That won't work. Then I will get what the VALUE of $bar is set to. I want
the actual text "bar". Basically everything after the "$" -- ie. The NAME of
the VARIABLE, not it's contents.
The closest I've come so far is to do this.
Function myname($foo)
{
echo "variable named $foo has the contents $$foo";
}
Myname('bar');
Which is pretty lame.

set the domain of the cookie to 'server.org.uk', it's the fifth

Actually, you should set it to '.server.org.uk' which will make the
cookie valid for all *.server.org.uk hosts.

Hi!
I've begun to be more and more displeased with Apache lately, so I've
been thinking of writing my own HTTP server instead. I still want PHP
support, but writing a new SAPI for PHP seems like overkill.
What's so bad about Apache?
Therefore, is it possible to use PHP from the command line, but still
enable some HTTP-server-only stuff, like GET and POST variables,
cookies, session management, file uploads, and so on? I haven't been
able to find any docs on doing that, but I'm thinking that it should be
possible.
No, not really. $_GET and $_POST are populated by PHP from information
from the HTTP request (which, obviously, isn't available in CLI mode).
In CLI, there is no concept of cookies, sessions (as there are in web
world), file uploads, etc. What you get is what you would recieve with
any CLI app, command line parameters, and access to the system calls
that you can execute using exec() and friends.
I'm not really sure why you want to write your own HTTP server, as this
has been done many times over the years. What exactly are your issues
with Apache?
So, can someone either point me to some docs in this, or, lacking such,
give me a short intro to it?
For a decent CLI script, you will need to access the command line
arguments, for which there is a great PHP class over at PEAR. There you
will also find classes for color output on the console and other classes
that you will find useful.
FWIW,
Burhan

Hi all.
I have the week number (for example, this is the 29th week of the
year and it begins on 7/17/05). Does anyone know how to obtain the
first (and maybe the last) date of the week if you only know the week
number of the year? Would it be better for me to obtain this in PHP
or MySQL? or both?
I have researched the archives on a few lists and I know that others
have asked this same questions, but I have not found a good solution.
I have also looked on MySQL's "date and time functions" page, but had
little luck.
Any thoughts would be appreciated.
~Philip
Hi Philip
give this a go... i played around with the date functions of mysql
select date_sub(curdate() , interval (date_format(curdate() , '%w')-1)
day) as firstday , date_add(curdate() , interval (7 -
date_format(curdate() , '%w')) day) as lastday
it will give you the date of the monday and the sunday of the current week
hope this solves your problem.

Hi,
Its giving the line number. But actually i want to know the correct syntax for
concatenation. I think all there is some mistake in all the three concatination
statements.
so could some one check and give some idea.
thanks

No - there is no problem with any of the statements per se, but there
may be when executed with $adduser, $addpass etc. Why not take the
advice of Mark Rees and echo the $sqlstmt etc and show us the output?

For instance, take a look at:
http://www.php.net/manual/en/ref.mysql.php - this is the first page in
the reference manual about mysql. 'bout a third down the page
is...'Example 1. MySQL extension overview example' copy, paste, amend
as required and run. Doesn't work? PHP manual -> google ->
book....and...
...if then you don't understand, come back and ask - least it shows an
ounce of initiative which is what most on this list would like to see

It's not that you can't ask questions, it's that it's bad form to ask
numerous questions to which the answers are well documented. The people
on this list aren't here to hold someone's hand or write the code for
that person; we're here to help solve problems (or ask for help with
problems of our own). The questions you have been asking are really
basic, and if your book doesn't cover the answers, you need to look into
getting a new book. The online PHP manual is an excellent place to find
answers to the questions you've been asking, as is the mailing list
archives. This list shouldn't be your first stop when you encounter a
road block. Check the manual, the archives, and Google first. 9 times
out of 10, you'll find your answer there quicker.

