Actually you can. Try using session variables.

I can't think of any reason why not. Obviously this won't be a web
application :) Though a good design could be re-used to form an online
ordering application also.

God yes, the guy seems to think that OOP is the do all end all style of coding...
personally I like to hybrid OOP and prcoedural concepts which you can't do in
Java. Also lots of other issues that he doesn't take into consideration such
as the task at hand and the appropriateness of one solution over another for
that task.

Re: [PHP] long running PHP application

[Robert Cummings]

I run a fantasy MUD and I have a PHP based daemon which checks for in game
player mail and if found and the player has registered an email address, then
it sends the MUD mail out to the player's email address. The program wakes up
once a minute to check the database and then goes back to sleep. It's been
running for months without a problem.

Cheers,
Rob.

I don't know if it helps... but you should take a look at the ini_set()

[PHP] A question of time...

[Robert Cummings]

Hi all,

I recently had a freelancing experience that has left me somewhat sour and
questioning myself. Unfortunately I don't feel I can fairly evaluate myself
and so I owuld like to put the question to my peers who populate the PHP
forum as to whether I have performed competently.

Last week I took upon myself the task of fixing a clients shopping cart
system by way of adding session support and proper user registration
validation. To give you some idea of the parameters of the job...

- VNC development connection
- live server with no error output
- no session support whatsoever
- cart had no input validation, except basic javascript
- user registration permitted clobbering of other users
  and had no validation either
- PHP code was ad-hoc sprinkled through the pages
- comments were almost non-existent

The first day I decided it would be best to mirror the server so that
development time would be minimized (VNC is terrible for devlopment). This was
done without charge to the client despite it's time saving effect.

The second day I spent 13 hours familiarizing myself with their code and
pages, and on this day I also implemented a session management library for
easily accessing and setting session data (this included hooks for permanent
cookie data storage). I also fixed the user registration process and add
security validation to ensure user information could not accidentally (or
deliberately via form hacking) be accessed by someone other than the
registrant. Previously re-registration of an existing email address regardless
of password would clobber existing customer. At this time I also fixed the
cart and ensured prepopulation of forms for updating registration information.

The third day I first wasted an hour making my changes work on their
server because they decided to rename all the files I had changed thus
breaking all of the include() paths. After that I spent another 3 hours adding
support for returning to previous page before entering any of the cart
checkout or customer registration pages. At this time a response page was also
added to thank the customer for their purchase. Of course all of this was
tested to be functional and where necessary broken pre-existing code was
replaced or fixed to provide the correct functionality.

On the fourth day I spent 3 hours adding support for input validation
feedback to the registration validation so that customer's would know exactly
why they could not continue. I also added support for a password reminder to
inform the user of their password when forgotten. This included adding the
page, adding the form, validating that the user id existed and outputting
appropriate feedback if the user did not exist - and of course testing.

All in all I spent 20 hours total for the client at a rate of $40 USD/hr
which I believe is on the low end of freelance. I myself have 3 years
experience devloping PHP web applications. So the question I ask is whther
this time frame is reasonable, or am I just a slow crappy programmer that is
ripping these people off? They seem to think I should have had this done in
just a few hours, but my experience thus far indicates to me that they got
just service. Additionally it seems before I took the job, they had went
through several other PHP developers would said they couldn't do it (and I
don't really blame them considering the VNC connection and lack of comments or
error feedback).

If it turns out that I am incompetent, then I will happily send them a
bill for zero hours, otherwise I would like to take comfort that I am not
ripping them off.

Sincerely,
Robert Cummings

Thanks, I did estimate 20 to 30 hours for them after I had set up the mirror
server and before the actual work began. At the same time I asked if they wanted
me to stop to which they replied that I should continue.

Cheers,
Rob.

Re: [PHP] Do query strings get spidered by Google?

I don't think Google follows URLS to every variation based on a query string.
I know to have some of my pages indexed I had to rewrite the URL so the query

The cast isn't necessary, PHP happily transforms it for him when he
applies the ++ operator.

I am absolutely sure of thus since I cut and pasted the original problem
code to a shell script to test. This was before I noticed the answer
mentioning the closing if block had already been posted.

