Re: [PHP] apps that need register globals 'on' and others require
Addressed to: Philip Olson [EMAIL PROTECTED] [EMAIL PROTECTED] ** Reply to note from Philip Olson [EMAIL PROTECTED] Tue, 30 Apr 2002 22:45:49 + (GMT) Btw, I can't think of a reason why a script designed with register_globals = off would not work with it on. Which is why assuming register_globals = off will make your scripts more portable. I can. Sessions. I believe that if register globals is on PHP looks at the global variables to write registered variables else it looks to $_SESSION. I did not track down the exact reason I can't use $_SESSION with register_globals = on, I just dropped back to using session_register(), but I did have a problem.

Re: [PHP] Producing images in different sizes
Addressed to: Miguel Cruz [EMAIL PROTECTED] [EMAIL PROTECTED] ** Reply to note from Miguel Cruz [EMAIL PROTECTED] Sat, 27 Apr 2002 19:11:46 -0500 (CDT) I'm guessing the issue is that it complicates the process of adding new images, because someone has to create and upload two corresponding files. This way, they get the benefit of rapid page generation combined with a simpler administration process. miguel Who said anything about UPLOADING two images? My understanding of the question was that he wanted to: store only one copy of each image - full size. and resize it down to the thumbnail size before sending it, IMnsHO, that's crazy, unless you have a very large number of images with very few repeat visits to their thumbnail pages. I agree, it is just as crazy to expect the user to do the thumbnail creation. ImageMagick does a great job of this, but it should be done when the file is uploaded, not every time an image needs to appear on a thumbnail page. It might not be that bad with 400X400 initial files, but resize time on my server for a mega-pixel JPEG from my digital camera is about 10-40 seconds which you might get a photo uploader to sit thru, but way too long for a visitor to your site.

For instance, my file is basically just thousands of temperature
values, taken 4 times a day, over a period of 20 years. Let's
say I wanted to get a year's worth of temperatures, from the 10th
year into the file (so I would need the 4x365x10) th temperature
value from the file.
I don't quite understand what you are doing, but this might be close.
If not, give me more information on the source data, how you want to
select which days to inspect, and what you want to do with the output.
This code reads from a file that contains thousands of temp records back
to back, with no separators and displays all the temps, one day per line
for each day within a range of day numbers. Display is to a web page
and not very well formatted.
# Set these to fit your situation
$TempSize = x; # Length of temperature value in bytes.
$TempFormat = '???'; # Unpack format string for a single day.
$FileName = 'tempfile.data';
$StartDate = 365 * 10; # Start of tenth year
$EndDate = 365 * 11; # Start of eleventh year.
# End date is not displayed
$BlockSize = 20; # Set for good performance/memory use
# Here goes...
$F = fopen( $FileName, 'rb' );
$DayLength = 4 * $TempSize;
for( $I = $StartDate; $I $EndDate; $I += $BlockSize ) {
$SeekPos = $I * $TempSize;
if( ( $I + $BlockSize ) $EndDate ) $BlockSize = $EndDate - $I;
fseek( $F, $SeekPos, SEEK_SET );
$Data = fread( $F, $BlockSize * $TempSize );
for( $J = 0; $J $BlockSize; $J ++ ) {
$DayPos = $J * 4 * $TempSize;
$DayData = substr( $Data, $DayPos, $DayPos + DayLength );
$DayTemps = unpack( $TempFormat, $DayData );
echo Day: , $I + $J, - ,
$DayTemps[ 1 ], ,
$DayTemps[ 2 ], ,
$DayTemps[ 3 ], ,
$DayTemps[ 4 ], BR\n;
}
}
This is not tested, but should be pretty close. You may have to add or
subtract one from some of the control conditions in the ifs or the
places where I setup values.

The problem I was having was basically as you understood, except for the fact that I don't really have access to file at the time that I need to unpack the data from it. The file is stored in terms of Oracle bFile pointers, so basically I have some code that does like: //do query to get bfile pointer ... $bindata = $bfileptr-load(); Now I have a string representation of the binary file. At this time is where I having the difficulties. I need a way without the use of fseek(since I don't have a file, I only have a string representation of it) to select a particular subset of the data. Any advice you have would be greatly appreciated, and thanks for replying to my original post. You should be able to use substr() to get any part of the returned $bindata you want. Just use the byte position equations from my last post to determine where in the data you want to return. I think your dba may be crazy to store that much data that way.

