I had 4.0.0 for a year or more and used that stuff quite well.
And the docs says :
"For earlier versions of PHP, you'll need to do something like
the following.
Note: This will not work in versions of PHP 4
after 4.0.2. It depends on internal functionality of PHP which
changed after that version."
If one of your boxes is 4.0.2 and the other 4.0.3 use the output of phpinfo() with
some kind of hack to determine wich one of the
function to use, or just write a wrapper which decides pipe to which function to make.

Hi. I've got the following problem. I've taken over a website of about
1200 static pages. Yes, that's right, 1200 static pages. Containing
roundabout a zillion working and broken links. I've done my job and made a
system that actually works, importing each page (manually with a
publishing tool written for the occation in PHP), adding the metadata
needed for nice searching and presenting in the three languages I need to
support, and actually got the system working. (yes, I will probably be
writing an article about the lot, because it contained multiple fun
challenges (and of course the bit about 1200 pages routine work :-/ ) ) To
finish off, I've got one last barrier. All these pages contained links.
Because I've actually categorized the information, in addition to the
already broken links, most are now totally broken. I've set up a handler
that takes care of the most 'duh'-style breaks (like index.html now being
index.php), but I've still go to go through all these funny links and
change them. Because I'm a user at the box, not root, and the webserver
owns most of the documents that I've only got read-access to, I need to
make a script that reads the document, extracts all the links (a href and
img src mainly) and lets me edit them. Does anyone have a decent regex
string that would allow me to get all the links and then do a
search-replace through the document to put in the correct ones?
Cheers
Nik

Hy,
I would like to know if there is a way to get information on the include
hierarchy of files in php, especially to find out where which file is
included and trace back the line from some file until the first called
php file.
My special case here and now is that I get an error that some function
is already declared and cannot be declared again because of this.
I know i must have included the file with that function somewhere
already, but as i have lots of nested includes I have trouble right now
to find the place where ist already happens.
I know I can prevent those things in future by using things as
require_once and so on, and i can search through all the code, making
yself a map on paper to see which file includes what, but what i really
want to know is, if i can ask some function to tell me where the
function which makes the error stated above and from where the file is
included, and from where this file again is include, going as far back
until i have my first-called php file.
I hope you can understand what i mean,
henning

Don't think that a option like this exists.
But maybe you should consider using
include_once or
require_once
Also before you define the function use the function_exist("") and if the
function already exists don't redecleare it.

That's what I wrote - I know I can use things like that, but I am
curious if there are other ways to find out which file is included by
what and which function is defined in which file - i didn't find answers
about that in the manual.
Meanwhile I found out what the real problem was, namely that a function
was declared inside a function, and the parent function was called
twice, resulting in an error. I think it's generally not recommended to
declare functions inside functions as I see no obvious reason now when
this should be useful, only that it can make things complicated as i saw
right now.(btw: this code does not come from myself, i am just making
additions to it)
So, I am still curious if and how one can trace function definitions and
includes in a convenient way.

I'm not sure if there is anything built in that you can use, but you
probably should start with the:
__FILE__ and __LINE__
constants. The __FILE__ constant is the name of the script file being
executed. If it's in an include file, it will be the name of the include
file, not the parent file. The __LINE__ is the current line within the file
(include).

Ok, tested it and to my surprize it does work. But why?!
Questions:
1. $letter++ -- why doesn't this evaluate $letter as integer before
incrementing?
2. print $letter++ -- why doesn't this evaluate to "b" at the first loop when
it's already 'a'? Ok, this I may be able to explain because it's neither "print
++$letter" nor "print ($letter++)", but I wouldn't have trusted this syntax to
work this way a million years!
Nice, elegant code indeed! Apologies for doubting it! :-)

Another idea, run a script that opens a file and flocks it until it's
executed. I am sorry if this is dumb as I have little experience on locking
files, but, I guess if it's locked it won't get opened again and executed
(via include() or eval());

There may be a much easier method however why not write a file and then check for it's
existence on the next execution. Delete the file at the end of
execution to clear the way for the next pass.
Quick and dirty so probably at least on typo
<?
$pidFile = "path/to/file/filename";
if (!is_file ($pidFile)) {
touch ($pidFile);
// code to execute
unlink ($pidFile);
}
?>

I was thinking about this solution, but what can I do if the script ends
prematurely. The file will never be deleted ??
Anybody has an example of how to use flock ?

