[PHP] syntax question
I'm looking through some existing code for a project I'm working on, but
I keep running into this syntax that I really don't understand. Here's
an example:
$a=strpos($a,'-')?explode('-',$a,2):array($a);
What do the ? and the : do here? I'm seeing this sort of thing all over
and just have no idea what ? : do. Thanks.

file_exists() function is quite slow.
in your case, better do fopen() to check if the file exist,
because you gonna do fopen() anyway if the file exist.
if fopen() return error, then you can assume the file does not exist.
dont forget to add "@" in front of the function name, to surpress err

you don't need regex to do that.
just insert add "(" to the beginning of $phone,
add ") " to the 4th position,
and "-" to the 4th position from behind,
using substr_replace() function.
anyway if you insist on using regex:
preg_replace("/(\d{3})(\d{3})(\d{4})/", "(\\1) \\2-\\3", $arr);

the nrcpts=0 in your log message might be stands for "number of

I might be wrong, but i think PHP's mysql_insert_id() must be using MySQL's API function call. Meaning, it will return whatever value MySQL return. Or in other word, mysql_insert_id() and last_insert_id() will return the same result. I have look thru the manual link above, and i think the phrase "immediately after" in the manual is more to advise the user to do mysql_insert_id() immediately after the INSERT query, because last_insert_id value might get overwritten by the newest one. the "immediately after" phares in the manual doesn't mean that PHP's mysql_insert_id() function is somehow tied to the previous/last INSERT query, so that if the INSERT fails then mysql_insert_id() will intelegently return the correct value. just my 1 cent -- Jimmy The average woman would rather have beauty than brains, because the average man can see better than he can think. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

> the webmaster will be notified please continue?
you can make a generic function to be called when such error occured.
the fucntion will print a nice/default error msg to user and you can
log detail information regarding the error into logfile or DB,
or even send out a notification email to you.
function fatal_error($msg, $file, $line) {
//$msg : the to be logged
//$file: name of file which trigger the error
//$line: line number which trigger the error
}
the usage:
include('');
@mysql_query or fatal_error (mysql_error(), __FILE__, __LINE__);
__FILE__ and __LINE__ are php predefined constant to indicate current
file and line number which is being parsed/executed.
you always have to pass this __FILE__ and __LINE__ because PHP dont
have the ability to "backtrack" from which file/line a function is
called :(
and dont forget to add "@" sign in front of the PHP's function,
to surpress the error msg generated by PHP.

using $REMOTE_ADDR directly is fine as long as the

otherwise, it's wiser to use getenv('REMOTE_ADDR') instead of

[PHP] strange behaviour of mysql_pconnect()
Hi list, I do a small test on mysql_connect() and mysql_pconnect(), and discover a strange behaviour. the output if using mysql_connect(): Resource id #1 Resource id #1 (both resource id are the same, as expected) the output if using mysql_pconnect(): Resource id #1 Resource id #2 (both resource id are different) at first I though pconnect() will create 2 different connection because the printed resource id is different. But after doing some test (by looking at the mysql processlist) i can conclude that those two link_identifier are actually the same (only one link, but with two different id) the question is, why pconnect() print different resource id, whereas connect() print the same one? -- Jimmy You can't quicken the growing of a plant by pulling the leaves -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

I come across this testing when discussing about how many same persistent connection can be opened to mysql. I believe there will always be exactly only one same connection (same connection = same host and same username), regardless of using connect() or pconnect(). but then someone make a small testing, by doing 2 same pconnect() and printing the returned link_identifier, which surprisingly return 2 different id. -- Jimmy There is no greater waste as a waste of time -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
[PHP] php printer functions...
I'm running PHP 4.1.1 on a Win2K box. If I understand the manual correctly, the printer functions have been integrated into PHP as of v4.0.4.

1.4.0 was hacked, but just for fun on tuesday, on wednesday I upgraded to 1.4.2 and it was hacked by another hacker in the night!!! I looked at the 1.4.2 for my customization, and this morning at the 1.4.4 and saw that even basic security holes are not fixed. The project team is working on the 2.0 so I think the release is not serious. I spent all the day to recover the defaced topics and texts, now I gonna backup and think to another solution...