Addressed to: Jen Hall [EMAIL PROTECTED] [EMAIL PROTECTED] ** Reply to note from Jen Hall [EMAIL PROTECTED] Tue, 20 Mar 2001 19:59:26 -0500 Hi there I am trying to build an application where a user can use an HTML form, fill out some fields, select a file from their hard drive, and have it emailed as an attachment with the contents of the form. (essentially, fill in your name and address, use my module to attach ms-word file of your resume, send email of all). I am able to make it work with an image as the attachment, but when I select an MS-WORD document, which is the goal of this application, it still thinks it's an image, and doesn't work properly. Emailing a .doc file is a VERY BAD idea. VB for applications which is embedded in word is very powerful. What happens when some hacker decides to use your page to send a vba script like the naked wife virus thru your program? Oh, here is a resume... lets take a look. Open the attachemnt. A burst of network activity while the vb script sends a copy of itself to everyone in the victim's address book. Then the hard drive light comes on as the program deletes a bunch of important files from the \windows\system directory. Finally the computer crashes because windows can't run without the missing files. Even though the machine won't boot, the computer forensics people recover the email, and trace it back to you. The victim's lawyers come knocking on your door asking for damages because you let some hacker release a virus thru your program that wiped out several computers at the victim's company, some of their customers, as well as several of his friends. You are forced out of business because the damages are more than the value of your entire company. Not good. Don't believe me? How about one of them: http://www.gcn.com/state/vol5_no11/enterprise/491-1.html http://members.door.net/kls/virusinfo.htm http://venus.soci.niu.edu/~cudigest/CUDS11/cud1120.html http://www.jwolsen.com/wtip035.htm Want more? - search for 'macro virus' on your favorite search engine. NEVER send .doc, .exe, .com, .bat or .vbs files as attachments, and never - ever open them if one is sent to you. Not even from someone you trust. Melissa, Anna and Naked Wife all depend on the fact that the virus often comes from a trusted individual as part of their tactics, and it works! Are you sure your anti-virus software is up to date?

Greetings,
I know there's been some discussion of adding support for string
indexing (that would be exclusive to strings [because it wouldn't apply
to arrays] and therefore more efficient) using curly braces
($someStr{0}, $someStr{1}, etc.).
Has this been implemented, and, if so, in what version did this first
appear?
Yes. I am using 4.0.2 and it is supported. I am not sure how long it
has been available. Currently $SomeStr[0] and $SomeStr{0} are the same
thing, but someday the [] notation will go away. Maybe php 5.

A good way to do what you are asking is a combination of the last two
suggestions...
if( count( $Area )) {# Don't do anything if there are no entries
reset( $Area );
# Handle the first one, with no 'or'
list( , $Value ) = each( $Area );
$String = "(Area='$Value')";
# Handle the rest with a leading 'or'
while( list( , $Value ) = each( $Area )) {
$String .= " or (Area='$Value')";
}
}
I have just started with php a few days ago but in the book that I am
reading it
uses a foreach loop that is specifically for arrays.
foreach($Area as $key=$value)
{
your concatination string here

Before starting your loop (but after checking there is something to work
with) use the first element of the arra to create the (Area='1') then you
can loop through the rest of the array, starting with $i = 1 and create
or (Area='$val')

Something like SELECT EventID, EventName, EventDescription, EventStartDate, EventEndDate WHERE EventStartDate CURRENT_DATE ORDER BY EventStartDate ASC LIMIT 5; How did I do? Close, very close. I belive CURRENT_DATE is a MySQL function. MySQL functions are identified by not having a space between the function name and the required ( that makes it a function. If CURRENT_DATE is actually a function (I use NOW() because it is shorter) then you need to change the WHERE clause to: WHERE EventStartDate CURRENT_DATE() If CURRENT_DATE() is not a valid function change it to: WHERE EventStartDate NOW() Both assume that EventStartDate is a MySQL DATE, DATETIME or TIMESTAMP value. If they are something else, this will not work. It should be one of these types though!!!

