[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=$id and MAX(ifield) should return id=2, ifield=200 (but this doesn't work, of course) Many thanks, Richard
[PHP] FTP and security
My company, as a matter of policy, closes the ftp ports of the servers in the DMZ. However, I am not convinced that this is necessary, given the advent of very secure ftp servers. I would appreciate any comments on the security of an open ftp port. To relate this to php, I am ready to give up trying to make my system(scp ..); code work, because I will have to give the apache user more permissions than I am comfortable with. So, I am thinking fo using php's ftp commands instead. I see nowhere in the documentation however, if the ftp_connect can be done via the ssh transport mechanism. Or, is this unnecessary, and can I use ftp (with plain text user and password passed to ftp_login()) on port 21 without worrying about getting hacked? muchas gracias Rich
Re: [PHP] FTP and security
To relate this to php, I am ready to give up trying to make my system(scp ..); code work, because I will have to give the apache user more permissions than I am comfortable with. What exactly are the problems you're encountering using scp? I created an apache user, which I called apache, and made sure this user could connect to the remote servers and created rsa keys so no passwords would be necessary (so my system($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 Executing: ssh -v -x -o'FallBackToRsh no' -o'ClearAllForwardings yes' -n -l apache thor scp -v -r -p /home/web/testsite/cgi-bin 'apache@loki:/home/web/testsite' OpenSSH_3.1p1, SSH protocols 1.5/2.0, OpenSSL 0x0090602f debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Rhosts Authentication disabled, originating port will not be trusted. debug1: restore_uid debug1: ssh_connect: getuid 48 geteuid 0 anon 1 debug1: Connecting to thor [127.0.0.1] port 22. debug1: temporarily_use_uid: 48/48 (e=0) debug1: restore_uid debug1: temporarily_use_uid: 48/48 (e=0) debug1: restore_uid debug1: Connection established. debug1: read PEM private key done: type DSA debug1: read PEM private key done: type RSA debug1: identity file /home/apache/.ssh/identity type -1 debug1: identity file /home/apache/.ssh/id_rsa type 1 debug1: identity file /home/apache/.ssh/id_dsa type -1 debug1: Remote protocol version 1.99, remote software version OpenSSH_3.1p1 debug1: match: OpenSSH_3.1p1 pat OpenSSH* Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_3.1p1 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server-client aes128-cbc hmac-md5 none debug1: kex: client-server aes128-cbc hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: dh_gen_key: priv key bits set: 135/256 debug1: bits set: 1551/3191 debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host 'thor' is known and matches the RSA host key. debug1: Found key in /home/apache/.ssh/known_hosts:1 debug1: bits set: 1576/3191 debug1: ssh_rsa_verify: signature correct debug1: kex_derive_keys debug1: newkeys: mode 1 debug1: SSH2_MSG_NEWKEYS sent debug1: waiting for SSH2_MSG_NEWKEYS debug1: newkeys: mode 0 debug1: SSH2_MSG_NEWKEYS received debug1: done: ssh_kex2. debug1: send SSH2_MSG_SERVICE_REQUEST debug1: service_accept: ssh-userauth debug1: got SSH2_MSG_SERVICE_ACCEPT debug1: authentications that can continue: publickey,password,keyboard-interactive debug1: next auth method to try is publickey debug1: try privkey: /home/apache/.ssh/identity debug1: try pubkey: /home/apache/.ssh/id_rsa debug1: input_userauth_pk_ok: pkalg ssh-rsa blen 149 lastkey 0x8086d50 hint 1 debug1: read PEM private key done: type RSA debug1: ssh-userauth2 successful: method publickey debug1: fd 4 setting O_NONBLOCK debug1: channel 0: new [client-session] debug1: send channel open 0 debug1: Entering interactive session. debug1: ssh_session2_setup: id 0 debug1: Sending command: scp -v -r -p /home/web/testsite/cgi-bin apache@loki:/home/web/testsite debug1: channel request 0: exec debug1: channel 0: open confirm rwindow 0 rmax 32768 debug1: channel 0: read=0 rfd 4 len 0 debug1: channel 0: read failed debug1: channel 0: close_read debug1: channel 0: input open - drain debug1: channel 0: ibuf empty debug1: channel 0: send eof debug1: channel 0: input drain - closed There is more output, but as you can see the read of the src files failed and an empty ibuf is sent.

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? Well, if you're going to be using ftp-over-ssh, I don't see why you're not using scp directly instead. 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.

I have two questions: 1.

Is there any existing code for that or hints how I can do it? 2. I have allowed packets through my firewall destined for port 3306, the mysql server.

[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] 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? Has anyone encountered the same problem? Thanks, I'm stuck! Rich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Apache/PHP/Java problem
I have Apache 1.3.24, PHP 4.2.0, and Java2SDK installed and working. My
problem is, when I boot up and dispatch my phpTest.php script from my
browser
?php
// java.util.Date example
$formatter = new Java('java.text.SimpleDateFormat',
, dd, 'at' h:mm:ss a );
print br.$formatter-format(new Java('java.util.Date'));
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
/home/web/staging/rfox/www/phpTest.php3 on line 3
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.

The last post is using the MySQL JDBC from a Java Server Page in a servlet environment. I never tried to run this from Java imbedded in a PHP script.

[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 sessionsave_handler = files):
?php
function reg() {
$test = 13;
session_register(test);
echo in reg(), test=$testbr;
}
session_start();
reg();
echo test=$testbr;
?
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,

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 sessionsave_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

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

[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?

[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?

A bit late in replying - but what the hay (or is that hey??) oh well...
From my understanding of virtual functions (and it's been at least 3 to 4
years since I've done C++) is that a virtual function has basic
functionality and a pure virtual function has no, and can't have, and
code.
Please correct me if I'm wrong

[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
Rich
PS Can anyone point me to the most comprehensive OOP documentation for PHP?
