[PHP] suEXEC and PHP
Hi,
Apache 1.3.24, PHP 4.2.2
I am running a php script which executes something like
system("scp -r -S ssh host1:/home/dir host2:/home");
The scp command executes as the apache user, in my case 'nobody'. This does
not work, as the ssh authentication is not set up for user 'nobody' nor
should it be. Setting a different user, as in "scp -r -S ssh
myuser@host1:/home/dir myuser@host2:/home" deosn't work, ssh still tries to
authenticate 'nobody'.
First I tried running apache as a different user, 'apache', after setting up
the rsa keys etc (ssh stuff) for 'apache'. The authentication then works but
there are issues of the 'apache' user having read/write permissions on the
directories host1:/home/dir and host2:/home. I thought that giving the
'apache' user permission to read/write these directories wasn't a very good
idea.
Now I am trying to use the apache suEXEC feature to do this, so that my php
script can run as a different user (eg. myuser) who has all the right
permissions and ssh configured. However, so far I have been unsccessful and
suspect that suEXEC will not work with PHP. Does anyone out there have
experience with this? Any advice would be appreciated.
tia,
Rich

[PHP] FTP and security
My company, as a matter of policy, closes the ftp ports of the servers in the DMZ.
However, I am not convinced that this is necessary, given the advent of very secure
ftp servers. I would appreciate any comments on the security of an open ftp port. To
relate this to php, I am ready to give up trying to make my
system("scp ..");
code work, because I will have to give the apache user more permissions than I am
comfortable with. So, I am thinking fo using php's ftp commands instead. I see nowhere
in the documentation however, if the ftp_connect can be done via the ssh transport
mechanism. Or, is this unnecessary, and can I use ftp (with plain text user and
password passed to ftp_login()) on port 21 without worrying about getting hacked?
muchas gracias

I created an apache user, which I called apache, and made sure this user
could connect to the remote servers and created rsa keys so no passwords
would be necessary (so my system($cmd) call would work). This is what
happens when I run scp:
bash-2.05a$ scp -pvr -S ssh apache@thor:/home/web/testsite/cgi-bin
apache@loki:/home/web/testsite

is the result when I run scp as user 'apache'.

I thought that if I create an ssh tunnel for ftp, I could use the php ftp
functions, they would actually be using ssh transparently.

[PHP] SELECTing a row by maximum value
Hi, What would be a query to select a single record from a number of records in a table, depending on which one has the biggest value in an integer field? e.g something like: MYTABLE id ifield 1100 2200 3150 SELECT * FROM MYTABLE WHERE id=$id and MAX(ifield) should return id=2, ifield=200 (but this doesn't work, of course) Many thanks, Richard
[PHP] Multidimensional arrays
Hi,
Given the array $array initialized by:
$query = "SELECT id,name FROM MYTABLE";
$result = mysql_query($query);
$nrows = mysql_num_rows($result);
for ($i=0; $i<$nrows; $i++) {
$arr = mysql_fetch_array($result);
$array[$i]['id'] = $arr['id'];
$array[$i]['name'] = $arr['name'];
}
I know I can have a similar 'for' loop to step through the array, from 0 to
count($array)
But I would like to do something more elegant, with a foreach loop. But I have been
unsuccessful as a foreach seems appropriate only with a single dimensional array. Can
someone suggest a more elegant solution? Thanks, Rich
P.S. yes, I am fairly new to PHP, less than 6 months. Probably my array loading method
could be improved also!

[PHP] Server-server file copy question
Hi, I am using PHP 4.4.2.. I need a function to copy a file from one server to another. The src/dst filenames are relative to the Document Root of the website, but I can build an absolute path name if necessary. I can't use ftp because the ftp ports are closed on these servers. I would like to use http or ssh for the file transfer. The application is that multiple files can be copied from website to website on our various servers. I have been looking around at mailing lists, etc but haven't found a function described which does a non-ftp inter-IP file copy, only client/server file uploads and ftp functions. TIA, Rich
[PHP] Polymorphism question
I am new to PHP but 10 years in C++
One of the cool/powerful things you can do in C++ is the following:
class DrawPlainDialog {
public:
...
virtual Draw(); // implementation draws a vanilla dialog box
};
class DrawStyleDialog : public DrawPlainDialog {
public:
...
virtual Draw(); // implementation draws better dialog
};
Somewhere in my code I have a function like:
void ShowGUI( DrawPlainDialog& dd ) {
dd.Draw();
}
ShowGUI can be called with any object that is derived from DrawPlainDialog,
obviously. Only code that calls ShowGUI must be changed when a new
implementation of DrawPlainDialog is used. This feature of C++ to have a
base class pointer (or reference) be able to access derived class
functionality is not something I've seen in any PHP documentation. Does it
exist, and if not is there a workaround for this highly desirable feature?
TIA