Undoubtedly the above will work as we both know, the output will be
"123"; however, if you look at the original code in question, there is
no "\n" tailing the output written to the counter file and thus the
increment works fine (unless of course when he created the file to begin
he had a newline - something I did not do in my test :)

Rob.

Re: [PHP] Too much of $GLOBALS[] a problem??

Rather than having the following scenario:

$GLOBALS['fee'] = 'fee';

The following would be much cleaner and portable while still allowing
the ease of use of $GLOBALS based configuration:

$GLOBALS['myProjectName']['foo'] = 'foo';
$GLOBALS['myProjectName']['fee'] = 'fee';

Using your above example, the above would keep all of the internal data
that keeps track of the resource ID (for the connection), the current
result set, and the current row, etc. within the object instance scope.
Thus everytime you invoke a method on the object it works with it's own
set of data. In all honesty you can do this with functions also, but
then you would have something like the following:

$dbId = db_connect();
$data = db_do_this( $dbId );
$moreData = db_do_that( $dbId, $data )

As you can see this quickly can become cumbersome becaus eof the lack of
encapsulation. However, the OOP paradigm goes even further. Lets imagine
you now want log all use of your functions (methods :). To do this in
OOP you just extend the class and override the methods while still
allowing invocation of the inheritted methods. Thus your usage of your
new object code would look something like follows:

$db = new custom_db_sql;
$db->connect();
$db->do_this();
$db->do_that();

Whereas the function code would resemble the following:

$dbId = custom_db_connect();
$data = custom_db_do_this( $dbId );
$moreData = custom_db_do_that( $dbId, $data )

As you can see updating the function based code required more work. It
wasn't as modular since it couldn't take advantage of inheritance. This
is a trivial example btw, it's not perfect since there are books and
books written on this topic and I'm obviously glossing over a lot of
details. Once you get into design patterns you'll also see other
advantages of using objects versus functions. I hope this helps a teeny
weeny bit.

Cheers,
Rob.

Object Oriented Design is not an industrial theory. It's a tried and
true practice with over a decade of computer science and practical use
behind it. Procedural programming is a subset of Object oriented
programming. Someday you'll need the higher level features OOD offers,
but until then it probably just won't make sense unless you actually go
and learn the principles from a good book or teacher. Trying to
formulate an opinion about OOD from the PHP mailing list is like trying
to form an opinion about nuclear physics from your buddy that watched
some show on nuclear power plants (maybe not that extreme, but hopefully
you get the point).

Re: [PHP] controlling winamp with COM

[Robert Cummings]

Depending on exactly how you intend to use this technology there are
several ways to go about it. One is to create a PHP C extension that you
compile into the PHP engine itself -- this I imagine can hook into the
API to control the open application. Then you can choose to use these
new extension functions in either a shell script to control the winamp
program from the current computer (or shell-script on a remote computer
that you SSH or telnet into), or you can create a PHP-based Web front
end to control the winamp application. The other alternative, is to just
have the PHP script call existing programs than can access the API on
the OS via the backtick or system(), etc... functions (this solution was
mentioned below :). It might even be possible that Winamp itself
provides hooks to a running instance of itself via command line
parameters (one can hope) which would simplify the task greatly.

Cheers,
Rob.

PHP handles it fine -- I've been using it in my code for years now
without a single hiccup. With thousands (millions?) of others using it,
the assertion that PHP cannot handle "it" seems unequivocally incorrect.
That said it is more likely than not, that you yourself are unable to
handle "it". Furthermore, your style and mannerisms remind me of a
troll.

ASP merely outputs HTML. His table is basic HTML dynamically rendered

That kind of thinking leads to things like Hitler :| If we never say
anything then it becomes the norm for people to continue their
behaviour. Currently the question being debated is what constitutes poor
behaviour/etiquette within this mailing list. While I agree that this
forum is primarily for answering questions -- I disagree that it is for
answering silly little questions that would be common knowledge if the
asker had bothered to read any tutorials or documentation -- most
especially when it appears that the poster didn't even bother to do any
kind of searching for themselves. I mean really, questions like "does X
do Y" is often as simple as writing 1 to 5 lines of test code which is
probably shorter than the email itself and doesn't pollute the mailing
list with 5 to 10 replies of "yes" or "no".

Re: [PHP] detecting referer

You can get referrer information from the following:

This isn't foolproof though since the user can usually set in their

Re: [PHP] Question on class syntax

[Robert Cummings]

The :: operator is used to access a static class method. In other words
you can use the class method without creating an instance of the class.

