamingo/.$filename, wt) I've read Secure Communications with PHP and SSH in the February PHP Architect.

[PHP] asterix for arrray_search?
Hi there,
I am trying to find out how to match a search on : 5a or 5b with array search.
Basicly I would like to make it true as soon as the function finds a value
starting with 5.
As for now I have:
if (array_search('5a', $emsg) OR array_search('5b', $emsg)){
...
that statement will get very long till z :-)
Any ideas how to make something like this:
array_search('5*', $emsg)
Thank you for any hint,

Re: [PHP] Re: rename
Hi, That's what I've done, but I does not say clearly _when_ @rename should failed. I've read the documentation in the C library for Unix, and it says that it failed when it can't _add_ an entry to the directory. What I observe is an empty file... still weird, I'll look depper into it. (since i've been bitten by it with my website being 'blank page' since it grew out of space...)

I believe that in recent versions of PHP, the preg_* functions will accept
an array as an argument... Or maybe I dreamed that.
You should benchmark the solutions and also consider just using implode()
on the array to make a giant string and search that.
Depending on a lot of factors, any of these could out-perform the others.
Try it with data as close to real-world as you can get.

Sure.
Change your LINK to a FORM with an INPUT TYPE=image and use
METHOD=POST on the FORM tag.
form method=postinput type=image name=clicked
src=images/clicker.jpg/form
?php
if (isset($clicked_x)){
echo ($clicked_x, $clicked_y)br /;
}
?
I dunno why everybody else gave you such complicated answers.
It's still not a PHP question, though, except it's confusing PHP changes
.x and .y into _x and _y on the variable names because . is not
valid in variable names. :-)
There, that made this post on-topic. Sort of.

If that fails, I guess you could try: ?php ob_start(); phpinfo(); $phpinfo = ob_endclean(); ? Then you have to dig out the PHP User from that. It's possible there is a PHP Constant here that is the User: http://php.net/manual/en/language.constants.predefined.php If none of those work, I'm guessing even Windoze has something like whoami so you could http://php.net/exec whoami or its equivalent, based on the http://php.net/php_sapi_name If all that fails, I'd just give up. :-) -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: Using Exec Function

Can I run a program (exe file) in another way ? If you've got the Hello.exe running, but not returning, you could *MAYBE* do : ?php exec(Hello.exe , $output, $error);? The will put it into the background, even in Windoze, I think... If not, figure out how Windows starts background tasks, and do that. Or make Hello.exe actually be a tiny little program that forks off the program you really want to use, and then returns. Or... Lots of ways to try to force the OS to fork the process. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

is it possible to compare two different text messages and highlight

i mean to say that
$text1=message 1
$text2=message 2
i want to compare both $text1 and $text2 for differences and highlight
the differece in php.is it possible.
waiting for your reply.
Untested, very crude:
?php
$maxlen = max(strlen($text1), strlen($text2));
for ($i = 0; $i $maxlen; $i++){
if (@$text1[$i] == @$text2[$i]) echo @$text1[$i];
else @echo font color=red$text1[$i]|$text2[$i]/font;
}
?

Would it be possible to explode both messages oninto an array and
run array_diff() and work from there?
Just a thought late in the day...
