[PHP] simple DOM/XML test fails in php
I have a very simple DOM test set up which is failing. Environment is
apacie 1.3.x, WIN xp, PHP 5.1.2 ; DOM seetings outlined in phpinfo()
indicate various DOM/XML support is enabled.
Failing php is:
?php
$dom = new DOMDocument('1.0', 'iso-8859-1');
echo $dom-saveXML();
?
which results in:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then
click the Refresh button, or try again later.
XML document must have a top level element. Error processing resource
'http://127.0.0.1/domtest.php'.

Re: [PHP] input validation?
I need to check that user input text is less than 300 characters
long. How?
if (strlen($_POST['input']) 300) { ...
You may want to also apply trim() to the input text to get rid of
extraneous white space at the beginning and end of the input.

Re: [PHP] Forum
Does anyone of you know of a good forum that is easy to customize and supports sticky notes, user registration, bb code and stuff like that?

I have a project where I'm being forced to do some ASP.NET development, which I've never touched. I need to learn it fast. Nobody has enough money to make me do ASP again. ASP.NET is leaps and bounds better than ASP. I would never use ASP but do do the occasional ASP.NET job (although PHP is my primary and preferred language). I'm not sure about learning ASP.NET fast, but you should start by: - Picking a language to use. VB Script and C# are the biggies. IMHO VB Script is easier, C# is better. - Picking an IDE. WebMatrix is free and easy to use. Visual Studio .NET is expensive and not easy to use but potent. - Knowing what database you'll be using. Probably Access (which totally sucks) or SQL Server (which kind of sucks). Other than that, I personally always start with a good book. If you do that, pick a book that uses the same language and IDE that you'll be using. Also, in my opinion, having a good knowledge of how to create a dynamic Web site helps when going from PHP to ASP.NET. If you know what the program must do in terms of functionality, protocol, etc., then it's mostly a matter of picking up the right syntax. I found that ASP.NET is the opposite of PHP: doing something simple is ridiculously hard but doing something kind of complex is pretty simple. All the built in widgets and wizards help and the form validation tools are really nice.

Re: [PHP] Fixing ID's in mySQL Table
Is there a way to fix ID sequence in a MySQL table using PHP? Basically I have some tables with a lot of records, 1000 to 5000. ‘ID’ is the Primary Key column in these tables, and at the time the code was originally written, there weren’t much verification of data being input going on. Thus a lot of junk records were being let in, which had to be deleted at some point or another. Now the ID sequence is all screwed up. It’s not in sequence anymore. You may not like this answer but you shouldn't fix this. Primary keys, by definition, should never change. Their purpose is to uniquely refer to a record. If you change the primary key of a record, then you've undermined this purpose. If you have holes in your sequencing, this isn't a problem either, as how the records are stored in the database is completely meaningless. If you need the records to be listed in some sort of order, you should add another column or table that manages that. But leave the primary key alone.

Re: [PHP] No forums?
One of the fallacies in your argument is that the lack of an official forum on php.net implies such distaste for message boards. I don't have a big screen TV but I have anything but distaste for them! Well, let me give you a different example. I don't have a TV at all, even though I could buy one. Knowing this, would you assume that I don't like watching it? No, I wouldn't, as my point is that the lack of something doesn't imply _any_one_thing_. There are many reasons why something may or may not exist. Assuming that there is such distaste for message boards is fallacious (as would be my assuming you don't like TV). The same thing with forum. It's a usual feature, just like website is. Would you be surprised if PHP had no website? Yes, I would, particularly as I've been going to it for years. Finding out that PHP had no website would definitely mess with my perception of reality. But I disagree with your theory that having a forum is implied by the technology. PHP is open source, so the fact that ANYBODY freely supports it in any way is just plain nice. Also, you should realize that your question could be rephrased as Why hasn't someone else done all this extra work (creating and managing a forum) because I would prefer it? Are you saying that I'm the only PHP user that might like discussing things on a forum? I'm pretty sure I didn't say that but I'll have to check my notes. I'm saying that you seem to be incredulous over the lack of something which you think makes sense. But my point is that there can be any number of reasons why php.net does not have a forum so the lack need not be ironic. In fact, that lack may even make sense (at least to those that run the Web site). Besides, you're implying that maintaining forum is extra work, while maintaining mailing lists isn't. Extra work for extra users you can live without, eh? Eh? What? Well, it IS extra work. The mailing list exists and, many believe, work just fine. Doing more than what is currently being done is extra, right? Or more? I'm almost positive about that.