Alternatively you could have used the following less effcient syntax:

$cleaner = new htmlcleaner();
$value = $cleaner->cleanup( $value );

Rob.

Re: [PHP] htmlspecialchars() and HTML code

You're safe because when you apply htmlentities() these will be doubly

"&".

This is usually solved with a virtual host which has virtually no impact

Forgive me if I'm ignorant, but it appears that you've answered your own
question in the above example -- the case being that it is indeed
possible.

RE: [PHP] Freelance code optimizations

[Robert Cummings]

In that case it makes perfect sense since a concatenation is not
actually performed. The loops stuff though might be more tricky to
determine reasoning. I imagine it has to do with the execution tree and
references being created at various stages. Probably the for loop has an
extra step or two which over a large loop can produce noticeable
results.

Cheers,
Rob.

Re: [PHP] PHP - Interpreted or Compiled Language

[Robert Cummings]

While is is true that the opcodes cannot be run as machine code, the
opcode (bytecode) can be run on any machine which has the PHP engine (or
an opcode reader). Does Java not call itself a compiled language? If so
then the simple addition of PHP Accelerator, or Zend Accelerator should
be sufficient to call it a compiled language. Anyways I can't really say
for sure, traditional scripting languages didn't create such blurry
lines between compiled and interpreted :)

Re: [PHP] PHP Session Problem!.....urgent!

[Robert Cummings]

The root of your problem is that sessions generally do not traverse
multiple domains. A possible solution is to embed an image in each of
the servers which references a PHP script in the other server, and while
doing so passes the sessionID along.

On server abc.foo.org you might have the following:

http://xyz.foo.org/sessionMap.php?sessionId=123456789"; />

While on server xyz.goo.org you would have the following:

http://abc.foo.org/sessionMap.php?sessionId=123456789"; />

What this does is create a session on the other server even though the
user has not "seemingly" visited it. By passing the original session ID
you indicate the session ID that should be used for the new session and
thus bypass any session ID generation. Then if the user visits that site
they will already be set up, and provided the session data is stored in
the same database for each site then all information will be
transferable.

The image which accesses the other server's sessionMap.php script would
only need to be output to the browser when a new session is created.

HTH,
Rob.

As I stated already, they'd know how to ask the question if they

RE: [PHP] Stop neurotic posting

[Robert Cummings]

Your example is ridiculous -- it looks like you want a search egnine to
properly phrase the question for you.

This works and is more concise and clear: php find a string in a string

Really, I don't think people should be using the mailing list in lieu of
purchasing a book on PHP or reading one of the many online tutorials.
After you've acquainted yourself with the language, the syntax, and some
coding style (I hate the "anyone see what's wrong with this [insert your
favourite piece of self coded 1000 character long mess here]), then by
all means ask questions which are troubling to you. I rarely answer
questions anymore because I find that many people want the coders on the
PHP mailing list to do their work for them because they're too lazy to
bother doing some research. Also to get back to the problem of wording
queries wrong in google or whatever -- maybe trying a fwe different
queries would help. Anyways this is all just my humble opinion.

Cheers,
Rob.

RE: [PHP] How to point at a spot and get relevant information?

[Robert Cummings]

Since PHP plots the data according to the information in the database
then you know about where the data is located in the image. If PHP works
on a single plot coordinate then you need to increase the acceptable
clickable region and use this to find your point (otherwise people will
need to click on the exact coordinate pixel.

For instance:

To go back to my earlier Ottawa example. You have a coordinate in
your database for Ottawa, let's imagine it is 1030, 720. To make an
acceptable clickable region we could decide that 5 pixels on either side
is acceptable for retrieving the information. By doing so we define a
bounding box for the location of the data. The rectangle would be:

   ottawa.x - 5, ottawa.y - 5, ottawa.x + 5, ottawa.y + 5

Now, since you want the information when the cursor is pointed at the
coordinate and not when the user clicks the coordinate you are
restricted to using a client side technology to determine what data to
display to the user (Javascript, Java, whatever else). This also means
you will need to send all of the information about locations in the
image to the user (possibly dynamically produced Javascript code). If
this is to be done then you are probably better off to calculate the
bounding box constraints at the client side, rather than on the server
and sending the extra data.