This is pretty much acceptable to search engines. Even better add:
Location /program
ForceType application/x-httpd-php
/Location
to httpd.conf. Then the following url will work:
http://www.somedomain.com/program/value1/value2/command.php
program _is_ the program. $PATH_INFO containls:
'/value1/value2/command.php'
I've tried setting this up, but for the life of me, I could not get it to
work.
I've never had a problem with it. I place it inside the VirtualHost
block for the host I want to affect. I've got some domains with over
half a dozen different programs that use this trick. It needs to match
the AddType value you use to enable .php, .php3, .phtml, etc to run php.
It may only work for Apache modules. Of course, you also have to reload
the web server config files after you add it. apachectrl graceful, or
apachectl restart at least.
I've just settled with including the ".php" after the program name and that
works just as well...
http://www.somedomain.com/program.php/value1/value2/command.php
--^^
That works, but doesn't look as cool.
Why do you want to eliminate all get params and cookies?
That might
have a lot of control as to what the best approach will be.
GET because they can be modified and
So can these URL based param passing schemes. Even POST
params are not all that secure from a determined hacker. All it
takes is a little work with a program to fake POST values. The
only advantage they have is taking a little more work.
Yes, I know. But that little extra work is enough. Plus, we are
going to try a few things (including encrypting; not one way)
the hidden variables. That and trying to make sure that the form
submission request originated from our server.
To make sure hidden fields stay unchanged, contat all the values
together into a long string, pass the string to md5, and store the
result as a checksum. When you get data back from the browser concat it
again, not including the md5 string, and compare it with the checksum
from the hidden values. If they are different someone has changed the
data.
You should to add something somewhat random, that only the server knows,
into the md5 input, so even an ex-employee who knows the algorithm can
not fake a checksum. The md5 checksum with a local secret is a good way
to make sure that the original md5 checksum was computed by one of your
machines. A hacker would need to know that to create a valid checksum
for modified data.
I'm still trying to
find the answer as to when HTTP_REFERER is available and
when it isn't... still haven't heard anything back on that one...
It depends on the browser. Some never send it. The ones that do
usually only send it when a link is clicked on a page. URLS entered
by clicking on a link in an email, selected from bookmarks or typed in
by hand never have a referer.
Cookies because not all users will have them turned on.
Good reason.
If you don't care about serach engines, you can just use PHP4 sessions,
and append the session ID, or compile with --enable-trans-sid and let
php use cookies when available or place the session ID in the URN if
they are not.
As I've mentioned in another post, this is *not* working. We have that
directive turned on/compiled in and it still does not append the session ID
to URLs if the user's browser does not accept cookies. I submitted a few
code samples last week that I set up to demonstrated this. Everything
looks ok in the php.ini and everything that needed to be was turned on
when PHP4 (we are using 4.0.3pl1) was compiled, but still the session ID
is not being appended to the URL.
I wish I knew what was wrong.
If you are creating the links dynamicly how about adding this near the
end of the process:
if( empty( $HTTP_COOKIE_VARS[ 'phpsessid' ] ))
echo '?phpsessid=', session_id();
Crude, but it should be effective.
There was a php bug that messed up enable-trans-sid when I first
started using sessions, so I wrote a function to create a link:
function anchor( $Title, $Href, $Params='', Anchor='', Target='' ) {
}
It kind of outputs something like:
A href="$Href?$Params#$Anchor" target="$Target"$Title/A
except that it only includes the target= part if $Target is not empty,
and only includes $Params if it is not empty. If( session_id() 0 AND
empty( $HTTP_COOKIE_VARS[ 'phpsessid' ] ) it adds 'phpsessid=' .
session_id() to $Params, with ? in front of it if $Parms was empty or
if it had a value.
I still use it in most of my php pages. Most of my links look like:
? anchor( 'Home', "http://$SERVER_NAME/" ) ?
That might be the quickest thing to do.

help! :)
I'm trying to return a list of links under associated categories from a
database table that has the fields: "linkID, category, name, url".
I'm selecting the fields and then trying to construct a multi-dimensional
array so that the correct items get put into it (and then printed out):
Why build an array, and store ANOTHER copy of all the data in memory
while the script runs? That is just a waste of memory...
SELECT Category, Name, URL FROM Links ORDER BY Category, Name;
To display them:
$OldCategory = '';
while( list( $Category, $Name, $URL ) = mysql_fetch_row( $Result )) {
if( $OldCategory != $Category ) {
print "Category Header $CategoryBR\n";
$OldCategory = $Category;
}
print "A href=\"$URL\"$Name/aBR\n";
}

Hi,
When I run the code:
?php
mysql_connect ("LOCALHOST","webmaster2","hironsc0");
?
I got error message:
Fatal error: Call to unsupported or undefined function mysql_connect() in
English translation: You have not compiled MySQL support into PHP. You
will need to re-compile, or find a different RPM. If you compile it
yourself, be sure to add with-mysql to the ./configure command.
If this is on a Windows host, look in php.ini and uncomment the line

