[PHP] moving file from one server to another
hi, i have thttpd (a very light weight http server) running as an image server on one box, and users uploading images to another php/apache powered box. I need to let users upload to the regular LAMP box, but then copy the image over to the custom image server (which does not have php or any kind of cgi capability). I was considering using exec() and scp to do this, but thought i'd ask and see if anyone had any better suggestions? many thanks -- Nick Wilson http://performancing.com/user/1 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'd probably use rsync to copy the upload tree to the image server myself, without involving php at all. yes. i'd considered rsync but the file needs to be available on the image server immediately. scp'ing it should work, but of course imnow having fun with the apache user and try9ing to work out how to give it an ssh profile :) -- Nick Wilson http://performancing.com/user/1 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] exec returns no output?
hi all,
i've searched and racked my brains, checked config files and all sorts
but cannot work out why the following command would give me an empty
array (and certainly not actually perform the requested command...)
exec('scp -v -i /id_dsa file.txt [EMAIL PROTECTED]:/target/dir/', $argh);
print_r($argh);
I can only surmise there is some setting todo with ssh/scp that im
unaware of?
any ideas welcomed, thanks!

Re: [PHP] moving file from one server to another
* and then Tony Di Croce declared How about nfs mounting a directory from the image server to a directory on the lamp server. This way, the files are never really on the LAMP server... yeh, that had ocurred to me, and may be a good solution Tony. The only thing that worried me was not knowing (ie having to research..) whether that would cause any significant overhead on the image server. It's not like it's an under spec'd machine, but the point of course is to have as small a server load as possible -- so we dont need to start dropping aditioonal boxes in too soon. I run nfs at home and we make good use of it on the local network where the actual application is for shared files under the laod balancer, but this would be another data center entirely. It may be that it's a trivial thing, the reason ive not done it is Im just not 100% sure on it is all, whereas simply scp/sftp'ing files into the image server dir is about as simple as it gets right? -- Nick Wilson http://performancing.com/user/1 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Do you use generated keys without a password for logging in? Otherwise
exec()
is just going to sit there while the scp command waits for a password.
Tha'ts exactly what i think it's doing. The -i specifies an identity
file according to the man page for scp so i would have hoped that would
take care of it (as i cant work out how to generate an identity for the
apache user itself) but i guess it is doing exactly as you say..

Right, im with you. The keyfile is mine though, and i know i can ssh from this box to that without any problem. I've made a test script for htis and it's returning some very weird stuff now.

Could it be a permissions problem? your ~/.ssh folder should has to be nailed now permissions wise otherwise SSH will complain. Also the id_dsa file is usually only readable by the user and nothing else (e.g. mode 0600) I'd suggest you check permissions. Also I'd add a new key for this rather than user your own. If the apache process can read your private key this is quite a security risk I think you're on the right track Col. I did a whole bunch more searching and the one thing I kept hearing was that no matter what you try, you just cant get the webserver to exec the script as another user -- so even if im saying '[EMAIL PROTECTED]' in both parts of the scp command, it's still being exec'd as apache, and apache has no home, and no .ssh dir. i've tried putting the perms on that dsa file directly as the apache user and even putting it eleshwere in teh filesystem but nothing seems to work As i dont have the ssh2 ext on this setup, and have no desire to go messin with new extensions it looks like im going to have to go gthe nfs route on this problem unless anyone has done this before and knows an answer? thanks for the help! -- Nick Wilson http://performancing.com/user/1 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The program on the webserver will always be executed as the user that runs the webserver. The nick@ bit is purely the syntax used by the program in question, in this case scp.

Assuming you have root on the box in question, you could write a shell script that does what you need then run it from apache via the sudo command. Provided you configure /etc/sudoers to allow the apache user to run your script without a password, it should work. As it's only allowed to run that one script, it is also fairly secure. E.g. /usr/bin/transfer_image.sh: #!/bin/bash if [ -z $1 ]; then echo No input file. exit 1 fi scp $1 [EMAIL PROTECTED]:/var/www/images/ And then in apache: exec(sudo -u nick /usr/bin/transfer_image.sh $file); (obviously escape $file with the escape_shell_cmd() func.) /etc/sudoers should contain something like: apache ALL = (/usr/bin/transfer_image.sh) NOPASSWD: ALL That makes a lot of sense.

Is it important that the transfer happens immediately? If not then a better solution is to drop the images in a folder that is then transferred by a script cron'd by the user that has everything required to do the scp. To be frank, anything is better than giving the user that Apache runs as any more permissions than you have to. yes, im afraid it does need to be immediate.