The use of $var['index'] or $var[index] ($_POST['from'], $_GET

To fix this, wrap the whole construct in curly braces:
mail($to, stripslashes($_POST[subject]), wordwrap($_POST

You only have to do this within other quotation marks and only if the

Re: [PHP] No forums?
AFAIK, there are no official forums for PHP. Considering the fact that PHP is a web development tool, such distaste for message boards is ironic at the least. So why exactly there aren't any forums on php.net? One of the fallacies in your argument is that the lack of an official forum on php.net implies such distaste for message boards.

Also, you should realize that your question could be rephrased as Why hasn't someone else done all this extra work (creating and managing a forum) because I would prefer it? The obvious answer, which someone else has already suggested, is that maybe others (or those in charge of php.net) don't feel the need. In any case, if you are sincerely interested in either a support Web forum or a legitimate answer to your question, you may have better luck if your inquiry were more I would appreciate it if... or has an official forum been considered? and less this system that you've been using for years sucks and this is why I'm right.

Re: [PHP] setcookie() is not my friend
I'm trying to setcookie('username',$username,15552000) but on
subsequent pages $_COOKIE('username') is always null.
I verified that I'm setting it before any other output is sent to
the browser. I verified that $username does have some valid
contents. I also verified that the browsers I'm testing are set to
allow all cookies. I do have a $username and a $_SESSION
['username'] that contain the same data.
Well, the stupid/obvious question is: are you checking $_COOKIE
('username') like you posted or $_COOKIE['username'], which is
syntactically correct?
Secondarily, have you set your browser to prompt you when a cookie is
sent and, if so, what happens?

Second, what you are asking is a Notepad question, it actually has __nothing__ to do with PHP. Third, Notepad is a very bare bones text editor and does not have features like the one you're looking for. Fourth, a great way to see what an application can do is open it and look at the menus. Like File. Like FileOpen. Fifth, yes, Notepad can open remote files if you can connect to the remote server from your computer. This is true of any application. Sixth, can __you__ actually connect to your remote server from Windows so that you can open a networked file? Um, I'm guessing not. Seventh, many FTP applications let you set an external text editor. This would let you connect to the server, edit a file in Notepad, and save it, without saving it to your hard drive first. Eighth, many of these answers will be the same for Dreamweaver, although that's a much more sophisticated application. That being said, DW probably has the ability to open and edit remote files.

Re: [PHP] OT Re: [PHP] can I compile php source
While Yes may be a technically accurate answer to a question like Can I ... or Can anyone ..., a couple of points must be acknowledged: 1) Such an answer doesn't help the original poster. Period. And the purpose of a resource like this is to help, right? Even a RTFM or search Google at least gives the user __something__ to work with (and the lesson there being that if they read the manual or search Google, they'll quickly find answers). If your argument for answering Yes is that you're teaching the user to ask questions the smart way, then why not answer their intended question AND refer them to the smart questions page? Do you honestly think people are learning __anything__ when you reply with a Yes? Moreover... 2) It's commonplace in human discourse to attempt to address the *intent* of a person's question rather than the literal question itself. If you were helping a friend re-shingle a roof and they said Can you hand me that hammer?, hopefully you would actually hand them the hammer, not say Yes. They are many colloquialisms in languages--like when someone says What's up?--and it's just obstinate not to recognize them as such and respond accordingly. Finally, if you don't agree that Yes isn't helpful and that it's an inappropriate answer anyway, how about this: such emails are a waste of resources. It's a waste of the time (.1 nanoseconds or whatever) it took you to write. It's a waste of bandwidth (at a few bits a pop). It's a waste of everyone's time in reading and deleting such emails (another second). And it tends to start a sequence of even longer, off topic threads such as this one. So, seriously, if you don't feel like helping or you don't believe that a message should be posted here because it's off topic or you don't believe that a question was phrased properly, wouldn't it be better for everyone if you just didn't respond?