Re: [PHP] linking to specific spot on map?
Addressed to: Floyd Baker [EMAIL PROTECTED] [EMAIL PROTECTED] ** Reply to note from Floyd Baker [EMAIL PROTECTED] Thu, 01 Mar 2001 16:39:23 -0500 Hi.. We have a city map using co-ordinates to link to specific info on various buildings, etc. The links bring up an information page with data and photos for each building locations on the map. My question is, when this information page is accessed from another direction, say a menu, can there be a link that operates in 'reverse', back to the map and the building in question? We still want people to see the map, relating to a specific building, whether they start there or end up there. I thought the map could perhaps position itself so that the point of interest is always in the center, or that it blinks, or has a arrow pointing to it. It doesn't matter what the final display looks like, just that is shows a particular location clearly. If you have a small number of locations 100 or so, and you only want to show one at a time, I'd seriously consider just making 100 maps with markers on them, and sending the right one when needed. This will be much faster to serve as there is no graphic processing involved. If you want to be able to have multiple random selections where more than one location is shown on a map, you are stuck generating them on the fiy. I would start with a stock map and use GD to draw a marker over the top of it for each location you want to hilite. In each of your database records you would record the x and y coordinates of the point on the map where the building is located. If you want to build maps with various center points and scales, and be able to plot buildings on it, you will want to store the lat and lon of the building, and store everything else using lat/lon. If you are going to do this, look for someone very good with geometry to design the math. It can get tricky trying to show a section of a sphere on a flat screen.

This will basically submit totally fabricated data to the foriegn site and possibly screw them up somehow and/or in some way. Is there any way to defend against this? Is there any way to ensure that when a form is submitted that the submission request originated from your site/domain and not somewhere else? No. There is no way to tell a clever programmer from a live human on the other end of an Internet connection.

The form page would point to the random generated script page, and the script page could delete itself after it is proccessed. You would also want a cron to delete any files in case they never bothered to submit the form. Can anyone see a problem with this? That makes it a little harder, but I can just view source and hit the page a couple of times, and I will see that the Action="" in the FORM tag changes and know I have to go back one step to get it. If I have to I can emulate a person coming in from the home page, walking all the links to the form, then entering it. I hit the page that generates the random name. It returns the random name. I use it in my following request to get the form. I fill in the form and send it. Maybe you can make it 'not worth the effort' for a hacker, but be careful you don't make it 'not worth the errort' for your legitimate visitors. The big problem you have, is if I can fill it in by hand, I can watch what passes over the network and write a program to emulate it. What a browser can do is very limited, and even things like headers that are not normaly visible when you view source are visible to a network sniffer.

You just have to keep reverifying that the client is allowed to do what they're doing. I suggest it is time to take a look at sessions: http://www.php.net/manual/en/html/ref.session.html Things get easier if you only allow a small group of people into the site. You won't be able to keep someone who knows a valid username and password from exploiting things, but you can limit the possible exploits to what you allow a user to do. I suggest you use a SSL secured server any time you are sending passwords across the net. That way they can only be intercepted by someone with access to the authorized user's machine, or someone with access to your machine. SSL is not magic, all it does is prevent someone along the way from snooping. When someone enters a valid username and password, create a session and store all the temporary data on the server. If it is never sent to the browser, there is no way for someone on the other end to modify it. A PHP session ID is a reasonably secure random number that is hard to guess. It is even harder to guess the session ID, user name and password all at the same time. That still does not stop me, a valid user who can use the system from a browser, from being able to write a script that fakes my user action. It does allow you much more control to make sure that neither me or my robot are able to do anything you don't want me to do. It's a chore I know - security usually is :( Yep!

Please forgive me if this has been covered ad nauseum, but I have searched high and low for an answer with no luck. After building PHP as a module, following the online instructions, Apache complained that it could not resolve hostnames. I got around this by using IP's in httpd.conf and making wusage do the lookups. Is there a fix for this or is it an unpleasant side effect that we must accept and deal with? The official word on the Apache config files is that you _should_ use IP addresses rather than host names. That said, I don't do it. I find the host names more understandable when I am working on the file. The problem is you MUST make sure DNS or /etc/hosts name resolution is available BEFORE you start the web server. The first thing to try is get a list of the host names that fail and do a nslookup to make sure you can resolve them. You may have bigger problems with DNS. If the problem happens only when you boot the computer, make sure you start networking ans named long before you try to start the web server. A way to side step the entire DNS issue is to list each of your web IP addresses in /etc/hosts, and make sure that /etc/resolv.conf looks in that file before it goes out to DNS. Even if you do this you need to find out why the host names can not be resolved. If the master DNS server is setup wrong, no one will be able to see the site.