HTH,
Rob.

Re: [PHP] Hitler and Recent Threads

[Robert Cummings]

The so called Nazi clause is itself the invocation of Godwin's Law. Your
reading skills are flawed or you could have determined this from the
abounding literature available on the Web. Also there are many examples
of Godwin's Law being invoked and subsequently Quirk's exception being
raised. Thus said, having reviewed precedence, my usage of Quirk's
exception is correct and contrary to your misunderstanding.

Admittedly now I'm wasting my time (big deal), the group's time (sorry
all), but probably not your time. Future attempts to troll me into a
retarded discussion of the merits of Godwin's law or any other off-topic
fork from the original thread (regardless of how wrong you are -- which
will more than likely be the case) will be met with silence. 'Nuff said.

Re: [PHP] delete line

[Robert Cummings]

If your file isn't too large then you can use:

$lineArray = file( $pathToYourFile );
unset( $lineArray[$lineNum - 1] );

if( ($fl = fopen( $pathToYourFile, "w+" )) !== false )
{
foreach( $lineArray as $line )
{
fputs( $fl, $line );
}

fclose( $fl );
}

Note that the above has not been tested. If your file is quite large,
you will probably be better off reading in each line one at a time and
writing out the line to a temporary file when it isn't the line your are
trying to omit. Then replace the original file with the temporary file.

HTH,
Rob.

RE: [PHP] How to point at a spot and get relevant information?

[Robert Cummings]

The ability to determine relevant information strongly depends on what
you know about the information you are displaying to the user. I'm
assuming you know about the information you are presenting to the user
and so it should be possible to map the coordinate system that the user
interacts with, to a global coordinate system for which you have
information about given aspects of the map. If you don't already have a
relationship between the graphics you are working with and the relevant
information, then this is probably your starting point. For instance if
it were a map of a city that occupied a rectangle of space on the
graphics (this is simplified since it could be any polygon), you would
probably have two coordinates that indicate a bounding box for that city
on the global map.

0,0
.---.
|   |
|   |
|   |
| * Ottawa  |
| [1024,718 to 1035,726]|
|   |
|   |
`---'
 2500,1500

Thus a coordinate where the following holds:

(x >= 1024 && x <= 1035 && y >= 718 && y <= 726)

would correspond to the city of Ottawa. These coordinates could easily
be stored in a database for easy lookup by your PHP application.

Anyways I hope I'm understanding your problem correctly.

Cheers,
Rob.

I've never seen a "comma" concatenation operator in PHP and the
following when cut and paste to a test PHP script generates a parse
error under PHP 4.3.2. Could you elaborate on this operator? Is it part
of the PHP 5 engine? Or are you mistaken in assuming the following works
when perhaps you use this style as part of an echo statement normally.

Hitler began his conquest by taking a country here, a country there
while other countries sat around saying to each other oh he won't keep
doing it. Let's DO NOTHING! Obviously that plan was flawed -- and that
is what I was referring to -- not that by being quiet suddenly the world
will be plunged into war again (not that it isn't already).

Re: [PHP] Freelance code optimizations

[Robert Cummings]

Comparison to a variable is expectedly slower since the engine must
perform a lookup into the running script's variable list. Since a
constant doesn't require a lookup it's access time is O( 1 ) whereas the
lookup of a variable will lie someplace between O( 1 ) and O( lg n )
depending on the algorithm used.

I get the following results (very consistently +/- .1) which agrees with
your results and also shows an improvement over your own optimization.

for( $i = 0; $i < 1000; $i++ ){}

Notice the large difference when the incrementation occurs within the

Re: [PHP] Forms

[Robert Cummings]

If I understand your question correctly it sounds like you want to
populate a database on Server A with data residing in a database on
server B via a form hosted on server A *grin*. Obviously this is
tedious, and if there are a lot of entries then I would suggest writing
a script to populate and submit the form automatically. If you are lucky
everything will be done via HTML GET method (URL parameters); however,
it is more likely that it uses the POST method. You can do some reading
into posting data via HTML request headers, or you can look and see if
there is a class that does what you want in PEAR or PHP Classes.

HTH,
Rob.