[PHP] Re: Polymorphism in PHP
That's right, the difference between C++ "pure virtual" and "virtual" is
that a virtual function has an implementation but pure virtual only defines
an interface.
But can we get back to my original PHP question: Can I do something like the
following in php:
class Base {
function Foo() { echo "Base"; }
}
class Derived1 extends Base {
function Foo() { echo "Derived1"; }
}
class Derived2 extends Base {
function Foo() { echo "Derived2"; }
}
function Example ( $objvar ) {
$objvar->Foo();
}
...
$obj1 = new Base();
$obj2 = new Derived1();
$obj3 = new Derived2();
Example($obj1);
Example($obj2);
Example($obj3);
I think what I am asking is, is there any concept of a virtual function in
PHP, with a virtual function table?

[PHP] Unexpected OOP behavior

I defined a class constructor, and this constructor was automatically called *again* on my instantiated object when the script ended! This runs counter to 1. what one would expect a constructor to do 2. what the PHP docs say, which is that any clean up of a class object must be handled explicitly Can anyone verify/explain this behavior?

[PHP] Apache/PHP/Java problem

phpinfo();
?>
I get an error message that the java .so is not found. I start apache from
rc.local. If I then run 'apachectl restart' then the script works fine and
the java .so is found. The specific error message is (the java libs are
pointed to from php.ini):
Fatal error: Unable to load Java Library
/usr/java/j2sdk1.4.0/jre/lib/i386/libjava.so, error: libjvm.so: cannot load
shared object file: No such file or directory in

Since rc.local is executed at the end of system init, I can't understand why
php can't find the java .so. As I said, upon Apache restart it works fine.
Any insight would be greatly appreciated.

[PHP] Compilation error
Hi, I am compiling PHP 4.2.0 on a RedHat 7.1 system with mnogosearch 3.2.3. I am running into a problem that I have not seen on my other RedHat systems with the same configuration (except Redhat 7.2 instead of 7.1), and that is that the link does not work because there are some symbols that are multiply defined. Specifically, ftp_login. The linker tells me that the symbol was first definied in mnogosearch-3.2.3/src/ftp.c, and also found in php-4.2.0/ext/ftp/ftp.c (the are other ftp_xx functions multiply defined also, e.g. ftp_close, ftp_list, same files). If I remove --ftp_enable from my config then there is no error. I cannot figure out how to have ftp support in PHP and mnogosearch also! This does not occur when building PHP on my other RedHat system, where both --enable-ftp and --with-mnogosearch=/usr/local/mnogosearch are used and the linker is happy. Can anyone give some advice?

[PHP] PHP, Java, and Apache
I am trying to sort out several technologies and how they fit together. The basic problem I want to solve is to be able to use BrowserHawk, a JavaBean by CyScape, from a PHP script. In researching how to do this (and there are several relevant articles written) I have come across several different options and do not know how to weigh the pros and cons to come with the right combination of configurations. I am running Apache Server 1.3.23, PHP 4.1.1, and Java 2 SDK 1.4.0 on a RedHat 7.0 system. 1. There appear to be two choices of configuring Java with PHP: (a) rebuild PHP with Java support (./configure --with-java ...) and (b) integrate PHP into a servlet environment. 2. Apparently (see http://www.intechra.net/bh/install.html) in order to accomplish 1.(a) I must use the dynamic loading method (--with-apxs) to build PHP, which means I must also rebuild Apache (./configure --enable-module=so --enable-module=SHARED_CORE) Question: why? If I am rebulding PHP with Java support then why does Apache care? 3. What exactly does 1.(b) mean? How does one integrate PHP into a servlet environment, and how does this affect the Apache configuration? Sure, Apache will spawn a servlet to execute a php script, and another servlet (a JVM) to execute the BrowserHawk Java Bean.. but is this better? Is it hard to configure the system like this? 4. I have also run across an article advocating installing PHP as an Apache DSO, a dynamically loadable module. wait a second I thought PHP already was by default a dynamically loadable module to Apache! This is very fuzzy to me. Any advice on sorting this out for this web technology newbie would be appreciated. For example, is there one preferred configuration (dare I say.. a standard?) for getting PHP, Java, and Apache working together?