In some of my files, I have a require statement to get some global stuff accessable. I also have some header() redirects. They don't work (they worked before I added the requires). I moved the require under one of the header()s and that one works now, but I can't move it under the other one because stuff has to happen before the redirect and it needs the required stuff. So my question is do require statements produce output that I can't see (which would make the redirects not work)? The files I'm requiring don't have any output, which is why I'm confused. Thanks. The most common cause of this problem is a blank line, or evan a space in the wrong place in one of the required files. The following examples will cause the problem: -- ? some code here ? -- -- ? some code here ? -- -- ? some code here ? -- -- ? some code here ?

The way I see it, this is strictly a PHP issue. *No* lookups are succeeding, not even in the log file. If I switch back to my Apache binary built without PHP, everything works. Take a look thru your Apache config files for HostNameLookups, that is probably what it is. You can set it to ON to get this behavior back. You might want to think about it a little before you do. Having this on means that EVERY SINGLE page and image hit requires a DNS lookup BEFORE the page/image is sent. If there is a problem with reverse DNS on the modem your visitor is connected to (not uncommon) they get to wait up to 30 seconds for a DNS timeout before the page will load. Not good. Consider how often you really care about what the host name is. Is it worth the extra delay for the DNS lookup on EVERY page sent. You mentioned having to have your log analyzer do the DNS lookups when it processes the logs. I say better pay for it then when it is only you waiting for results than making your visitors pay on every page and image they download.

In that case, compile php without using with-apache or with-apxs to create a php binary. Place it in /usr/local/bin or someplace in your path. There is a way to run php from cron something like: /usr/local/bin/php -q script-name.php The way I do it is a little different. In cron I specify: /path/to/php/script.php In the top of script.php, I add a special first line: #!/usr/local/bin/php -q ? phpinfo(); ? The important thing to remember here, it has NOTHING to do with Apache or CGI, you are using standard shell operations to allow php to execute scripts the same way most perl scripts, and a lot of other scripts are run.

It'll provide some basic SQL help. It's recommended to write out columns
and values (easier to make sense of).
I find SET even easier:
INSERT INTO Table SET
or
UPDATE Table SET
then
field1 = '$Field1',
field2 = '$Field2',
fieldN = '$FieldN'
That makes it very easy to keep track of what goes where. It is
somewhat new to MySQL, but anything less than a year old should have it
available.

Re: [PHP] ftp_login problem
Addressed to: [EMAIL PROTECTED] [EMAIL PROTECTED] ** Reply to note from [EMAIL PROTECTED] Mon, 19 Feb 2001 15:22:49 -0600 I wanted to check with all of you before I report a bug. Here is the problem: I am attempting to access a OS2 server via ftp. When I login on the command line as anonymous to this server it does not require a password. When I try to login via PHP (ftp_login) it requires that I use a password. When I try to just put in just any password ftp_login comes back with a login failed message. here is the error: Warning: ftp_login: User anonymous logged in. in /home/httpd/html/php/ftpget.php on line 15 You can see the message that the server is returning is saying that my login was ok but ftp_login does not return success. If anyone has insight into this please let me know, I suggest you put a password on that box, before someone else finds it! Besides being more secure, it will allow you to use PHP's ftp as it is usually used. Also, since we are talking anonymous login to ftp, you might try using an email address for a password. That seems to be a common convention. You are MUCH better off password protecting the OS/2 box: Double click on: TCP/IP Internet (LAN) - you may have to look for it in OS/2 System. In that folder, double click on TCP/IP Configuration (LAN). I know these say LAN, but things like FTP passwords will affect dial up networking too. Click on the Security Tab. Click on the Add button. Fill out the form with an explicit username/password combination, and optionally a specific drive and directory you wish to serve via ftp. The directory you specify here will be the 'home' directory for the specified user, and the only area your machine will serve files from. If you have more than one user who wants access, you can create as many authorized users as you wish by repeating the instructions starting at the Add button. P.S. It is nice to see I am not the only OS/2 user left... :) Rick Widmer Internet Marketing Specialists http://www.developersdesk.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Do you get the line number and filename of the script that *called* the
query function, or is it always the query function itself.
This is the sticking point for the original poster.
I get the line and file of the include file. Also, note that the $'s
should not be in there, I just removed them from the latest version of
the include file too, as it doesn't help much.
The idea of being able to get the line and file name info of where a
function was called from has come up on the developers list a couple of
times, and I'd love to see it happen, but it was shot down, and I'm
pretty sure it won't happen. The only way to do it would be like:
function Query( $Query, $Line, $File ) {
..
}
and call it like:
Query( $SomeQuery, __LINE__, __FILE__ );

