That's not what Alice asked for though. She did mention that a remote
call would be made somewhere, but her question was:

And that works just fine using exec().

Hi, Todd:
It looks like I have some other errors in my Perl code, and I got it fixed,
switched the permission to 755, and made attempts to call it using cURL through
my working PHP script.
Here is the code:
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://192.168.10.63/total.cgi";);
curl_setopt($ch, CURLOPT_HEADER, false);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
This time, I do not get the "script" output from the script in total.cgi, but I
got
Forbidden
You don't have permission to access /total.cgi on this server.
I have switched the permission to both scripts at both servers. Is there
something wrong I have done here?
Thanks again for your help.
Alice

Alice,
If it's returning the code instead of the processed content, then it
means that the webserver which houses the Perl script is not
executing/parsing it. You should check with the administrator of the
remote webserver to see if they have a Perl module installed, and if it
is configured properly for your web app.
HTH,

Well... if she was trying to execute *LOCAL* PHP code from within a PHP script
that was already running (which she was not), why would you suggest that she
use exec() instead of include()?
I think the issue has been obfuscated. Nevertheless, she's on the right track
to making her program do what she wants to.
Win-win.

If she'd only asked about PHP, include() would be the answer, but she
also included C and Perl in the options.

I thought I'd take the time to make a download limitation script, but even
though the idea of this script is 'simple', it 'simply' refuses to work
entirely properly.
Basically I setup a real quick timelimit, $time_limit should mean 'within
the last 20 seconds'. What I am looking for is the following:
a user requests a link via the script, i've got all that part right. what we
do first is check to see if there is info in the db about the user who is
identified by their ip. if so, use it to calculate stuff, if not, download
the file, record their ip and update the download counter by 1.
what i want to happen is only allow a certain ip to download a max of 2
files per give time period.
the problem is the script 'works' as expected if i replace
------------------------------------------------
else
{
mysql_query("UPDATE ip_limit SET downloads = 0 WHERE
userip = '$userip'");
//$dl = true;
}
------------------------------------------------
with
------------------------------------------------
else
{
mysql_query("UPDATE ip_limit SET downloads = 0 WHERE
userip = '$userip'");
echo "we updated the db successfully!";
}
------------------------------------------------
.
But if i replace the echo "we updated the db successfully!"; with $dl =
true, (because I want there to be a download right after this reset, rather
than just a notice of a download-record-reset), then all i get is 1
download, then timeout, then 1 download, recurring.
This just defies the laws of logic, or i am insane. Here is the code snippet
that deals with the limitations (followed by the download script in "if
($dl)" - for any brave soul out there. Feel free to rewrite or suggest code
changes, i'm all ears!
------------------------------------------------
$dl_limit_perday = 2;
$time_limit = time() - 20;
db_connect($dbhost, $dbname, $dbuser, $dbpass);
$dl_limit_perday = 2;
$time_limit = time() - 20;
$get_ip_info = mysql_query("SELECT UNIX_TIMESTAMP(last_access),downloads
FROM ip_limit WHERE userip = '$userip'");
$ip_info = mysql_fetch_array($get_ip_info);
$last_access = $ip_info['UNIX_TIMESTAMP(last_access)'];
$downloads = $ip_info['downloads'];
$time_to_wait = $last_access - $time_limit;
$has_hit_dl_limit = ($downloads >= $dl_limit_perday) ? true : false;
$has_hit_timeout_limit = ($last_access > $time_limit) ? true : false;
// if($num_dl > 3) { if($time_limit > $blah) { reset_downloads();
process_download(); } else { echo "GTFO" } } else { process_download(); }
if($has_hit_dl_limit)
{
if($has_hit_timeout_limit)
{
$dl = false;
print('<h1>Too many downloads today!<br />');
print "Time limit: {$time_limit}<br />Last time
accessed: {$last_access}<br />";
print "Time to wait = $time_to_wait seconds</h1>";
exit;
}
else
{
mysql_query("UPDATE ip_limit SET downloads = 0 WHERE
userip = '$userip'");
//$dl = true;
}
}
else
{
$dl = true;
}
if ($dl)
{
mysql_query("REPLACE INTO ip_limit (userip,last_access,downloads)
VALUES ('$userip', NOW(), '$downloads'+1)");
download_the_file();
}
else
{
exit, etc
}

You do realize that the code in this block below is only accessed
if $downloads is greater than or equal to $dl_limit_perday, correct?