Nicolas,
You could try something like
<?
$pifFile = "/path/to/file/filename";
if(file_exists($pifFile))
{
$fp = fopen($pifFile, "r");
flock($fp, 2);
// your code
fclose($fp);
}
Note: Just wrote it, not tested.
Note: You would probably want to do somethig more graceful then simply rely on the
file existing... like create the file if it doesn't exist and then lock it.
Note: From the manual - flock() will not work on NFS and many other networked file
systems. Check your operating system documentation for more details.
On some operating systems flock() is implemented at the process level. When using a
multithreaded server API like ISAPI you may not be able to rely on flock() to
protect files against other PHP scripts running in parallel threads of the same server
instance!

It's a nasty hack, but you chould run a separate shell script to
check for the existance of the running script, then call the script
if it's not running.
something like (/bin/sh):
PID=`ps aux | grep [program] | grep -v grep | awk {'print $2'}`
Replace [program] with the program name.
That'll get you the PID if the script is already running. You can kill
it, or just exit instead, for example. That's one way..

I tried echo %PATH% > test.txt and both the webpage and the dos prompt echo the
correct path information. This shows that a batch file executed by php can access the
system vars. They have a diffence only in accessing the %USERNAME% variable. Could
this be indicative that it is running as the system user? If so how do I change that?

And see if the information you want is in there anywhere.

Hi Brian ,
I 've solved the problem :)... :)... :)... :)... :)... :)... :)... :)... :)... :)...
:)... :)...
:)... :)... :)
I installed version of php 4.0.7 (php-4.0.7rc1-win32.zip) ;
1- I extracted zip package ,
2- I copied (also configured) php.ini file to my \winnt folder. (with php_gd.dll and
php_mssql.dll)
3- I copied php4ts.dll to /winnt/system32 driver (it's important for isapi)
4- I copied ntwdblib.php to /winnt/system32 driver (it's important for MsSQL 7.0
extension)
5- I configured IIS to run php extensions with isapi .
6- I started the IIS service and I tested with my basic code which uses GD library .
7- And...Dadaaaaaa.... Everything is worked....
I think php 4.0.6 (which makes me crazy) have a problem with GD library.
Sincerely.

OK, then give this a try:
sysctl -w kern.maxfiles=8192
sysctl -w kern.maxfilesperproc=8192
(or however high you want to go)
And it may need a reboot; I dont know if that would take effect
immediately (check it with ulimit -n after you do it). If it works,
you might have to stick that in rc.local in order to get it to stick
whenever you reboot.
Again, I don't know if that'll have any effect..

I'm sure you've checked to see if the mysql server is running..
The socket should be owner:group mysql (or whatever user you set up to
run the mysql server).
Are you trying to access it via PHP or just the command line?
If it's PHP, you could try altering mysql.default_socket in your
php.ini to what mysql expects. Run mysqladmin and check to see where the
socket is:
mysqladmin -u root -p[password] variables
Replace [password] with your real password.
Otherwise, you can set it by altering $MYSQL_UNIX_PORT in your
safe_mysqld script, or in whatever file you're using to start mysqld, to
please PHP, but it may break other applications that depend on it being
somewhere else. Check those scripts, they're probably defining the socket
in there somewhere.