The above code is probably being included, and probably being included

?php
$GLOBALS['foo'] = 'bar';
function foobar()
{
global $foo;

foobar();
?
Try that and let us know what happend.
No, it didn't work. It's odd, becuase it worked just fine in the
previous version, and this is a module, so that module is exactly the
same as the previous one -- ie i've not made any changes to do with
includes to it (just a few upgrades to form functions and stuff).
I have fixed the issue, but the mystery will probably have to remain as
there is a lot more to do in the upgrade :( In the end i just manually
set $GLOBALS as you suggested and did a search and replace on the var to
do $GLOBALS[var] instead of global var; do_stuff($var);
crap i know, but thanks for the response!

[PHP] mhash() without mhash library?
hi all,
can anyone tell me if it might be possible to do an mhash() without
actually having the mhash library installed? for various reasons it's
very impracticle to have a compiled version of php running on our
production servers and i'd really like to be able to use the alexa web
services.
here's the php snippet that wont work, just so you know what the aim
is..
function make_sig ( $secret_access_key, $service, $operation, $timestamp)
{
$sig = $service . $operation . $timestamp;
$hmac = mhash ( MHASH_SHA1, $sig, $secret_access_key );
$encoded_hmac = base64_encode ( $hmac );
return urlencode ( $encoded_hmac );

read this page: http://php.net/sha1 (and search for 'hmac')

I have this: [EMAIL PROTECTED] ls ads/ config.inc db.inc funcs.inc init.inc where ads/ is a whole huge set of scripts from an existing setup. ads/ was originally placed on its own domain as it's a version of phpadsnew and runs as a server all by itself.

Unfortunately that's pretty much the same thing we tried first on this.
Even with the include path set to include every directory that contains
a script we need to access, the same error happens.
also look into the magic constant __FILE__ and the functions dirname()
and realpath(). read the manual regard how to use 'include_path'
No, the ideal is to not touch the config.php file or any of the other
required files (otherwise we may just aswell write our own) so those
functions and the __FILE__ constant are not usable.
Unless i miss your point?

check directory permission, check the include_path is being set,
check the include path is actually correct (I take it you have a good

Good call on dir perms, but yes, they appear to be fine. I *think* i
have a good understanding of include_path but here's the error which
quotes the include path so you/others can tell me for sure:

I would say fix the config file so that it can figure out where everything
is regardless of whether your using a vhost or stuck in subdir of some other
vhost. but thats just me :-)
Ordinarily i'd agree. We want to be able to update this set of third

interact with it rather than hack the core code.
Hope that all makes sense!

The subdomains have their own db's but share tables for sessions and some other stuff with the main site.

I am foreach()ing through an array of ip addresses in a 'ban script' and

foreach($ips as $ip) {
preg_match(/$ip/, $_SERVER[REMOTE_ADDR]);
$ban = TRUE;

This is great, but if 127.0.0 were in the ban list (for example) it
would still produce a ban as it partially matches.
How can I alter the above so that only *exact* matches are banned?

Ahh.. an oversight. The script has been cobbled together from a previous
version that supported partial matches. I'd just missed the obvious,
thankyou ;-)
Despite this being the worst idea I've ever seen, combined with a true lack

how should file system paths be handled?
Should I use
fopen('a_path/relative_to/thescript.php');
or
fopen('/usr/var/www/absolute_file_path/thescript.php');
Im not only using this for fopen. So does php work relative to the
script being called or not?
Much thanks...

[PHP] Protecting Commercial PHP Scripts
Hello all, I was wondering if anyone might have suggestions or useful links on protecting commercial php scripts.

There's no way to protect the code from copying. The only way to do that is not to give no one the code, provide the service based on the code instead of the code itself. Dont waste your time looking for a solution for a lost battle. It's just an advice, of course.

[PHP] Creating a Sequence from Array

2 = array(8854, 393, 4947, 77, 3343),
3 = array(393, 33)
);
I need to create an array sequence from that that would look like this:
array (
'1:123',
'2:8854',
'3:393',
'1:345',
'2:393',
'3:33',
'1:454',
'2:4947',
'3:393',// notice this has started from the start again...
'1:123',// as has this..
'2:77',
etc etc
);
untill the last number of the largest array (number 2 in
the original array) have been used.
I do have some code to show you but im afraid ive been going at it all
the wrong way so im not sure it's of any use. (posted below) - Could
someone please help me out? im just not good enough to do this i
think... thanks very much indeed..
Nicks messed up code so far:
function rubbish_function($machines) {
while(count($machines) 1) {
for($i=0; $icount($machines); $i++) {
sequence[] = ($i+1) . ':' . rtrim($machines[$i][0]);
array_shift($machines[$i]);
}
if(empty($machines[$i])) {
array_shift($machines);
} else rubbish_function($machines);
}
return $sequence;