Re: [PHP] Apache on Linux vs. IIS on W2K
Addressed to: [EMAIL PROTECTED] [EMAIL PROTECTED] ** Reply to note from [EMAIL PROTECTED] Sat, 17 Feb 2001 14:22:54 - So the question is, why is this acting like this? (When I meet "pro" they say Apache, Linux e.g.. is the best, and curse the IIS and W2K, but at this time I would say it's a myth..) The round() problem is because of differences in your versions of PHP, but the fact of the matter is that the UNIX version of PHP is ahead of the WIndows version because it is easier to program on UNIX, and there are more people interested in programming for UNIX than Windows. Most main stream functions will work on both platforms but there are things like the DBM database that works on UNIX, but fails because of differences in the Windows platform. (See http://bugs.php.net/?id=8819) Then there is a new image library that breaks the 256 color barrier, that is only available on UNIX. Work is in progress (maybe done) on a PHP extension to call it, but unless someone ports the base library to Windows it will not be available on that platform. I know there are other things, these are just some that I've seen recently.

I'd imagine count(*) would be slower just as select * is slower. I agree, SELECT should always specify only the fields you want returned, but COUNT(*) is an optimization. From the MySQL manual: http://www.mysql.com/doc/G/r/Group_by_functions.html COUNT(*) is somewhat different in that it returns a count of the number of rows retrieved, whether or not they contain NULL values. COUNT(*) is optimized to return very quickly if the SELECT retrieves from one table, no other columns are retrieved, and there is no WHERE clause. For example SELECT COUNT(*) FROM TableName will not even look at the table, it can get the number of entries from the index, and return it almost instantly. If you used SELECT COUNT(SomeField) FROM TableName MySQL would have to scan the table to make sure none of the SomeField values were NULL, which would not be included in the count. This can take quite a bit more time.

Re: [PHP] Specific PHP/JSP questions

2) In JSPs, it is possible to do server-side page redirection, i.e.
"forward" a request from page A to page B, as if the user actually
requested page B. There is no browser involvement in the redirection; it is
complete on the server. In this scenario, there are two "page scopes", and
one "request scope". How is this server-side redirection done in PHP?
You might do something like:
pageA.php
-
?
if( user_realy_wants_page_b ) {
include( 'pageb.php' );
exit;
}
?
Page A starts here...
-
That all happens on the server, and does not require anything outside of page A
to implement.
3) In doing the server-side page redirection, variables can be added to a
"request" object, which embodies parameters related to a request. Page A
can add variables to the request object (perhaps values from an SQL
select), which page B can then retrieve and display. How is this done in PHP?
In the example above, any variables set in page A will be visible in page B when
it is included. The values must be set BEFORE the include() is hit.
5) On a JSP site, I typically arrange things such that a particular JSP (or
servlet) accepts requests, processes them and then forwards them to one of
a number of different pages, depending on the outcome of the processing.
This is in contrast to the alternative approach where one simply goes to a
page, which does some processing and then displays the contents of the
requested page. What is the typical way to achieving this "funnel all
requests to a single point and have it forward the correct response to the
user" paradigm?
?
switch ( $Desired_Action ) {
case 'PageA' :
include( 'pagea.php' );
break;
case 'PageB' :
include( 'pageb.php' );
break;
case 'PageC' :
include( 'pagec.php' );
break;
default:
include( 'defailt.php' );
break;
}
would be one possibility.

Does die() give you a line number? If not, just put it in there.
No, die() does not add to your message.
Here is how I solved the problem:
function Query( $Query ) {
global $ShowQueries;
$Result = mysql_query( $Query );
if( !$Result ) echo( mysql_error() .
" in Query at $__LINE__ in $__FILE__BR\n$QueryBR\n" );
elseif( $ShowQueries ) echo( "$QueryBR\n" );
return( $Result );
}
usage:
$Result = Query( "SELECT fielda, fieldb. fieldc, fieldd, fielde " .
" fieldf, fieldg, fieldh " .
"FROM Table1 " .
"LEFT JOIN Table2 USING( common_field ) " .
"WHERE condition1 = '$Value1' " .
" AND condition2 '$Value2' " .
"ORDER BY SortField " );
Every query I've written goes thru this function. A couple of things about this:
The queries jump out at you when you are looking at the source code.
When you have an error in a query you get the mysql_error() message and the
entire query printed just below it. I've found that quite handy for debugging.
Almost every one of my programs has
#$ShowQueries='on';
very near the top of the file. If I am not sure just what it is doing to the
database, I just un-comment this line and each query string is printed as it is
executed. I've used it enough that I just add the line in every program, or use
a template that includes it.