Re: [PHP] update query based on array
not real sure of the setup of the form but if you have mutiple groups of
items to be updated then you should make the rank an array -- rank[pid#]
you should make all the items -- that are related part of the same group

[PHP] uploading + downloading Large files ...
Hi! My users need to upload and download large files (100 + megs). Right now I only allow 100k to be uploaded. Will I need to do anything to php/apache to make sure things continue to be reliable? My google search only found threads with bad endings and they had much smaller files. Should i just make em use ftp or scp? The problem with using one of those protocols is that it makes it difficult for the users to link the files to the proper account/relation/incident and anything that is a problem for users is usually a problem for me.

[PHP] cookies with internet explorer on macs
Hi!
The cookies i set for people using Internet Explorer on mac (OS X or mac

last for a few hours or sometimes even a few minutes, the time on the
end users computers are set correctly. IE on windows is fine and Mozilla

This is what I use to set the cookie.
$rand = md5(uniqid(rand()));
setcookie("sessid", $rand, time()+43200, "/");
Any ideas?

[PHP] STDIN/STDOUT in PHP
I've been looking for a way to work with stdin/stdout for a mod_rewrite's
rewritemap.
There's a working example in Perl, (just returning the input)
#!/usr/bin/perl
$| = 1;
while () {
print $_;
}
I've been trying to achieve this with fopen() read and write the
php://stdin & php://stdout .
#!/usr/local/bin/php -q
But no success.
In the apache man they say
Avoid one common mistake: never do buffered I/O on stdout! This will cause
a deadloop!
Hence the ``$|=1'' in the above example
Could sommone give some pointers how I could achieve the perl script above
in php?
TIA
Jim.

If passed to your function, $parameter2 will be your object (or
string or whatever you wanted), if not passed in it'll be null.
this might work this is an ugly solution from the top of my head, not tested:
$myObject =& (ifYour object exists)? $yourObject : new stdClass;

[PHP] mysql_fetch_row() and mysql_fetch_array()?
Yo!
I am wondering what the difference is between mysql_fetch_array and mysql_fetch_row. I
tried using this code:
$result = query("SELECT * FROM index1");
while ($row = mysql_fetch_row($result)) {...
but $row[] does not contain any data, but when I changed it to:
$row = mysql_fetch_array($result) ... it worked just fine.
So what is the difference?

[PHP] Please help!! how to compare an array with another
Shu!
I am currently working on a site where I want to randomly show pictures. I am using
sessions to save the id's of the pictures that a user has seen during his/hers visit.
My first question is: Can I use an array as a session variable? like this:
$arr = array(1, 2, 3, 4, 5);
session_start();
session_register("arr");
This array is to be passed on as an argument to a function used to find a random id,
that has not yet been seen. This array should be compared to another array with the
picture id's. There is two functions to accomplish the following: Create a randomized
array consisting of all the pictures id. Find one id in that randomized array that
does not exist in the array of allready seen pictures. These are the functions:
function show_pic($pics_voted, $cat, $sex) {
srand ((double) microtime() * 100);
$result = query("SELECT id FROM $cat WHERE sex='$sex'");
while ($row = mysql_fetch_row($result)) {
$arr[] = $row[0];
}
shuffle($arr);
$picture_id = find_id($pics_voted, $arr);
echo "picture_id => $picture_id";
return $picture_id;
}//show_pic
//Hitta id som inte finns bland $pics_voted[]
function find_id($pics_voted, $random, $x = 0) {
for ($i = 0; $i < count($pics_voted); $i++) {
if ($random[$x] == $pics_voted[$i] AND $x >= count($random)) return "no_pics"; //If
current key in $random[] is equal to current key in $pics_voted[] AND $x is greater
than, or equal to the number of keys in $random[], that is if the last key in
$random[] has been reached, return "no_pics"
elseif ($random[$x] == $pics_voted[$i]) {
find_id($pics_voted, $random, $x+1); //If current key in $random[] is equal to
current key in $pics_voted[] run the function again, with $x+1 as an argument to be
used in the $random[] array, that is: do the funtion again with the next key in
$random[]
}//elseif
}//for
return $random[$x];
}//find_id
Does anyone know why this ain't working? I get the same id over and over again. Maybe
there is an easuer way to achive what I want?
Please help!!
[PHP] Function to compare an array with another array
Shu! I need some help here. I have a script where I want to compare two arrays with eachother, and return one value from that does not exists in both arrays. I have an array of pictures id number created from a database query. I use sessions to save id numbers of pictures into an array.