what is it wrong to ask questions on a php general mailing list where I
know there are a bunch of people that can help? I do have a php book But
it's just that what you ask and how (coupled with the frequency)
determines the response you get, if any.
your general attitude, the number of posts you answer, etc, etc all
play a part. e.g. as is regularly mentioned you don't argue with Rasmus,
why? because he wrote the original php, still actively develops it, runs
yahoo, and _still_ has time answer posts on this list... basically
he know more than you and has enough 'credits' in phpland to buy the
bank (so to speak) -
...you blew most of your startup 'credits' already, so now you are 'forced'
do a lot of increaseKnowledge() where:
function increaseKnowledge()
{
while (kowledgeSucks()) {
readTheManual();
SearchTheWeb();
writeSomeCode();
}
}
then come back to the list when you are _really_ stuck and you can
explain the problem and what you have tried so far in _detail_...
if you do that then you'll almost garantee yourself and answer
there are no hard and fast rules regarding this but the consensus
is 'try harder please George' ... basically NRBS** doesn't entice people
to spend time working on _your_ problem.
it dosent show. Why can other people ask questions but I cant?
which book? show what? be specific, do research - google is your friend
(that's beginning to sound like something bigbrother would say).
regarding "Why can other people ask questions but I cant?" ... er?
that is a question, you asked it, ergo the question moot is moot...
what you should be asking is why other people get better answers ...
hopefully you get that now, anyway good to see you reading other people
threads.
rgds,

Is there a list which deals with basic certification questions and
anxieties? I got the 'official' Zend study guide and now believe I know
nothing. And the practice book has quests whose subjects are not
mentioned in the relevant chapters. If someone else has completed the
exam, which text did you use to prepare? I know O'reilly has Programming
PHP, but I fear trying to parse out what I need to know might be a
little difficult form that book...any ideas?

Thank you Rouvas,
I never used the tools you mentioned. But I will definitely give them a try.
I wrote a perl script using LWP as an http user agent. and the timing
function you suggested. It works well.
I am new to this forum, and new to PHP. It seems Rasmus is famous, and I
should have shown my respect.
Thanks again all of you for your kindly help.
Hi Liang,
trying to get conclusive results with browsers is futile. Use a
command-line
tool (like curl) to invoke the web pages and get the results. Or you can
use
PHP's own function to query the web server and do your own timing with
microtime() function or another suitable for your purposes.
In order for flush() results to reach you (in a browser) they have to pass
from multiple caches like PHP's, Apache's, the occasional proxies and
finally
the browser's own cache. So you cannot get dependaple results measuring
times
or responses from your browser. Try the methods above.
And a final tip... When Rasmus speaks, you don't question him:-) Period.
Have a nice day,

Hi André,
It sounds interesting. But since I am pretty new to PHP, I have some
questions, naive maybe, about what you wrote.
"#!/bin/sh\n/path/to/script/Send.php 12 &\n"
What does the Send.php look like? I do not have idea how a shell interprets
an php script and what the parameter 12 means here. If you do not mind,
could you please also let me look at your Send.php?
Thank you very much.
I did something like that for a newsletter sending script. Basiclly, I
had two scripts:
a) AddEdit.php that would list the newsletter's items and allow it to send
b) Send.php that was a script I ran on the background
When pressed "Send" on AddEdit, it would do something like
$tempName = tempnam( '/tmp', 'newsletter' );
$fp = fopen( $tempName, 'w+' );
fputs( $fp, "#!/bin/sh\n/path/to/script/Send.php 12 &\n" );
fclose( $fp );
chmod( $tempName, 0755 );
system( $tempName . ' &' );
That way, it would launch the second script into the background,
checking if the script altered the newsletter's state for "Sent"
everytime a user saw the newsletter's details.
Hope it helped.

Hi all,
I am trying to create a table on the remote server but it never seems to
work
CREATE TABLE `sheet1` (
`id` int(10) NOT NULL auto_increment,
`title` varchar(255) NOT NULL default '',
`fname` varchar(255) NOT NULL default '',
`sname` varchar(255) default NULL,
`job_title` varchar(255) default NULL,
`organisation` varchar(255) default NULL,
`email` varchar(255) default NULL,
`street` varchar(255) default NULL,
`city` varchar(255) default NULL,
`postcode` varchar(255) default NULL,

`mobile` varchar(255) default NULL,
`fax` varchar(255) default NULL,
`web` varchar(255) default NULL,
`add_info` varchar(255) default NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=303 ;
There seems to be a problem with the last line (this is exported from my
local server). I am just learning about mySql as I go so have no real clue
about CHARSET and ENGINE (which I believe may be the problem)
This is the error
1064 - You have an error in your SQL syntax. Check the manual that

There is nothing PHP here, but you knew that when you pressed send.
Really there are a lot of MySQL gurus on this list. There are a lot more
on mysql@lists.mysql.com
You're problem is likely related to the version of MySQL that you are
running, perhaps it doesn't support CHARSET definitions.

Just upgraded to 4.4.0 ... several "legacy applications" that we have
installed now break with the above error message ... specifically, older
installs of Horde, but I've seen reports of other apps ...
Without reverting back to 4.3.11, is there a way I can temporarily fix
this while working on the application issues themselves? :(
