Hi.
I'm changing my website to one based on My-SQL which will help with
organization and searching etc. Hopefully, the code for all the pages will
be stored in the database too.
However, I cannot get PHP to parse / execute the code stored in the
database. The script
$query = mysql_query("SELECT * FROM pages", $link);
$result = mysql_fetch_array($query);
print $result['4'];
gets the content of the page (column 4 of the database) but displays
include("common/counter.php"); include("common/navbar.php");
to the screen instead of opening and including these two files in the
output.
Is there something I need to do to the result to make it executable? Might I
need a \n between the two lines of code?
I'm using Win 98, Apache 1.3.19, PHP 4.2.0 and MySQL but I'm not sure which
version! (fairly recent though)

eval ('?>'.$var.'<?php');
if you want to eval usual php scripts.
(We close the ?> then comes the content of the php script which also can
contain
html and then we reopen <?php again)
So if you have a file:
<?php
include('test.php');
?>
and you say
$var = "<?php include('test.php'); ?>";
you'll result in
...
eval("?><?php include('test.php'); ?><?php");
which will evaluate normally.

The security danger comes from someone calling things like
site_domain/page.php?var=url_encoded_code_here
which will then execute all the code...
Of course you can before getting the code from the database, clear the
var and later check for it's size...

The security shouldn't be a problem. The user will be taken to
www.whatever.com/index.php?page=thispage
index.php then searches for a record with name = thispage and then evaluates
the code stored in a different column of the database.
If the name isn't found, "This page cannot be found" is displayed and if
nothing is entered it goes to the homepage.
Thanks for your help guys!

Use eval ... although beware of the serious security implications.

Is there any way to emulate ASP.NET's smartNavigation trick? What it does it
to maintain control state and scroll position between postbacks, as well as
stopping the page from flickering when reloading. It makes a mostly static
page look very cool.
Anyone done this in PHP, or know how to use IFRAMEs to do it manually?
Cheers

other characters.
Couls someone please show me how to do this?

Hello,
Make sure that this dll you have is in the correct extension path AND
this dll is a valid version for your verson of PHP. This is usually the
main things that will cause the error you specified.
In your php.ini, check your extension_dir = and make sure it points to
your extensions path. I keep mine under my php directory, like so:
e:\apps\php\extensions
so my extension_dir = e:\apps\php\extensions
Then make sure that dll is in that path. But also make sure it is the
correct version for the version of PHP you are running.
Hope that helps!

Hello,
my installation was:
I used php4.2.0-installer.exe and after it I used php4.2.0-win32.zip (it is
the font) for extensions, because the php4.2.0-installer.exe didn't have the
extensions directory (directory of my php_oci8.dll).
I could not do the compilation of php4.2.0-win32.zip (fonts) because was
necessary ms visual c++
Can you help me with any idea?
Thanks in Advance

I'm trying to replace values within a string with a value looked up from a database. I
have a function that looks up the value in the database for me but I'm having trouble
passing the value to the function because of the backslashes, is there a way around
this?
Code:
$cntnt = eregi_replace("\[L=([a-zA-Z]+)]"."([a-zA-Z]+)\[EL]", "<a href=\"" .
fndLnk(\\1) . "\">\\2</a>", $cntnt);
fndLnk is the function and the error I receive is -
Warning: Unexpected character in input: '\' (ASCII=92) state=1
Thanks for any help

Hey guys,
OK I favor PHP so far above ASP however it doesnt seem like PHP can
handle an array of COM Objects.
Here's the scenario:
Within the 'Deal' object contains an array of 'Bonds'.
I want to access each bond by doing: $comDeal->Bonds->Item[$i];
( btw Item is part of the com object to access each)
However i get this error: Warning: PropGet() failed: Invalid number of
parameters
In ASP I can do:
comDeal.Bonds.Item(i) and it works fine
Any suggestions?
Thanks!

Hi,
I am using PHP 4.2.1 under Windows XP. I am having trouble getting
socket_select to work on a UDP socket. Here is my code:
//Create socket
$socket = socket_create(AF_INET, SOCK_DGRAM, 0);
if ($socket < 0)
echo "unable to create socket(".socket_strerror($socket);
else
echo "OK";
//enable broadcasts
socket_setopt($socket, SOL_SOCKET, SO_BROADCAST, 1);
//first, a UDP broadcast command goes out
//I have verified with EtherPeek that this is indeed going out
if (socket_sendto($socket,$packet,$size,0,$IPBroadcast,$TCPIQPort) !=
$size)
echo "failed";
else
echo "OK";
//now call socket_select repeatedly for five seconds
$endtime = Time() + 5;
while (Time() < $endtime) {
$r = array($socket);
if (socket_select($r, $w=null, $e=null, 0) > 0) {
echo "\n<P>readable";
if (socket_recvfrom($socket, $buffer, 2048, 0, $addr, $port))
echo "\n<P>$buffer";
}
}
I never see $socket being readable, i.e. a return value from
socket_select greater than 0. I also can see in EtherPeek that UDP
packets are being sent back to this socket in response to the
broadcast.
Any help would be appreciated.