I understand joins, etc for the query of the data, however adding the data - still getting my head wrapped around it (multiple tables). You'll need to run separate INSERT queries, I suspect.

Re: [PHP] Object oriented??
Is PHP an object oriented language. If not is it gonna be? PHP is not an object oriented language (like Java).

Re: [PHP] Object oriented??
Yes of course...but was confused since some says it is so and some says it is not...So thought of asking the pros.. It is. PHP4 had limited support for OOP, though it was quite usable. PHP5 goes further and provides pretty much everything else. See the documentation on php.net for the complete language reference. I guess this is where the OP's confusion stemmed from (Robert said Yes, I said No)! A liberal definition of OO is An adjective applied to any system or language that supports the use of objects, under which PHP would qualify. But, in strict OO languages, everything must be done using objects. You can't even do a simple Hello, World without them (I could be wrong on this, of course). With that understanding PHP would not be OO. So, in short, PHP __supports__ objects but does not __require__ them. There's a good chance that 20 people will chime in now, with their own corrections.

Re: [PHP] Mac OS X and Editor
Hi guys, I just like to ask those using Macs here as to what editor and/or IDE they are using for writing PHP codes. BBEdit is generally consider to be one of the best (note: I said one of the best, not best, so let's not start about how emacs, vi, and vim are better) text editors available on any platform. It's very easy to use yet powerful (supports grep, works with Xcode, has command line tools, etc). The new version 8 ties into Apache, letting you test PHP scripts in the application. It's a text editor, not an IDE, though. There are PHP- and SQL-specific libraries built in so that it recognizes function names and such.

Re: [PHP] Extra byte added to PDF streaming file
It appears as though some readers (such as adobe acrobat) can read this file fine yet others (such as the program gv in *NIX) cannot read it. The reason for this is that somehow a hex 0A is added before the inital %PDF-1.2 which marks the start of the PDF file causing some readers to not recognize it as a PDF file. Is there anything in this code which could possibly (always) cause an extra byte (0A) to be added before the real start of the file? And no, the file is not corrupted (I've already tried that) - this only happens when it goes through this script, and not loaded directly as example.com/file.pdf.

I forget the details and it depends upon your installation of Apache but you'll want to save your files in a location like C:\Apache\www. You can always check the Apache documentation for assistance on things like this but it should be a 'www' folder. Because when i do access the php scrips via URL (e.g. http://localhost/test.php) i get an error message saying the page does not exist. It is currenly saved in a regular folder away from apache.

Re: [PHP] Is Function Constants the Correct Term?
I have been experimenting with defining functions as constants. Below is what I am using to test Function Constants: pre ? define(LOGIN,user); define(PASS,pass); define(DB,mysql); define(DBLOGIN,dblogin(LOGIN,PASS,DB)); This is simply not allowed. see: http://php.net/define Can you elaborate on what is not allowed? Are you saying defining function constants are not allowed or are you saying redefining constants are not allowed? I believe the answer is that both concepts are not allowed. Constants, by their very definition, cannot be redefined (except for magic constants, which is a different thing). Also, constants must be set as scalar values. PHP doesn't support function-like macros as you might have seen in the C preprocessor. This is all in the PHP manual, under define() and constants.