Re: [PHP] Forms

[Robert Cummings]

As I mentioned already you would be best not using Javascript and
performing the submission via PHP. I wrote the following snippet in the
past to do something similar to what you are asking. Study it and see if
you can adapt it to your own needs. You should be able to loop on the
form submission but you may want to disable script time limit if you
expect that this will take a while.

function submitForm( $host, $path, $data )
{
$headerString =
'POST '.$path.' HTTP/1.0'   ."\r\n"
   .'User-Agent: Lynx ;)'   ."\r\n"
   .'Host: '.$host  ."\r\n"
   .'Accept: */*'   ."\r\n"
   .'Content-type: application/x-www-form-urlencoded'   ."\r\n"
   .'Content-length: ';

$postData = '';
foreach( $data as $key => $value )
{
$postData .= urlencode( $key ).'='.urlencode( $value ).'&';
}

$postData = ereg_replace( '.$', '', $postData );

$headerString .= ''.strlen( $postData )."\r\n\r\n";
$headerString .= $postData."\r\n";

$content = sendRequest( $host, $headerString );
$content = implode( "\n", $content );

echo 'CONTENT'."\n\n".$content."\n\n";
}

function sendRequest( $host, $header )
{
$fp = fsockopen
(
$host,
80,
$errno,
$errstr,
30
);

$data = '';

if( !$fp )
{
echo "Error: $errstr ($errno)\n";
}
else
{   
fputs( $fp, $header );

while( !feof( $fp ) )
    {
$data .= fgets( $fp, 128 );
}

fclose( $fp );
}

return explode( "\n", $data );
}

Cheers,
Rob.

Re: [PHP] How to point at a spot and get relevant information?

[Robert Cummings]

ou should be able to use an image map form input widget to get the
coordinates that the user selects from some image you display to them.
Then the determination of relevant information can occur server side via
PHP. I don't have experience with this, but it appears to be how
mapquest works:

[PHP] Discussion: do you consider null a value or strictly a type?

[Robert Cummings]

There has been a recent thread on the internals list as to the meaning
and usage of the "null" datatype. Zeev claims, perhaps rightly so, the
following:

Zeev wrote:
>
> null is not a value, was never meant to be a value, and won't be a
> value

Interestingly though, the PHP documentation at

http://www.php.net/manual/en/language.types.null.php

indicates the following:

The special NULL value represents that a variable has no value. NULL
is the only possible value of type NULL. 

Which is obviously contradictory since it claims to be a variable having
no value and yet also claims it is a special value. Also the following
snippet from: 

http://www.php.net/manual/en/language.operators.assignment.php

seems to also indicate that null is a value -- namely:

The basic assignment operator is "=". Your first inclination might
be to think of this as "equal to". Don't. It really means that the
the left operand gets set to the value of the expression on the
rights (that is, "gets set to"). 

The above reference might not be obvious, but since you can assign the
null constant, then it says the "left operand gets set to the value
of..." seemingly indicating that null is a value.

Now the point of the discussion is not to indicate who is right or who
is wrong -- that would appear to be a ridiculous argument. I am more
interested in finding out the practices and experience of PHP
developers. I'd like to know how many people treat null as a value, and
how many do not. For instance to you ever assign default values of null
to instance variables, or local variable, or array entries? I know in
practice that I have, and find it quite convenient to represent a
default value.

Cheers,
Rob.

Re: [PHP] Re: back button and forms

[Robert Cummings]

GET method has restrictions -- you are only guaranteed proper handling
of the first 1024 (or some such limit) after which the behaviour is
considered undefined. Thus using the GET method is generally only
feasible for small forms.

Rob.

Doubly threaded red-black trees are good for in order traversal and
arbitrary lookup. As with most structures that provide more speed, you
use more memory :)  O( lg n ) insertion, O( lg n ) deletion, O( lg n )
search. Threaded means the in order nodes are threaded into a linked
list. PHP I believe uses hashes of some sort, I'm not sure how they keep
track of the insertion order for doing a foreach loop -- I guess we
could look. On a more related topic: if he's happy with the unset()
function but wants the indexes renumbered, he could write a C function
which performs the renumbering. Should keep it relatively fast and
provide the option of renumbering -- or not.

Rob.