Okay, mystery to me, when I installed PHP 4.2.1 on Apache 2.0.35, the track_vars
function, stopped working.
a simple command like, example :
file : default.php
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
<?
echo("$text");
?>
then I type in the address in ie6, like : http://127.0.0.1/default.php?text=this
but it doesn't show anything. it becomes a blank page instead of echoing out "this".
Now, I thought track_vars was set to "Off" but in php.ini, it stood that it always was
on.
So, now I'm stuck... I'm using the php4apache2.dll module, which I suppose may be the
problem, but I don't think they would have forgotten this function in that file.
Anyone got any idée's??? I kind of need that function to do multipages.

The php directive track_vars is deprecated and is always
on. You appear to be referring to the register_globals
directive though, which is a hot topic these days in the
world of PHP.
If register_globals = on, then $text will exist in your
example (register_globals will create it). Otherwise
it won't exist automagically but will be available in
$_GET and $HTTP_GET_VARS, as well as in $_REQUEST. Also,
extract() or import_request_variables() can create them
if you want.
Try this:
print $_GET['text'];
Read about predefined variables, superglobals, and
register_globals in the PHP manual.

Hi Johan,
The globals that PHP sets up have changed since since PHP 4.2.x
See: http://www.php.net/release_4_2_0.php
You can turn on register_globals in the php.ini file but it is
recommended to use the more secure $_GET['test'] type variables.

Patrick Lynch.

Hello,
I am using php 4.2.0 and apache 2.0 on win95. I am facing some problems with
xslt extension. Problem is that xslt processor is unable to find the xml and
xsl files.
Files are in the same directory as the php file and document_root is
e:\wwwroot\newsite.
So when I do something like:
//////////////////////////////
$proc = xslt_create();
xslt_process($proc, "ptable.xml", "ptable.xsl", "ptable.html");
////////////////////////////////
It tries to find file under some other directory:
///////////////////////////////////////////////////
Warning: Sablotron error on line none: cannot open file
'D:/WINDOWS/SYSTEM/inetsrv/ptable.xsl' in E:\web\newsite\transxml.php on
line 17
//////////////////////////////////////////////////////
But readfile("ptable.xml"); is able to read the file and display its
contents.
Then I changed file paths like this:
/////////////////////////////////////////////
xslt_process($proc, "\ptable.xml", "\ptable.xsl", "\ptable.html");
/////////////////////////////////////////////////
and it searched for files under d:\.
So, I copied both files under d:\ and transformation worked and ptable.html
was created.
But because I wanted these files to be in the original directory I changed
it like this:
/////////////////////////////////////////////////////////////////
$xml_file = stripslashes($_SERVER["DOCUMENT_ROOT"])."\ptable.xml";
$xsl_file = stripslashes($_SERVER["DOCUMENT_ROOT"])."\ptable.xsl";
$html_file = stripslashes($_SERVER["DOCUMENT_ROOT"])."\ptable.html";
echo $xml_file, "<br>";
echo $xsl_file, "<br>";
echo $html_file, "<br>";
$proc = xslt_create();
if (xslt_process($proc, $xml_file, $xsl_file, $html_file))
{
echo "File ptable.xml has been transformed using ptable.xsl";
echo "Contents of this file are:";
readfile("ptable.html");
}
else
{
echo "Some error occurred<br>";
echo "Error is: ", xslt_error($proc);
echo "<br>Error number is: ", xslt_errno($proc);
}
xslt_free($proc);
//////////////////////////////////////////////////////////////////
Result is:
//////////////////////////
E:\web\newsite\ptable.xml
E:\web\newsite\ptable.xsl
E:\web\newsite\ptable.html
Warning: Sablotron error on line 1: unknown encoding '' in
E:\web\newsite\transxml.php on line 22
Some error occured
Error is: unknown encoding ''
Error number is: 66
////////////////////////////
But there is no encoding problem etc. because it created output file when
files were copied to d:\ as mentioned above.