Provided you can change the variable, you should be able to create a loop that sets all the variables to or some base values etc. Larry -Original Message- From: Andy B [mailto:[EMAIL PROTECTED] Sent: Sunday, April 04, 2004 6:03 PM To: [EMAIL PROTECTED] Subject: [PHP] $HTTP_SESSION_VARS still holds original values even after unset? how would you empty all the contents of $HTTP_SESSION_VARS when you dont need them anymore but still keep the current session running? the problem seems to be that when i try to fill them with something else (dont need the original values anymore) but need new ones without destroying the session itself they wont fill with new things. unset($HTTP_SESSION_VARS); does nothing to help at all because they still have the same values that they were originally filled with (and not to mention they are still in the session)... anybody have any ideas how to delete or empty out the array but keep the session active ?? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] passing variables
When using a link like xxx.proceed.php?language=gbr the 'proceed.php' script does not receive any $language variable. Does someone know how to get it run? This is a register_globals issue. Refer to $_GET['language'] instead of just language. Or, at the top of your script, add $language = $_GET['language']; and you shouldn't have to change anything else.

[PHP] multi-dim array from text file
Hi,
I need to do some text file manipulation of a text file from an html
interface. I have a file with multiple lines where each line has 2 fields
each (a mac address and an associated vlan). Here's an example of rht text
file:
/tmp/TEST:
a1b2.c3d4.e5cc VLAN3
a1b2.c3d4.e5dd VLAN4
a1b2.c3d4.e5ee IS
a1b2.c3d4.e5ff VLAN6
a1b2.c3d4.e5a1 VLAN7
a1b2.c3d4.e5b2 VLAN8
a1b2.c3d4.e5c3 Printer
a1b2.c3d4.e5d4 Guest
a1b2.c3d4.e5e5 IS
a1b2.c3d4.e5f6 VLAN6
a1b2.c3d4.e5a2 VLAN2
a1b2.c3d4.e5a3 VLAN4
Being an admin and not a developer of any kind, I'm having trouble reading
in the file and being able to output specific lines and fields of a php
array. This is what I have so far:
HTML
HEAD
TITLEMAC address Listing/TITLE
/HEAD
BODY
?php
$CnfRec=array();
$CnfRec=file(/tmp/TEST);
foreach ($CnfRec as $line) {
$CnfRec=explode( ,$line);
echo LINE: ;
print_r($line);
echo CnfRec: ;
print_r($CnfRec);
echo P;
};
?
/BODY
/HTML
What I want to eventually do is read in the records and fields of this
file, present it as a form, allow admins to modify the second field and
write that back to the text file (while backing up the original file).
As a reference, I handle it in a completely different way, but this is how
I'd kinds like things to look visually ( just one submit button would be
preferable):
==
HTML
HEAD
TITLEMAC address listing/TITLE
/HEAD
BODY

[PHP] scope problem
Apparently I'm having some kind of meltdown here. Can anyone explain the
logic behind why the following variable has the original value and how I can
pull/push the value to access it at the end?
while loop
{
$variable = 100;
while loop
{
switch($othervar)
{
case 1:
$variable = $variable + 100;
break;
case 2:
$variable = $variable + 200;
break;
case 3:
$variable = $variable + 300;
break;
}
echo $variable.br;
}
echo brThe final value is .$variable.br;
}
This gives values something to the tune of...
200
400
700
100
I usually have variables set outside of a while loop that increment based on
the contents of the loop and I could swear that they hold the value on the
other side of the loop. I don't usually use break; in my scripts unless I'm
using switch. However, I would think that if using break was throwing me,
that the value wouldn't print on each cycle of the loop.

Toby's solution still holds in this scenario. Actually exactly has you have

the concatenated string you made with the while loop and the second array[1]
holds the total number of result rows from your query.