[PHP] Muti-Dimensional Array Help Please
hello all,
I have some text files in a directory that contain newline delimited IP
addresses. Here is what i would like to do with them, and what i have
achieved so far:
I read the files into a multi-dimensional array like: (pseudo code)
array(IP_blocks) = (
File_number[1] = array('ip1', 'ip2', 'ip3')
File_number[2] = array('ip1', 'ip2', 'ip3')
File_number[3] = array('ip1', 'ip2', 'ip3')
)
the ip files have variable numbers of ips, some have 5 ips, some 40
etc..
What i want to do is to run a loop through the whole thing doing a task
on each IP address. Easy so far right? - Well, where im stuck is that i
want to operate on them like this:
do_stuff(File_number[1][ip1])
do_stuff(File_number[2][ip1])
do_stuff(File_number[3][ip1])
do_stuff(File_number[1][ip2])
do_stuff(File_number[2][ip2])
do_stuff(File_number[3][ip2])
I cant even get that far LoL! but then there is the problem of what
happens when there is no IP left in an array? (its a short file of
ips..)? - I need to start that particular array back at the beggining
but continue the cycle (it doesnt matter that an ip is worked on more
than once..)
Here is the *actual* code I have so far:
##CODE
?php
/*
* Open the proxies dir and read all of the
* ips contained within each file into a mutidimensional
* array ($machines)
*/
$dir = dir('proxies');
while(FALSE !== ($file = $dir-read())) {
if($file != '.' $file != '..') {
$machines[$file] = file($dir-path . '/' .$file);
}
}
$dir-close();
foreach($machines as $machineId = $ips) {
// do stuff here
}
###END CODE
Im not really expecting anyone to be able to do my work for me but some
*guidance* regardig how to tackle this problem would be magnificent...
Thankyou..

Yes, it does matter, a *lot* ;-)
I have to hit each machine in order, choosing an IP from that machine

$max = ($max = count($ips) ? $max : count($ips));

for($i=0;$i$max;$i++) {
foreach($machines as $machineId = $ips) {
if(isset($ips[$i])) {
do_stuff($ips[$i]);
} else {
continue;

}
?
Would that work with what i said above? im afraid i've never got the

Re: [PHP] Muti-Dimensional Array Help Please
* and then Ed Lazor declared
It looks like you're hading in the right direction. You've grabbed an array
of each file. Then cycle through that array and read data from each file.
The fread function will allow you to pull data from each file line by line,
so you can store each line in an array. Using your idea of pseudo-code:
$data = array();
$i = 1;
foreach ( file ) {
$n = 1;
fp = fopen
while ($line = fread() ){
$data[$i][$n] = $line;
}
}
foreach ($data as $key = $line ) {
foreach ($line as $line_number = $ip) {
// do stuff
}
}
hehe, not sure i get it but im playing with it ;-) i need to see code in
action for my head to understand it. I did have one rather good though
though (i think): If i can create an array with all of the ips in order
like this
123.123.123.1 // 1st IP from machine 1
123.123.123.2 // 1st IP from machine 2
123.123.123.3 // 1st IP from machine 3
123.123.123.4 // 2nd IP from machine 1
123.123.123.5 // 2nd IP from machine 2
123.123.123.4 // 2nd IP from machine 3
etc...
then i would have *exactly* what the application needs. Does that make
the problem any easier?

[PHP] Help with Array Sorting Please
Hi, If you scroll up the list you'll see another thread of mine, this is related. The reason for a new thread is that i've made a lot of progress but the old was getting really confusing.. Here's the scoop: I have an array like this: 123 = 1 // each value may have few or many duplicate values 321 = 1 543 = 2 432 = 2 // like here, more 2's than 1's see? 566 = 2 568 = 2 999 = 3 878 = 3 444 = 3 Now, the keys are not the issue. What i would really like, is for that array, to end up like this: 123 = 1 543 = 2 999 = 3 321 = 1 432 = 2 878 = 3 123 = 1 566 = 2 and so on... The important point here is that it does not matter if a key is repeated in the resultant array, in fact, that's *good* as long as it starts from the beggining again when there are no more values = (for example) '1' With me? If it helps to understand, each key is an IP address, each value a Machine number - my job is to never hit the same machine 2x in a row or the same IP 2x in a row, but to cycle through all the IP's on each Machine like the example resultant array. Phew... that was tough to explain, hope it's not a brain twister to understand ;-) Many, many thanks.. -- Nick W -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

oookay... i think i understand the page, but how would i imlement that
$fp = fsockopen (proxy.server.net, 8080, $errno, $errstr, 30);
if (!$fp) {
echo $errstr ($errno)br\n;
} else {
fputs ($fp, OPTIONS * HTTP/1.0\r\nMax-Forwards: 0\r\n\r\n);
while (!feof($fp)) {
echo fgets ($fp,128);
}
fclose ($fp);
}
You should get something like:
HTTP/1.0 200 Ok
Date: Sun, 26 Sep 2004 20:48:46 GMT
Via: HTTP/1.1 proxy.server.net (Traffic-Server/4.0.18 [c s f ])
Allow: CONNECT, DELETE, GET, HEAD, OPTIONS, POST, PURGE, PUT, PUSH, TRACE
Content-Length: 0
Well, it connects great! However, i get errors back about * being a bad
url...?

