Re: [PHP] problem reading sessions
yup, it's set correctly. It actually creates the file (I've opened it in a
text editor) with the correct variable names, but just no values.

Have you set the session.save_path properly in php.ini ? By default it is
set to /tmp which doesn't work under Win* systems. You need to point it to
a
valid directory on your machine.

[PHP] Strange Session Issues
I posted a question earlier, but I don't think I explained my problem all that well. I am having problem with sessions on my W2K box. I can start sessions and register variables but I can't, however, seem to get the contents of the registered variables written. When I open the session file (the actual physical file located on the server), this is its contents: !sess_user|!blah|!sessUserClass|!sessFormData|!oUser| Each of those variables should have some data associated with them. Please note that I have not added the '!' to the variables. I don't think I am having file permission problems because some data is actually being written. The only data missing (and the most crucial) is the contents of each those variables. Does anybody have any suggestions?

With it off, session_register() is not needed. Also, session variables
must
be accessed thru the $HTTP_SESSION_VARS[] array. Try this code:
test_session1.php
?
session_start();
$HTTP_SESSION_VARS['blah'] = good;
?
test_session2.php
?
session_start();
echo session_is_registered(blah) . br;
echo session_encode(). br;
echo isset($HTTP_SESSION_VARS) . br;
echo sizeof($HTTP_SESSION_VARS) . br;
echo $HTTP_SESSION_VARS['blah'];
?

Hm... I tried quite a few variations on this. I can't seem to get any

function get_current_page_name()

$current_page_name = $current_page_name[-1];

Nothing.
The only thing that works is $errorcode =
basename($_SERVER['PHP_SELF']), but that's not the point -- I still
don't understand why the function above doesn't return anything. In
this case, I'm positive that I've specified the last element of the

RE: [PHP] mktime() into TIMESTAMP ?
Just make sure that whichever way you choose, you always use the same style, so things don't get messy. Personally, I always use INT(11) MySQL columns and store the unix timestamp and this makes things easy for me. The only exception is when storing dates that are before 1970, but I very rarely have to do this. In the end, I guess it depends if you want to do the formatting of the date field when you're inserting the data (use TIMESTAMP) or when you're pulling it out (use INT).

PHP's mktime() function uses a timestamp that is the number of seconds since the Unix epoch. MySQL uses the MMDDhhmmss format for its TIMESTAMP column type. I'm not complaining that they're not the same, but curious as to which I should use for storing timestamps -- does it matter? PHP has a lot of nice formatting conventions with date(), so I am leaning towards using mktime() to store PHP-style timestamps into a MySQL TIMESTAMP column. But MySQL does have the ability to format dates, and its TIMESTAMP column type bumps up if I don't manually insert a value. Any suggestions? Erik Erik Price Web Developer Temp Media Lab, H.H.

There are a few things that it could be.
Change the ereg_replace to str_replace
Try adding Host: $server_name on the line after the GET:
fputs ($fp, GET / HTTP/1.0\r\nHost: $server_name\r\n\r\n);
iirc, if the server uses virtual hosts, the GET won't work properly without
it.
If that's not it, try adding this instead of your single echo line:
while (!feof ($fp)) {
$line = fgets($fp, 4096);
echo $line;
}
As that will return and echo all the page, not just the header.

[PHP] OT - representing data
Hi All I have over 26000 urls in a table. They are all urls and query strings of hits to the same 10 - 20 sites. I need to have a way to allow the user to select one of these, and then do some processing on it, and I'm struggling to find a way. I did have a select dropdown with a list of them, but that has become unmanageable, even when coupled with a restrictor text box. For example, the user types 'david' in the restrictor, and then the dropdown only lists those urls with '%david%' Has anyone got a genius way of allowing the user to select one easily and without having to download all 26000.

[PHP] Problem with readfile
Hi all I am using the following to pass a file to the client snip header(Content-type: . $row['filetype'] ); $path = ROOT_PATH . file_uploads/; $real_filename = $path . $row['location'] . '/' .$row['filename']; header(Content-Disposition: attachment; filename= . $row['filename']); readfile($real_filename); /snip The content type is obtained from a database along with the actual location of the file. The files are outside of the webroot. The problem is that the file is either corrupted or something different is sent. E.g. if a pdf is sent the first line of the received file is %PDF-1.3 followed by some unprintable (in a 7 bit email) characters, this causes adobe to report an error. If a text file is downloaded, then all I get is the source of the webpage I called the function from. Where am I going wrong? I have checked the pathnames and the headers and all seems to be correct. The browser produces a dialog with the correct information in it, i.e what file type and the name.

[PHP] Problem retrieving URLs
Hi all
I am having a few problems retrieving URLs from within PHP. I am using the
following to get the URL
?
$lines = file($URL);
foreach ($lines as $line_num = $line) {
echo Line #b{$line_num}/b : . htmlspecialchars($line) .
br\n;
}
?
It works fine even for .htaccess protect areas unless I need to change ports
i.e I need to get some data from a server on port 81 instead of port 80. I
get the following back from the script. The second warning I'm fine with as
there is obviously nothing coming back, but the first has got me stumped.
Any ideas?
(I've masked the URL)
Warning: file(http://www.xx.uk:81/;) - Success in
/home/sites/site70/users/afrench/web/get_test.php on line 3
Warning: Invalid argument supplied for foreach() in
/home/sites/site70/users/afrench/web/get_test.php on line 5
The server is a cobalt with PHP v4.1.2
Thanks
Alastair French

RE: [PHP] a generic getsql() function
Thomas Hochstetter wrote:
Hi guys,
I wrote a generic getsql() function for my project's class. However, I
only manage to retrieve a single row. What it should really do is:
Read all rows into the array (with multiple results). The code is
below:
function getsql($sql,$conn,$dbase,$arr)
{
if($conn)
{
mysql_select_db($dbase,$conn);
$result = mysql_query($sql,$conn);
while ($arr = mysql_fetch_assoc($result))
{ return $arr;
// Something has to happen here!!!
}
}
I think your problem is that you are returning after the first row has been
read, what you need to do is add the row ($arr) to another array using
$new_array[] = $arr or similar. and then move the return $arr to after the
while loop, but then return $new_array not $arr.
Hope this makes sense.