Hi List,
I have a function that makes a call to mysql based on certain vars.
---example
Function MyFunc(){
if(isset($_POST[var])){
$sql = mysql_query(select * from table_name where field=\$_POST[var]\
); $returnsomething =blah blah; } return $returnsomething; }
And that all works fine no probs here but.
I want to use a result somewhere in my script that is not returned by
return. Let me show you...
---example
Function MyFunc(){
if(isset($_POST[var])){
$sql = mysql_query(select * from table_name where field=\$_POST[var]\
);
$num = mysql_num_rows($sql); // I want to use this result outside this
function.
$returnsomething =blah blah;
}
return $returnsomething;
}
So $num contains a number that I want to use outside the function which is
not covered by return.
I know return stops a script and returns what I want it to return but how do
I send out of the function the var I want.
I have tried $GLOBAL[var]=$num; but that dont work, but I thought I
would'nt anyway just tried it and yes I know I have to declare it inside my
new function using global $var; to use it.
So I ask is this achiveable or how can I do this.
Thank you in advance

Since putting .jpg solved the problem for me, I'm ok with that work around, but you're right. I'm using session_start() on all of my scripts.

Giving up sessions for one simple issue sounds a bit drastic. I'll dig up the header information I'm sending that the x.pdf addition helped me with and send them to you if you'd like.

RE: [PHP] Re: Session expiry issues in IE, still.
Interesting point. After all, to remove a cookie you simply give it an expire time in the past. However, it should only explain the lack of cookie receipt. Since the user is able to surf for a period of time on the site before getting the boot, I wouldn't think it would apply. In the last post it sounded like it is not at 5 min but rather expiring very speradically. I bet there is a particular page that is killing them. Perhaps one of the re-writes or something. I would take IE and start traversing the site to see if you can't localize it to one area when it happens.(or more in particular where you just came from when it dropped). Larry PS if you have a dev site to work on, and the session checks are in a header, try changing the header to display the session ID and watch it for a change while you surf it. -Original Message- From: Matthew Weier O'Phinney [mailto:[EMAIL PROTECTED] Sent: Monday, January 05, 2004 9:08 PM To: [EMAIL PROTECTED] Subject: [PHP] Re: Session expiry issues in IE, still. * Tarrant Costelloe [EMAIL PROTECTED]: I wrote to the list a couple of days ago about issues Planet-Tolkien.com members were experiencing with Internet Explorer, where their PHP based $_SESSION seemed to be expiring very speradically, where as Mozilla and Opera browsers this issue was not occuring and they would stay logged-in.

RE: [PHP] Submit Button Refresh Problem?
we need more code than ? makeArrays(); ?...
By the looks of that alone, it appears that you have that inserted into the
html somewhere around the submit button. If that is the case, the function
will run every time you load the page. You have to set a trigger to
determine whether it should run or not. For instance, the form in which the
submit button is in can have a variable such as input type=hidden
name=executeRand value=1 so that when you hit submit, that value is sent to
the target of the form, (which I take it is this same page). The code
around the function in php could be...
if($executeRand == 1){ makeArrays(); }
You'll need a second form around your other submit along with a variable for
it to send etc.
Hope that helps

Subject: [PHP] Submit Button Refresh Problem?
I have a php file that contains all the functions that I run on the page
that is displayed, self-contained.
The main function is ? makeArrays(); ?
I am invoking that function with a Submit button OnClick event.
Whenever I click the button, the page refreshes and the function runs just
fine displaying a dynamically generated random sequence of numbers.
The problem is the page refresh itself.
When the page first loads the function runs and it shouldn't, the display
should be blank until the button is clicked.
This is a problem because I have another button that will be coded to write
the data generated to a database, at present that function is empty, however
when I click that button the page refreshes again and the number data
changes.
How do I keep the page from refreshing on load and apparently self clicking
the form button, and how do I keep the page from refreshing and running the
'makearrays' function when I click the 'writedata' function? When the
'writedata' function is invoked from a button click only that function
should be called and the data from the previous page should be returned to
the page again (same).. i.e. the random number sequence does not change.
Thanks!