[PHP] Loop within Loop help please
hi everyone,
I have a simplified bit of code below:
?php
foreach($someArray as $someVal) {
//do some stuff
}
?
What i'd like to do is have a count inside that loop that will trigger
some action every 20 iterations of the foreach. Like this:
?php
$count=0;
foreach($someArray as $someVal) {
if($count is divisible by 20 exactly) {
// do some stuff
}
//do some stuff
}
?
How might i do that?
Much thanks...

if($count is divisible by 20 exactly)
Can be written as
If ($count %20 == 0)
% is the modulus operator and works like the division
operator, only it returns the remainder instead of the
quotient.
Ahhh.. thankyou very much jesse, that's great!

I see lots of references to modulus, which works fantastic.. but how
abut just testing if its equal to 20, then there isnt that extra
arthmitc call.. this is just another way to do the same thing.. take
your pick.. unless someone can see a bad reason for this method.
$count = 0;
foreach . {
if($count == 20) {
.
$count = 0;
} else {
$count++;
}
}
That would be fine, but im afraid in my effort to make the example
simple i forgot to ad a line:
$count++; ;-)

Re: [PHP] Help with fwrite()
* and then John Nichel declared John Holmes wrote: You can't just remove part of a file like you remove part of a string. You'll need to read (eventually) the entire file and only write back what you want to keep. Now, you said this could be a very large file, so you don't want to read the whole thing into memory. That's smart, so maybe using a swap file would be handy? Read from file1, if it's a URL you want to keep, then write it to file2. rinse, lather, repeat and at the end rename file2 to file1. This way you're only reading one line at a time into memory. Is keeping this info in a db an option? Not a good one, no. I've tried to figure a schema for it but it's been a long time since i did db work ;-) Speed is key here, it's an app that uses the Google API to fetch relevant urls, then uses cURL to fetch the pages, and if the user wants, to POST to that page. A DB would be okay i think but filesystem calls are just faster aren't they? Where I fail on the DB schema is getting my head around the relationship between the data, here's roughly what i need to do if anyone is curious or might prod me in the right direction... Each user (must have an id,name clearly) can fetch as many urls as they wish, those urls get written to the db, then as each url is fetched from the db it is dealt with with php and deleted from the db. What if a user gets cut off from the script and a whole bunch of unwanted urls are in the db though? Should the db go like this? db_urls url_id | user_id | project_id | url db_user user_id | name | whatever db_project project_id | user_id Wow, now i've written it down it seems clearer ;) you guys reckon that's the right kind of schema (based on what you know from the above..)? Thanks John Holmes, that's seems pretty neat but i may have been mistaken, i did a test with 5000 urls (shouldnt get much more than that at any one time) and the memory usage wasnt so bad at all... -- Nick W -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

That structure looks good, but it really depends upon what dealt with by PHP means. Well, the url is fetched into a variable by cURL, i then do a whole bunch of stuff with that variable with regex and wotnot, then the user decides if they want to post to that url, or discard it. Either way, the result is the url is deleted from the db_url (and now i think more about it, written to db_url_done - or a flag put on db_url (that's better i think)) As for the user getting cut off with urls still in the DB... it shouldn't Yeah, i realized that the moment i sent the mail ;-) they should be able to pick up with a project right where they left off my thanks, always good to get your schema cheked out by more knowledgable folk -- Nick W -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Delete Line from File?
* and then John Holmes declared Whats the easiest/best way to do that with php? just replace the line with ''? Yes, basically. You have to read the file, replace the part you don't want with an empty string and then re-write the file. If the file is small and you're using file() to read it, you can just unset() the element you don't want, then join the array back together and write it. Great, it just seems a bit clumsy which was why i thought maybe i was looking at it the wrong way.. my thanks! -- Nick W -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Could be your web server buffering the output until the script finishes or something else on your connection doing the same. Some web browsers will not show content until everything is received. You could try using flush() to see if that helps. Ok, that makes sense, i was fairly certain that i wasnt mistaken in thinking it should woek the way i expected...

Much thanks... that's because it's all sent as 1 single big chunk of data. To get around this, you should set implicit_flush to 1 (it's in php.ini). Otherwise, you can also use the PHP ob_implicit_flush() to do this. Setting it to 1 will flush the output buffer everytime it's written to, if set to 0 it will do as normal, and buffer it all to send it together. ah... now that makes a lot of sense, ill check that out, much thx... -- Nick W -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