Hello all!
I've wrote to scripts that use Javascript too. The idea is to have a parent
window teste_popup.php4 and a child window pop.php4. When a link is clicked
on the parent window, the child window will open. After the user enters
information on the child window he must close it and that will update the
parent window.possibility to me.
But there's a little problem,though.
The only browser that it works is MS IE. It does not work on
Nestcape (Win or *NIX) or Konqueror (*NIX).
If I try it on a different browser, say Netscape or Konqueror, when I click
the main window to open the popup window it does work.
The thing that does not work is when you click close on the popup window. It
does not close the popup window and if I close the window it does not update
the parent window.
I've written two test PHP scripts teste_popup.php4 (the main window) and
pop.php4
that I am including below. Maybe someone can help me out by pointing where
it is
wrong.
teste_popup.php4 (parent window script)
<?php
// teste_popup.php4
print("<html>\n");
print("<head>\n");
//print("<script type=\"text/javascript\">\n");
print("<script language=\"JavaScript\"><!--\n");
print("function newWin(urlLoc) {\n");
print(" _winName=\"Janelateste\";\n");
print(" _info = \"toolbar=no\";\n");
print(" _info += \",location=no\";\n");
print(" _info += \",directories=no\";\n");
print(" _info += \",status=yes\";\n");
print(" _info += \",menubar=no\";\n");

print(" _info += \",width=640\";\n");
print(" _info += \",left=200\";\n");
print(" _info += \",top=100\";\n");
print(" DispWin=window.open(urlLoc,_winName,_info);\n");
print("} \n");
print("//--></script>\n");
print("</head>\n");
print("<body>\n");
print("<p>\n");
print("Esse e um teste usando Javascript para montar as janelas\n");
print("a parte de numero de operacoes, pecas, etc de garantia.\n");
print("</p>\n");

print("<br>\n");
print("</body>\n");
print("</html>\n");
?>

print(" window.close();\n");
print("} \n");
print("//--></script>\n");
print("</head>\n");
print("<body onunload=\"JavaScript:oldWin('teste_popup.php4?oper=1')\">\n");
print("<b>\n");
print("Child window\n");
print("</b>\n");
print("<br>\n");
print("Parametro oper = ".$HTTP_GET_VARS["oper"]."\n");
print("<br>\n");
print("<a href=\"JavaScript:oldWin('teste_popup.php4?oper=1')\">Close e
Update</a>\n");
print("<br>\n");
print("</body>\n");
print("</html>\n");
?>
Could anyone help me out to adapt it to any browser?
Thank you very much and merry christmas,

I don't know if this is it, but you may:
1. Replace
print(" returnwin=window.opener.navigate(urlLoc);\n");
with
print(" window.opener.location='urlLoc';\n");
2. Try opening the pop-up widow with Netscape allowing the location input box to
appear, click on "Close e Update" and, if it doesn't work, type "javascript:" in
the location bow -- then check for errors reported by Netscape. 9 cases out of
10, if you solve the problem with Netscape, Konqueror will work as well.
Please let me know of your progress - I'm curious what the problem is.

Hi i've taken a look throught he manual and i can't find a function to do

You'll have a lot of problems, though, because
1. You also need to check for <script type="text/javascript">;
2. You have to strtolower() both strings in order to eliminate capitalization
differences;
3. and the tougher: how do you check for this one:
"<script language ='javascript' \t>", where "\t"
is a tab character? And obviously all the possible combinations...

Hello Bogdan,
I greatly appreciated your help. Now it is way better but some behaviours are
still weird as I describe below:
On Microsoft Internet Explorer:
- If you close the popup window by clicking the close icon, the onunload
event works just fine.
- If you close the popup window by closing on the link it reloads the parent
window twice, which is not good because the parent window that I need it to
be done reads info from a database and this can be time consuming. What
happens here is that it calls the oldWin function and then the onunload event.
On Netscape and Konqueror:
- if you close the popup window by clicking the close icon, the onunload
event is not called or recoginized. I wonder if I need to register the events
with captureEents. If so, how can I do it?
- If you close the popup window by closing on the link it reloads the parent
window once since it does not recognize the onunload event.
There should be a way by creating a variable or whatever that would not call
the oldWin function twice if the onunload event is fired.
Do you know how to do it?
Could you help me with that?
Thanks again.
regards,
Carlos Fernando.