RE: [PHP] PHP, Server-Side?
You can create a soap server. I have one set up, the client side runs a
function which is translated into xml sent to the other server (in my case
over ssl) the other server translates to php, executes the function and
returns the results. You create the actual code for the function on the
server and give the client details on what the function does and what data
it requires. If you build both it is very easy. The client has no other
options but to run the function name while supplying the data. ex.
server...
function pullLatestReport($login,$password,$howfarback)
{
check db for authentication...
if auth correct to run this function run
do queries nec. for request return result.
else
return error
}
As you can see the server has total control over what gets executed, soap is
designed to be platform independant. .net, java etc. can be used as the
client. Of course that is only a added benefit since you are making both
ends.
I use nusoap which is all php and isn't too hard to figure out.

php-general,
I was wondering if it is possible with PHP to create a snippet of code
which could execute on one server but be stored of a different server?
Basic premise is to sell a product written in PHP which people could
include on their site but not be able to edit or see the code, maybe by
using some kind of include(), url() or snippet method?

How about this one? Add it to an include for the site and use it whenever
you have an error check.
function goBack($newSite,$errMsg)

$send = ;
foreach($_GET as $key=$value)
{
$send = $send..$key.=.$value;

$goTo = urlencode($newSite.?errMsg=.$errMsg.$send);
header(Location: $goTo);
die();
}
if(there is a problem with the data)
{
$errorMessage = some error;
goBack($HTTP_REFERER,$errorMessage);
}
I'd have to test the $HTTP_REFERER part, but I don't see why it wouldn't
work. I like the die() in there so I can just use an if statement at the
beginning without having to indent the rest of the script. Especially if
you have a lot of error checks.

Subject: [PHP] urlencoding.
Let me give a quick background. I am a very experienced programmer but
I haven't done much php and only a little web development in perl. I am
now creating a web site with Apache, php and MySQL.
I am having the user fill out a form and then save the data in MySQL.
Before I save the data I do a few checks and if there is a problem I do
a redirect back to the form and send all the data back so they don't
have to fill out the whole form again. Here is some sample code I use
to build my redirect url
$UserID = $_POST['UserID'];
$Password1 = $_POST['Password1'];
$Password2 = $_POST['Password2'];
$Email = $_POST['Email'];
$FName = $_POST['FName'];
$LName = $_POST['LName'];
do checking of data here.
if(there is a problem with the data){
$ErrorMsg = some error;
$redirectStr = $httpHost/CreateAccount.php?;
$redirectStr .= UserID= . urlencode(stripslashes($UserID));
$redirectStr .= Password= . urlencode(stripslashes($Password));
$redirectStr .= Email= . urlencode(stripslashes($Email));
$redirectStr .= FName= . urlencode(stripslashes($FName));
$redirectStr .= LName= . urlencode(stripslashes($LName));
$redirectStr .= ErrorMsg= . urlencode($ErrorMsg);
header(Location: $redirectStr);
exit;
}
My problem is that any field that contains a double quote, all data
after the first double quote is missing from the form field. When I
look at the long URL I do see a %22 where the are supposed to be, and
all other data is there too.
Any Ideas? If there is a better way to do this feel free to suggest a
change in my whole method here. Just as a note validation of the UserID
has to be done on the server side, to check for duplicates in the MySQL db.
I would also welcome insight on standard techniques to make sure the
user isn't trying to break the code by sending bogus data. I am already
checking that the data isn't longer than I am expecting.

RE: [PHP] Setting a 'life-time' clock to a displayed information
The timer on the client browser would have to be done in some client-side language. On the server side you can place any order information that is out with a supplier in a db field along with the time it was pulled. When the next supplier submits a request, the db is parsed for pending jobs whose time has gone over the 30 minutes. If it has, then provide the same information to this supplier and update the record to show who it is out with. If there are none that have gone over the 30 then generate a new set for this supplier and record the time it was provided and the supplier it was given to. When the supplier publishes the completed information, check to make sure it was in time, if it was in time remove the entry from the db so that it isn't given back out. If it is too late you can generate an error page and start back over if he still wants to try. Note there may be some additional steps necessary to make sure that two suppliers aren't trying get an expired entry at the same instance where there is a fraction of a second between checking the time on the record and taking the record where both check the time and take the same record. You will probably have to use locking on the db to avoid this.