Nice, huh? Now, next step is to test BrowserHawk. I do not have servlet
support on my Apache webserver, but according to the BrowserHawk README
file, and I quote
BrowserHawk4J can be used anywhere server-side Java(tm) is available,
including servlets, JavaServer Pages, server-side JavaScript, and even
stand-alone Java applications. The only requirement is a Java Virtual
Machine version 1.1.x or higher. Note that to use any of the extended
properties of BrowserHawk4J (as defined below), you must use the BH4J
bean from a servlet or JSP environment.
So, I take this to mean that as long as I do not try to get extended
properties, I should be able to use my current setup to use BrowserHawks
basic capabilities. Fine, for the first step. My php.ini looks like
[Java]
java.class.path =
/usr/local/lib/php/php_java.jar:/usr/local/BrowserHawk/lib/bhawk4j.jar:/usr/
local/BrowserHawk
java.home = /usr/java/j2sdk1.4.0
java.library = libjava.so
java.library.path = /usr/local/lib/php/extensions/no-debug-non-zts-20010901
extension_dir = /usr/local/lib/php/extensions/no-debug-non-zts-20010901
extension = libphp_java.so
and my CLASSPATH and LD_LIBRARY_PATH are
[root@centauri /root]# echo $CLASSPATH
/usr/local/BrowserHawk/lib/bhawk4j.jar:/usr/local/BrowserHawk
[root@centauri /root]# echo $LD_LIBRARY_PATH
/usr/java/j2sdk1.4.0/jre/lib/i386:/usr/java/j2sdk1.4.0/jre/lib/i386/server:/
usr/local/lib/php:/usr/local/BrowserHawk/lib
but, when I point my browser to
http://localhost/BrowserHawk/examples/showbrow-ssjs.html I get:
Browser Capabilities Test Page
The following is information on your web browser's capabilities
as detected by BrowserHawk4J using Netscape's Server-Side JavaScript
technology.
User agent: write(request.agent)
if (b == null) { Browser information was null. This should never happen. In
case of error, getBrowserInfo() throws a BrowserHawkException.
}
Has anyone else gotten BrowserHwk running under PHP using Java extension?
Any suggestions would be appreciated. As far as I can tell (as my java is
definitely working!) this should work.
Thanks,
Rich

Re: [PHP] PHP and Java
>From my experience getting Java to run w/ PHP and Apache on RedHat 7.0, you can try setting the LD_LIBRARY_PATH environment variable ( without which my Java would not run) set to the location of libjava.so, libjvm.so, and php_java.jar, in my case (without line feeds) LD_LIBRARY_PATH="/usr/java/j2sdk1.4.0/jre/lib/i386: /usr/java/j2sdk1.4.0/jre/lib/i386/server:/usr/local/lib/php" Rich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] PHP and Java
Minor point, but you do mean LD_LIBRARY_PATH, not LD_LIBRARYPATH right? Also, set [Java] extension = libphp_java.so extension_dir = (pathname to libphp_java.so) Rich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Session variable scope - surprise!
This is a behavior I have not found documented, in fact the books I have read indicated that this would not be the case... given the script (with session.save_handler = files): "; } session_start(); reg(); echo "test=<$test>"; ?> The output is: in reg(), test=<13> test=<> I was quite surprised, but at least now I know why my code isn't working. I assume that $test is going out of scope after the function reg() exits. BUT, isn't registering a variable as a session variable supposed to give it "superglobal" status? I thought so. Can someone give me the 'official' explanation of this behavior? Many thanks, Richard -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Session variable scope - surprise!
OK, but then how do you explain:
";
}
global $HTTP_SESSION_VARS;
session_start();
reg();
if (session_is_registered("test")) {
$tt = $HTTP_SESSION_VARS["test"];
echo "session variable test=<$tt>";
}
else
echo "You really don't know what you're doing, do you?";
?>
This still gives me the output:
in reg(), test=<13>
session variable test=<>
Aaargh!

RE: [PHP] Session variable scope - surprise!
Then, when
session_register("");
is called (even on a variable which is going out of scope) what actually
happens? Where is the data actually stored? I know it isn't in the file yet
(I have session.save_handler = files) because nothing is written to the file
until the script exits. So the memory for should either be in free
store or on the stack. And, the second question: how can this memory, and
the data it contains, be accessed later in the script (after the
session_register) without having to depend on the original variable being
global or not?
Indeed, it appears that unless the registered variable is global,
session_register will not work. (Reference my test script appended below,
which can be loaded multiple times with no effect) This is undocumented!
Note: I am not complaining about documentation, I am just trying to
understand what exactly is happening when you register a session variable.

[PHP] PHP and Java Servlets
I have to build a "bridge page" from my PHP script that does the following: 1. Kick off a Java servlet (in my case running on my Tomcat4 plug-in to Apache) 2. Receive data back from that servlet and continue my PHP script. Does anyone have hard won advice, tips on great articles, examples, etc? TIA, Rich