Thank you very much and merry christmas,

The way it looks to me, you do both the window opening sequence and the closing
procedure twice:
- Window opening: you specify window options (toolbar, status bar etc) once in the
window.open() call and once in the actual window code;
- Window closing: you perform the same actions once upon clicking on "Close e
Update" and once upon actual window closing (via onUnload()).
Try implementing both procedures only once in a way that they're ran by both types
of browsers.
AFAIK you don't need to implement any kind of captureEvents, but I may be wrong
about it.
Only now did I read your final paragraph: I think you'd better leave the
onUnload() in place and only window.close() in the link, which should trigger
onUnload(). Hope this works with NS 4.x!
I don't have any clue why closing the pop-up via Windows controls both doesn't
trigger onUnload and reloads the parent window -- are you sure you're not wrong
about this? I mean, if it reloads the parent window, doesn't this mean that
onUnload() works?
My suggestion is fiddling with the onUndload() function triggering it via a link
(as suggested in the previous message -- with a href="javascript:oldWin()") until
you get no error messages when accessing "javascript:" in Netscape. You didn't
tell me -- do you get any more error messages now upon accessing "javascript:"?

Hello,
On this list yesterday: "As long as these tools are out
there, it should keep all of us on our toes, and programming with security
constantly on our minds."
Today i have tested, Smart HitBot (http://www.hitbot.f2s.com/). Bad stuff
for stats, toplist, searchengines etc.
Now i want filler out this requests. Do you have some ideas?
I will start with a simple script, say:
<?php
include("counter.php");
if(!real_one()) $counter-=2;
$counter++;
$fp=fopen("counter.php","w+");
fwrite($fp, <?\n \$counter=$counter; \n?>");
fclose($fp);
?>
Maybe i can do something with the interval between 2 requests, with real
users this should be 'random', someting like:
<?
function real_one()
{
include("real.php");
if ($interval==0)
{
$interval=time()-$last;
$last=time();
}
else if($interval==(time()-$last))
{
$interval=0;
$last=time();
}
else
{
$interval=time()-$last;
$last=time();
}
$fp=fopen("real.php","w+");
fwrite($fp, <?\n \$interval=$interval;\n \$last=$last; \n?>");
fclose($fp);
return $interval;
}
?>
It's something, but not safe. one real user between two fake -> count 2
fakers.
If have also looked at $HTTP_USER_AGENT:
--
request1:
Mozilla/4.0 (compatible; MSIE 5.01; Windows 98)
request2:
Mozilla/4.0 (compatible; MSIE 5.0; Windows 98)
request3:
Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)
etc.
--
So this will always start with "Mozilla/4.0 ("
This will be the same as the header from IE6.0 installed on the same machine.
It will be different from faker to faker(???) depending on the installed
browser(s).
Thanks for your help.

When reloading php software to new directories deleting the old dir is
often difficult because there is a dot file (often with a majic quotes
directrive) so directories aren't empty. I have to telnet to my main
account and use command line ftp to delete the (still invisible)
offending dot files. Then I can delete the dir with my standard ftp
client.
I know that I have seen unix systems where I can view/delete dot files
with an ftp client. Is that under my control (I have user unix access)
or system only control? It's linux/apache.