I'd really appreciate a clear statement whether to use better
$foo = array('bar' = 'boing');
doWhatSoEver($foo[bar]);
or
$foo = array('bar' = 'boing');
doWhatSoEver($foo['bar']);
I had heard someone on the list say that it's always best to use quotes,
for the same reason as XHTML, where every value MUST have quotes.
But honestly I've been using only NO-quotes all year and find it much
easier to read. And NEVER any problem!
Also makes it easier when you need to use an array variable inside a quoted
string:
print "Hello there $client[name]";
Several people have mentioned that this is a bad practice, but no one
has mentioned why...
There are two gotchas you have to look out for, that quotes will
prevent. First, if you are using some_word as an array index and
someone decides that it would be a good name for a built in function,
constant, or statement all of a sudden all of your programs will break.
Second, take one of your programs that uses some_word all over it, and
add:
define( 'some_word', 'something_else' );
into one of your include files, now life gets very interesting:
$X[ 'some_word' ] = 'foo';
$X[ 'something_else' ] = 'bar';
echo $X[ some_word ]; // prints bar
echo $X[ 'some_word' ]; // always works as expected.

Or you could do it the easy way in MySQL:

This requires IN and OUT to be type TIME.

will be: 8:14:30. Exists any function which do this. Tnanx.
If your MySQL fields are a datetime type (-MM-DD hh:mm:ss) then you can
convert them to seconds since epoch (Jan 1, 1970 at midnight) and then
calculate the difference and divide by a number to get appropriate units.
Below is a set of functions I wrote to do that. Before I get to that here's
a simpler solution:
// $time = "16:45:15";
$time_array = explode( ":", $time);
// $time[0] = 16, $time[1] = 45, $time[2] = 15
$time_since_midnight = $time[0] * 3600 + $time[1] * 60 + $time[2];
// Do this conversion for both times, subtract and convert units.
function get_mysql_to_epoch( $date )
{
list( $year, $month, $day, $hour, $minute, $second ) = split(
"([^0-9])", $date );
return date( "U", mktime( $hour, $minute, $second, $month, $day,
$year ) );
}
function get_elapsed_time( $time_start, $time_end, $units = "seconds",
$decimals = "2" )
{
$divider[years] = ( 60 * 60 * 24 * 365 );
$divider[months] = ( 60 * 60 * 24 * 365 / 12 );
$divider[weeks] = ( 60 * 60 * 24 / 7 );
$divider[days]= ( 60 * 60 * 24 );
$divider[hours] = ( 60 * 60 );
$divider[minutes] = ( 60 );
$divider[seconds] = 1;
$elapsed_time = ( ( get_mysql_to_epoch( $time_end ) -
get_mysql_to_epoch( $time_start ) )
/ $divider[$units] );
$elapsed_time = sprintf( "%0.{$decimals}f", $elapsed_time );
return $elapsed_time;

Addressed to: "Noah Spitzer-Williams" [EMAIL PROTECTED] [EMAIL PROTECTED] ** Reply to note from "Noah Spitzer-Williams" [EMAIL PROTECTED] Tue, 23 Jan 2001 10:09:22 -0500 Is there a way to remove all cookies so matter what path they were set as long as it was from me (ex. in my parent directory). i need this because i was screwing around with setting cookies in different paths but now i cant get rid of one. If you are using Netscape, go into Edit - Preferences - Advanced, and disable cookies. Save that change. Then go back in and re-enable them. There is a side effect, _all_ cookies will be deleted. or Exit Netscape. Find your cookies.txt file, and edit it with your favorite text editor. Be careful if you change the length of stuff, but I've had good luck removing individual cookies by delete line. I am sure there are equivalent operations for IE, but I can't tell you how to do them.

I see someone else has another suggestion that might be better, using
array_count(). You learn something new every day, which is why I watch
this list...
anyway, the thing I see in your code:
while(list($index, $value) = each($dice)){ // Changed from $Input to
^
$Output[$Value]++; }
^
$Value != $value
I know my use of caps or not in this example sucks. I usually always
use Caps On Each Word for my var names, but I am trying to switch to
what appears to be the php standard, lower case everywhere. Sorry
about that...

