Some ftp server (like vsftpd) can be configure to change the mode of all
uploaded files . There is a possibility that your server is configure
to chmod your files (in vsftpd it is controlled by the file_open_mode
option in the config file)

It doesn't make sense to me that the function would work fine on a file and
not work on a directory. Moreover, why would the ftp_site chmod command
produce a working result and not the ftp_chmod? This seems strange to me.

If you are using php 5, don't forget about str_split, with 4 as the
second parameter.
http://us2.php.net/str_split
so you could do:
echo implode("<br />", str_split($string, 4));
if you still have php 4 or earlier, look at that page anyway as there
is a workaround function in the comments for earlier versions of php.

another good method is a "Live Linux CD". you can find a light weight
live linux distro and remaster it to include your live web site. so
your client can put boot his/her pc with this cd and start browsing
the site.
this way you can use whatever the LAMP combination!

Hi,
I have a regular expression check as:
preg_match("/$xyz/", $data, $matches);
And, as you know $xyz means "string starts with xyz". But somehow PHP
5 is interpreting this as variable xyz, and gives the notice below.
You can ignore the message, but now it matches everything that has
xyz, i.e. aaxyzbb
PHP Notice: Undefined variable: xyz in /tmp/test.php
Any idea about how I can specify "string starts with xyz" or fix it
such that PHP5 won't recognize this as a variable?
Thanks...

Either use single quotes:
preg_match('/$xyz/', $data, $matches);
or escape the $-sign:
preg_match("/\$xyz/", $data, $matches);

No it doesn't - "string starts with xyz" would be "/^xyz/" which
coincidentally avoids your problem of xyz being interpreted as a
variable name.
More generally, if you don't want $xyz interpreted as a variable, then
use single quotes - or if you must use double quotes, then escape the
$ with a backslash.

David,
I'm under pressure to permit AND, OR & NOT. My research group insists
that MySQL 4 syntax is "not good enough".
An idea of what one might enter is here (on the bottom):
http://compcanlit.usherbrooke.ca/advanced.html
I was hoping to get away with replacing " AND " with "+", " NOT " with
"-" and " OR " with " ".
I use this as SQL:
SELECT *,MATCH (YR,AU,ST,SD,SC,BT,BD,BC,AT,AD,AC,JR,KW,AUS,TUS,GEO,AN,SA,RB)
AGAINST ('$mydata->searchenquiry' IN BOOLEAN MODE)
AS relevancy FROM ccl_main
WHERE MATCH (YR,AU,ST,SD,SC,BT,BD,BC,AT,AD,AC,JR,KW,AUS,TUS,GEO,AN,SA,RB)
AGAINST ('$mydata->searchenquiry' IN BOOLEAN MODE)
ORDER BY relevancy DESC;-->

I think you have a slightly more complex situation than just replacing
text
between what I assume is a LIKE or multiple WHERE situation and a fulltext
search. Perhaps if you can give an idea of the type of string you are
likely to get in $searchenquiry, and to what you wish to convert it, we
might be better placed to give advice.
I can envisage that you might get 'bananas NOT pears AND apples' in the
variable; I guess you would currently manipulate that to a query such as
"WHERE x = 'bananas' AND x <> 'pears' AND x = 'apples'"
(OK that's not a good example) but if you were to feed that to a fulltext
search you might want
WHERE MATCH (x) AGAINST ('+bananas -pears -apples' IN BOOLEAN MODE)
or maybe something else depending on the version of Mysql and exactly what
you are trying to do with your fulltext search.

Please don't top-post [1]. Nice cryptic column names, by the way :)
Your research group obviously haven't researched very carefully, as
"+term" is exactly equal to " AND term", "-term" to " NOT term" and
simply "term" to " OR term". So there's no point in complicating the syntax.
Not only that, but MySQL's boolean mode fulltext search offers many more
great possibilities like truncation ("app*" will match "apple",
"application"...) and in-query relevance altering. Take a look at the
BOOLEAN MODE section of the MySQL manual [2]; maybe print it and give it
to your research group :)

Hi all,
I am new to PHP.
I know some thing about SESSIONS in PHP, I am in need of your suggestions.
how to use sessions ?
what is an efficient way to handle session_id ? like that.
How efficiently we can use session concept in our web site development ?
how it is helpful.
thanks in advance.

$_SERVER['SCRIPT_NAME'] and $_SERVER['ORIG_SCRIPT_NAME'] will give you the
current filename without the path.
I'm currently using PHP5.1RC so it might differ in your version but check
out phpinfo.php
These things are all displayed in phpinfo.php.

Also, just add a single line to your own test script and make it look
like this:
header('Location: http://www.php.net/');
$fp = fopen('/tmp/log.txt', 'w');
for ($i = 0; $i < 30; $i++)
{
$str = "Count $i\n";
echo str_repeat($str, 1000);
fputs($fp, $str);
sleep(1);
flush();

Then time how long it takes for the redirect to happen. Is it still
taking 30 seconds?
Yes, it still takes 30 seconds, but each chunk is now 8000 or 9000
bytes. This is with Firefox on Linux (my previous ad hoc tests were on
Mac, because I was traveling). I'd be curious to know what behavior
other people observe with any of these test scripts.
1. Rasmus's original test script:
header('Location: http://www.php.net/');
$fp = fopen('/tmp/log.txt', 'w');
for ($i = 0; $i < 1000000; $i++)
{
$str = "Count $i\n";
echo $str;
fputs($fp, $str);
}
When trying this one, my log.txt shows entries from 0 to 999999, so it
loops the full 1000000 times. I've checked ignore_user_abort(), and it's
false. You can set it in the script to be sure. If the browser aborts
and requests the new URL before the script finishes executing, the log
should reflect this.
2. Chris's original test script:
header('Location: http://www.php.net/');
$fp = fopen('/tmp/log.txt', 'w');
for ($i = 0; $i < 30; $i++)
{
$str = "Count $i\n";
echo $str;
fputs($fp, $str);
sleep(1);
flush();
}
This script takes longer to execute but generates less output. I was
thinking that perhaps browsers are only patient up to a point, but this
is not the case with the browsers I've tried. I get redirected after
about 30 seconds.
3. Chris's modified test script:
header('Location: http://www.php.net/');
$fp = fopen('/tmp/log.txt', 'w');
for ($i = 0; $i < 30; $i++)
{
$str = "Count $i\n";
echo str_repeat($str, 1000);
fputs($fp, $str);
sleep(1);
flush();
}
Rasmus modified the echo in my test script to output 1000 times as much
content. I thought this might work based on section 10.3.3 of RFC 2616
(I referenced this to try to determine why we are observing different
behavior):
"Unless the request method was HEAD, the entity of the response SHOULD
contain a short hypertext note with a hyperlink to the new URI(s)."
A few hundred thousand bytes doesn't seem like a "short hypertext note"
to me, but apparently size doesn't matter. :-)
If anyone can get a browser to redirect (request the new URL) before
receiving the entire 302 response, I'd love to know your test script,
platform, and browser. I have not been able to reproduce this.
Chris