I am having a problem moving files uploaded using POST.
What is supposed to happen is it takes two files, a picture and its
associated thumbnail, both of which have been uploaded via HTTP POST, and
moves them to two different folders, renaming them appropriately.
Here's the code...
-----------------------------------------------------------
BEGIN CODE FRAGMENT
-----------------------------------------------------------
function upload($pid) {
GLOBAL $siteroot, $HTTP_POST_FILES, $fileroot;
// more manageable variable names to work with
$picfile = $HTTP_POST_FILES['picfile']['tmp_name'];
$thumbfile = $HTTP_POST_FILES['thumbfile']['tmp_name'];
$pic = $HTTP_POST_FILES['picfile']['name'];
$thumb = $HTTP_POST_FILES['thumbfile']['name'];
// check if *pictures* were uploaded, as opposed to some other file type
if(!$picsize = getimagesize($picfile) || !$thumbsize =
getimagesize($thumbfile) ) {
$error[] = "Either the picture was not uploaded properly, or ".
"it was not a valid picture. Please hit 'back' and try ".
"again.";
}
// get the file extension of the pictures
$picext = strstr($pic, ".");
$thumbext = strstr($thumb, ".");
// create the filenames pictures will be stored under
$picname = "pic" . $pid . $picext;
$thumbname = "thumb" . $pid . $thumbext;
// destination path for pictures and thumbnails
$picdest = "$fileroot/pictures/$picname";
$thumbdest = "$fileroot/thumbs/$thumbname";
// debug info
$message = "<b>Picture Source:</b> $picfile<br>\n".
"<b>Picture Dest:</b> $picdest<br><br>\n\n".
"<b>Thumbnail Source:</b> $thumbfile<br>\n".
"<b>Thumbnail Dest:</b> $thumbdest<br><br>\n\n";
message($message);
// security check then copy files to destination folder...
if (!is_uploaded_file($picfile) || !is_uploaded_file($thumbfile) ) {
$error[] = "Possible File Upload attack. File Upload aborted.";
} elseif (!$movepic = copy($picfile, $picdest) || !$movethumb =
copy($thumbfile, $thumbdest) ) {
// ... or quit with error
$error[] = "File could not be copied. Please retry.<br>\n".
"<b>Picture Source:</b> $picfile<br>\n".
"<b>Picture Dest:</b> $picdest<br><br>\n\n".
"<b>Thumbnail Source:</b> $thumbfile<br>\n".
"<b>Thumbnail Dest:</b> $thumbdest<br><br>\n\n".
"Picture: $movepic<br> Thumbnail: $movethumb";
}
// check for errors or write successful entry to dbase
if(isset($error) ) {
error($error);
} else {
$db = open_db();
$query = "UPDATE yb_pictures SET ".
"thumburl='" . $thumbname . "', ".
"picurl='" . $picname . "', ".
"status='3' ".
"WHERE id='" . $pid . "'";
$result = query($query, $db);
// output for user
$message = "Picture uploaded successfully. Please ".
"<a href=\"$siteroot/manager.php\">go back to the Site ".
"Manager.";
message($message);
}
}
-----------------------------------------------------------
END CODE FRAGMENT
-----------------------------------------------------------
My problem is that the script completes successfully and reports "Picture
uploaded successfully". But when I go to see if the files are there, the
thumbnail file is missing. Only the picture file appears where it should.
I have checked, re-checked and checked again for typos or other errors in
the file or directory names, and I am sure there are none.
I have no idea what could be the problem.
Go to http://www.unndunn.com/guestbook.php?action=showVersionInfo for info
about the version of PHP the server is running.
Thanks in advance!

That depends on what you want to do. You also should consider other well
thought solutions. If you are looking for a well structured framework
look at BinaryCloud ( http://binarycloud.tigris.org/ ). If you are
looking for a good database abstraction package, look at Metabase (
http://phpclasses.UpperDesign.com/browse.html/package/20 ).
Unlike PEAR-DB and PHPlib, Metabase provides true database independence
to your applications. This means that with Metabase, you do not have to
handle database differences with database specific code in your
applications. For instance, each database may format date fields in
different ways. Metabase assures that all date values that go back and
forth the database are formatted according to the ISO 9601 format
(YYYY-MM-DD), regardless if the underlying database uses that format to
represent dates or some other.
There are other nice features like the ability to install your database
schemas just by defining your tables, fields, indexes and sequences in a
custom XML format that is database independent. Just take a look in the
page above to learn more about it.

Manuel Lemos

Actually - no. Querys/conformance to specs/sequences/stored procs and more
are different from DB to DB. While the abstration layers help a little, they
really don't help a lot.

I have recently been requested to choose new technology to be used within my

toward PHP. The one thing I really need to know is how many concurrent

corp and I need to know that PHP can scale at the level that I need it to.