[PHP] Newline in a guestbook
Hey guys! I'm writing a guestbook with mysql. My probblem is that when user enter at long word like blablablablablablablablablablablabla my html-tables gets screwed up. If someone is just fooling around the whole page design can be destroyed. I want to know how I can make sure that no word is longer than x characters. If a word should be longer than that, I would like the word divided into smaller parts with a - character at the end of the first word like this: "this is a text in the guestbook. if there is a really long word like blablablablablablablabla- blablabla it is divided into smaller parts and a - char is added to the first word." I thought about reading the whole message into an array, and then loop through it and for each word check whether it is larger than x chars, and if so, change it. But couldn't that be a very memory consuming script if it should do that for every message? Anyone knows how I could do this?

Hi, I'm trying to get the PUT method working on a Apache server running PHP as module. Theese are the steps I've taken so far: - I see in my apache logs that I've got PUT requests "PUT /path/filename.html HTTP/1.1" OK - I've added Script PUT /put.php , And checked so that the requests are beeing transfered to this function. OK - I've tried to get the ENV VARS but none show more than the PATH_TRANSLATED (and it's beeing set) OK - Checked the vars $PHP_UPLOADED_FILE_NAME and $PHP_PUT_FILENAME But neither are being set to any tmpfile NOT OK! - Checked $HTTP_RAW_POST_DATA , not set either. Would'nt it be better to have the PUT valuables in the superglobal $_FILES ? Or at least in a $HTTP_PUT_FILE var. If someone could direct me to where I can fine the temporary file, I would be much obliged! Theres bugs referring to this as an "non working" function is this so? - Bug #10383 Receiving an HTTP PUT, rather than sending one - Bug #14298 PUT absent $PHP_PUT_FILENAME $PHP_UPLOADED_FILE_NAME I propose a solution like the following: $HTTP_PUT_FILE['request_uri'] Path of the proposed upload like /mytest/filename.htm $HTTP_PUT_FILE['path_translated'] The full path of the proposed upload like /usr/home/foo/bar/public_html/mytest/filename.htm $HTTP_PUT_FILE['size'] The size, in bytes, of the uploaded file. $HTTP_PUT_FILE['tmp_name'] Temp name something like /tmp/hfdhjfufd8733 My only bad is that I cant program in C otherwise I would have been there doing it already. / Jimmy -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Sane path? Avoiding people climbing in directory structure ../../
Hi,
I'm planning on using userinput as a part of path to read (horrific I know :)
So to make this userinput a bit more secure I'm thinking to use
$path = escapeshellarg($path);
$path = str_replace("../","",$path);
I'm thinking to use a basedir in a constant something like
/usr/home/userdir (this also being set in php.ini)
then add the userinput and then append that to the constant and then use
opendir() on it.
I want to avoid people putting in nice little strings like ../../../etc/
Any other pointers?
/ Jim
Security is a state of mind not a sales arguement!

[PHP] Mcrypt: Blowfish or Twofish or no fish?
Hi, started playing with Mcrypt and just wanted to ask which encryption method makes the stronger encryption? (I can supply the necesary keylength). Should I go for MCRYPT_BLOWFISH or MCRYPT_TWOFISH? Or no fish at all :) So what do I need it for? I'm going to use it encrypting files, sizes varies between some 100 k's and 4-5 mb's. / Jim Paranoia + A system w/o users = Safe system :) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Mcrypt: Blowfish or Twofish or no fish? Part 2
Thanx for the suggestions! Someone mentioned that I could use MD5 and then encrypt the hash, how would I ever decrypt that? Is'nt MD5 a 1-way thing only? Another question? Should I go for bigger keylength or bigger blocksize or both? What makes for the best encryption? / Jim (and before someone suggest that I read the book Applied cryptography it's already orderd and on it's way :-) ) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] (Unlink(file) == rm file) ? (ignore this mail):(explain diffs);
Hi, (Unlink(file) == rm file) ? (ignore this mail):(explain diffs); Does PHP unlink function handle deletion of files equally as the "rm" command on the system in my case FreeBSD. Or does it involve caching/handling files in any different way? / Jim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