Re: [PHP] a text formating cpu question
Addressed to: Noel Akins [EMAIL PROTECTED] [EMAIL PROTECTED] ** Reply to note from Noel Akins [EMAIL PROTECTED] Thu, 18 Jan 2001 22:05:46 + Hello, Question 1: A long time ago, I started my first big project using php3 and MySQL that would return on a query a listing of info from the database that was displayed in the browser with nested tables. If a user really wanted to test the limits of the database, he/she could get back over 3000 lines. Being that html tables were being used to display the info, a large number of tables were being created, and would crash netscape. I pretty much shelved this project for this reason. I'm now working on a similar project that won't return so many lines, but I would like to be able to use something other than html tables to display the info in a neat manner. Is there any php related things I could use to format a list in a browser other than html tags? could someone point me in the right direction? PRE Or break up your table so there are many small tables rather than one big one. Breaking up the table is probably best. Pre text looks pretty uggly. Question 2: Is there a way for php to detect the cpu speed of a users computer? I don't think so.

What happens when more than one person updates the tables at nearly
the same time?
a - insert record 9
b - insert record 10
a - get max ID = 10
b - get max ID = 10
Something doesn't look right here
What you are looking for is mysql-insert-id()
Get the id generated from the previous INSERT operation
http://www.php.net/manual/en/html/function.mysql-insert-id.html
thanks for Jason:-) Lucky the ID is sequential. That was command I
was looking for. cheers Jack [EMAIL PROTECTED] "There is

No, it won't - it'll return every userID in the table.
If your userIDs are sequential, you can just select "MAX(userID)" instead
of userID.

Sorry, I think it should be like this:
$queryInsert = "insert into user values ('firstname','lastname','email')";
$resultinsert = mysql_query($queryInsert);
$UserIdLatest = mysql_insert_id(userId);
Is that correct?
Yes, that is the 'proper' way to find out the value of a auto_incremant
field. The SELECT MAX( userid ) method will work fine in testing, but
then you get to pull your hair out when it starts to fail under heavy
load.
You might have a bit of a problem with the values() clause of the
insert. That statement expects you to list all the entries in the
table, in the order they appear, unless you specify a list right after
the table name. I've given up on that syntax in favor of this one:
$QueryInsert = "INSERT INTO user SET " .
" firstname = '$FirstName', " .
" lastname = '$LastName', " .
" email = '$Email' );
It also works with update:
$QueryUpdate = "UPDATE user SET " .
" firstname = '$FirstName', " .
" lastname = '$LastName', " .
" email = '$Email' .
"WHERE userId = 1234 " );
I like the fact that you can list any fields in any order while leaving
out anything you want.

Re: [PHP] logging page views, which method is better????
Addressed to: "Dallas Kropka" [EMAIL PROTECTED] [EMAIL PROTECTED] ** Reply to note from "Dallas Kropka" [EMAIL PROTECTED] Sun, 14 Jan 2001 00:57:10 -0600 I have a large site, with several hundred pages its a product listing and shopping cart and I want to log my page views I receive an average of 3000 hits per minute. Is it better (faster) to log my views to a database table? or to a flat file? No need to re-invent the wheel, all accesses are already being logged. If you are using Apache, take a look at the access log. Every hit to the server is already logged there. I am not sure what the default location for the file is, but you can find it with locate access_log or by looking for the string Log in your httpd.conf file. I believe it may appear under either the AccessLog or CustomLog keywords. You might want to look at Webalizer, or a couple of other programs to analyze the contents. http://www.mrunix.net/webalizer/ There are others, but this is the one I use.

Re: [PHP] RTFM me to IIF file format creation...

I need to create files and reports for importation into QuickBooks,
but they need to be in the IIF file format that QuickBooks
supports where can I find information for creating these files?
The content of the iif files is defined in Quickbooks help. Look for
IIF or Data import. It differs for each type of data you are
transferring. You will have to look in help to get the definitions.
There is also info on the subject and example files on the quickbooks
web site. www.quickbooks.com, I think. Search on IIF, and maybe the
type of file you want to create.
From memory, not tested
You can provide several different types of data in a single file. The
file needs to start with a definition of the fields you are going to
present. These definition lines start with !. Each of your data lines
must have the exact same fields in the order you defined them in the !
lines. You don't have to provide all the possible values, but some
record types do have required fields that must be provided, and filled
in.
Each record is a number of values with "\t" between them. The record
ends with "\r\n". You must use double quotes so the tabs (\t) and
Dos/Windows style line breaks {\r\n) are converted to the proper
character values.
/from memory
Once you have reviewed Quickbooks help, and the web site, if you have
specific quesions on your file format, ask again. It is actually
pretty easy. The best way to verify your files during development is
to open them with a spreadsheet program. Also, you MUST backup the
quickbooks data before you try testing your upload. If it fails for
any reason, just restore, fix the problem and upload again. Don't feel
bad if you do this a couple dozen times before everything works.