JSP is going to be faster as these objects are all ready created & loaded
(apparantly according to the Sun Micro Systems guy) php however is more
likely to be on a external webserver. Probabily not that much help but

Hello everybody!
Apart from the usual best wishes for 2002, I have a question: does
anyone know of a good security list/newsletter/bulletin for PHP?
Actually, any kind of good source would be great, even if it's net
security in general -- what I'm looking for is:
1. Mostly PHP security (including PHP packages with vulnerabilities)
and
2. A good source (I'd like to subscribe to an active
list/newsletter/bulletin so they publish info from other sources as well
-- not only original data they found out without any external info).
Too much to ask? :-)

Hello Bogdan,
Before anything, thank you!
I've installed Netscape 6.2 on a Linux box and it works just like MS IE.
Just like I told you. The unload event does not work or is called by either
netscape 4.x or konqueror.
But it is called by Netscape 6.2 and MS IE 5.x & 6.x.
I think that JS implementations on those browsers might be quite different.
I wonder how to make the onunload event work on Netscape 4.x and Konqueror.
That's why I thought creating a captureEvents.
Also a good thing would be creating a popup window without the close (X) and
minimize ( _ ) icons since I can only create it without the resize and
maximize buttons. Do you know how to create a java popup window without the
close icon? If it is possible the problem is solved since the only way a
user could close it is by clicking on the link.
Thank you,
Carlos Fernando Scheidecker Antunes.

I don't have any clue why closing the pop-up via Windows controls both
doesn't
trigger onUnload and reloads the parent window -- are you sure you're not
wrong
about this? I mean, if it reloads the parent window, doesn't this mean that
onUnload() works?
My suggestion is fiddling with the onUndload() function triggering it via a
link
(as suggested in the previous message -- with a href="javascript:oldWin()")
until
you get no error messages when accessing "javascript:" in Netscape. You
didn't
tell me -- do you get any more error messages now upon accessing
"javascript:"?

Hello, Carlos!
1. onUnload IS called by Netscape. Didn't test it with Konqueror, but I guess
it's called as well;
2. My guess is that you have a problem with the function itself, that's why I
strongly suggest you define it as a standalone function and use "javascript:"
for debugging;
3. No, there's no way to create a function without close buttons -- which is
quite normal regarding W3C... Would you like amazon.com to be able to open a
browser window you can't close? :-)

Hi, I am running PHP 4.10 off my Win2000 box, and I am trying to upload a
file to it (Apache is running off the same box I'm uploading from).
I have the following form:
=============
<FORM method="POST" action="catalog_admin.php?action=additemsave"
enctype="multipart/form-data">
<INPUT type="hidden" name="MAX_FILE_SIZE" value="10000">
<INPUT type="file" name="userfile">
<input type="submit" name="additem_submit" value="Add Product"> <input
type="reset" name="reset" value="Reset Form">
</FORM>
============
and the php script that handles it:
============
<?php
$sql = "INSERT INTO products (category_id, item_name, item_company,
item_price, item_listprice, item_discount, dimensions_height,
dimensions_width, dimensions_length, dimensions_weight_lbs, number_in_stock,
product_description)
values('$category_id','$item_name','$item_company','$item_price','$item_list
price','$item_discount','$dimensions_height',
'$dimensions_width','$dimensions_length','$dimensions_weight_lbs','$number_i
n_stock','$product_description')";
$result = mysql_query($sql, $dbconn) or die(mysql_error());
$item_id = mysql_insert_id();
$array = explode("/", $userfile_type);
if ($array[1] == "pjpeg" || $array[1] == "jpeg") {
$array[1] = "jpg";
}
$ext = $array[1];
$new_file = "$imagedir" . "\\" . "$item_id.$ext";
if (!move_uploaded_file($userfile, $new_file)) {
$sql = "DELETE FROM products WHERE (item_id = '$item_id')";
$result = mysql_query($sql);
metadie("Unable to move the uploaded image file to the new directory
($imagedir) ($new_file) ($userfile). Image type was ".$array[1]);
}
$sql = "UPDATE products SET image_src='$new_file' WHERE (item_id =
'$item_id')";
$result = mysql_query($sql);
?>
==========================
My problem is, whenever I upload an image, $userfile is always "none". I
know I'm uploading it on the form end, but it doesn't seem to register it on
the PHP script's end. Any help here?
Thanks,
David Balatero ([EMAIL PROTECTED])