As a result, only when it meets that condition does it set $dl to
TRUE for the next block.

Yep, I realise it - that's exactly the bahaviour I expect...if the user has
hit the download limit, then the script uses the inner
if($has_hit_timeout_limit) stament (relating to the timeout), and keeps
doing so on each request until the timeout is over (since download value is
still over the limit for each request) - until at which point the inner if()
statement should reset the downloads to 0, and then download the file, and
increment the downloads column up by one again.
but for some reason, if i try to put $dl = true after the UPDATE (in the
inner if($has_hit_timeout_limit) statement), the download works, but the
UPDATE never happens, so i get an ever-increasing value for 'downloads' in
the db, and only 1 download, then timer, then 1 download, then timer, etc.
it really is bizarre! :(

Sure, go ahead -- it's one of my favorite sayings.
Woody Allen used to say that he never wrote his clever remarks, but
rather they just popped out. With me it takes a bit more effort -- I
spend a significant amount of time trying to be clever for if I
actually was, I wouldn't need to waste the time.
In any event, I think my best saying was:
"I've learned something new every day of my life, and I'm getting
damned tried of it."
You see, I'm assembling a list of my wit for posterity and hope to
pick one out for my tombstone. I told my wife that should I die
before current expectations are finished, she could use:
"Always on the edge of greatness"
I think that does a good job of summing up my contribution. :-)

Whereas mine will say something like </cruelWorld> or </Dan> or
something of the like.
Perhaps even:
<?php
function dan($dateOfDeath) {
return "Daniel P. Brown: 01-01-1970 - ".$dateOfDeath";
}
die(dan('00-00-0000'));
?>
With the actual dates in place, of course. ;-P
I should go back through the Brainteaser thread from Spring 2007
and see what other kinds of geek-wit there were. Inspiration for a
Tombstone. Sounds like an artistic piece. ;-P

Hi,
There are plenty of things that cross my mind about this:
A simple end of script tag:
?>
But that is really vague of course.
Another would be:
function life(&$user) {
while($user->days_on_earth !== COUNTED) {
$user->do_stuff();
}
$user->disconnect();
}
Endless things possible with programming metaphors.

So... is this like the opposite of a "Hello world" program? Perhaps a
"Goodbye world" program? :) I want something like "Download complete" or
"Buffering" on mine.

That will always evaluate to TRUE because you're setting the

Greetings,
I have a problem with iconv(), and I need help solving it.
Here is the background:
I have a Web page with a Form that saves data to a MySQL database. I
need to retrieve the data from the database and create a PDF document
with FPDF.
The Web Page, the database, and the browser are all set to UTF-8, so I
have to convert the data from the database to ISO-8859-1 in order to
have FPDF show it correctly. I am using iconv() to convert the data.
It works like a charm for the data acquired with text boxes, but it does
not parse the data acquired from textareas correctly.
For example:
I have an text input (<input type="text" />) and a textarea
(<textarea></textarea>).
I type the string "sometextàèìòùésomeothertext" on both the input fields
and save it into the database through POST.
If I retrieve the data and show it on a web page, it shows correctly. I
then create the PDF with FPDF parsing the data with the following
instructions:
iconv("UTF-8", "ISO-8859-1", $inputText)
iconv("UTF-8", "ISO-8859-1//TRANSLIT", $textarea) or iconv("UTF-8",
"ISO-8859-1", $textarea)
The PDF shows the first record correctly, while the second only shows
"sometext"
If I use
iconv("UTF-8", "ISO-8859-1//IGNORE", $textarea)
the PDF shows "sometextsomeothertext" skipping all the special chars.
Why is the textarea behaving differently than the text input? Is there a
way to fix this?
I would really appreciate any help, thank you.
Stefano