Re: [PHP] Re: google style paginating

[Robert Cummings]

Ummm I wouldn't do what these guys suggest (at least not all of it)...
perform two queries, one counting the total number of returns the other
to actually get the subset. Don't retrieve ALL the queries then only
display a subset. Otherwise what's the point of using the LIMIT clause
for conservation of resources? The "SELECT COUNT( * ) FROM foo" query is
usually optimized to be extremely fast so the first query is almost
negligible in contrast to the second.

Rob.

Re: [PHP] Clean Up the sand box time

[Robert Cummings]

Absolutely, the best way *tongue in cheek* is to format as follows:

$news = mysql_query($sql) or die( print "document.write(\"".mysql_error()."\");");

$found = 0;
while( $mydata = mysql_fetch_object( $news ) )
{
if( $getaddr == $mydata->IPAddress )
{
$found = 1;
}
}

if( $found > 0 )
{
echo "document.write(\"$getaddr already visited. \");";
}
else
{
echo "document.write(\"insert $getaddr into $table. \");";
}

Look how neat that is, who could possibly come up with a better style of
formatting than that!?

Cheers,
Rob.

Re: [PHP] Using PHP to get size of mySQL data?

[Robert Cummings]

Untested, but looks about right:

select sum( length( article_text ) ) as total

where user_id = 'user to match";

This is SQL though, so it's kinda OT.

Re: [PHP] Status Chaing Toggle / Code

[Robert Cummings]

Code and query look about right -- my guess is you're another one of the
multitude of people who haven't bothered to read the docs about register
globals and how they are now off by default. If the following solves
your problem, then yes indeed, such are you.

include("../../application2.php");
$CFG->dbname = "ipo_students";

//
// $student_id probably came in from $_GET or $_POST.
//
$student_id
= isset( $_GET['student_id'] )
? $_GET['student_id']
: (isset( $_POST['student_id'] )
? $_POST['student_id']
: null;

if( is_null( $student_id ) )
{
echo 'You have some other problem!'."\n";
}

db_connect($CFG->dbhost, $CFG->dbname, $CFG->dbuser, $CFG->dbpass);
$qid = db_query("SELECT printed FROM outgoing_student
 WHERE id=$student_id");

Legalize is very specific. If the contract didn't specifically state
that rights to the intellectual property would be part of the deal, then
he has merely sold a solution, not the rights to the intellectual
property itself. many companies are contracted for solutions, many
companies retain the rights to their intellectual property after
completion of the solution. Unless the contract is clear, he has done
nothing unethical or unprofessional.

Re: [PHP] Re: math functions?

[Robert Cummings]

Just to be precise, modulus does NOT return true and false. Given A%B it
returns the remainder after dividing B into A. This happens to be
equivalent to false when there is no remainder, and equivalent to true
when there is a remainder.

Cheers,
Rob.

Sequential if() statments will not be the same as the if-elseif() system
when more than two conditional checks are matched. The sequential will
process both blocks, whereas the if-elseif() will only process the first
match :)

Re: [PHP] Automatic Headers and Footers

[Robert Cummings]

Yes it can be done, using the auto-prepend feature call a script that
turns output buffering on. Then in the auto-appended script read the
buffer a manipulate ith with the automatic header and footer. Thus you
modify the content only and achieve what you want without modifying 
the actual HTML file.

The reasonn for my "difficult" answer was because the criteria for his

Thus the above solution is invalid :|

[PHP] buildconf doesn't seem to be working for 4.3.2

Puzzling as heck, the buildconf just took, perhaps was related to the

started mucking with that. incidentally it worked even though the
contents weren't changed *pffft* :)

Re: [PHP] piping email directly into PHP

[Robert Cummings]

Just a small addendum, I also suggest using -C if you are using a non CLI PHP
binary. This prevents PHP from changing directories to the location of the script.
Perhaps not important for your needs, but if like me, you do many shell based
scripts without the CLI version, it is very useful.

Cheers,
Rob.

Re: [PHP] which is quicker? pseudo XML, or database?

[Robert Cummings]

I you don't expect to do much with the data then I would recommend using an
SQL table since then you can easily search on all of the fields. Later if you
find you have more needs then conversion to XML will be trivial. Regardless
of which route you take if speed is an issue you can always cache either the
parsed XML or the SQL query results. It doesn't make much difference.

Rob.

Not to quibble (ok JUST to quibble :) It isn't correct XML because it
has no root tag *heheh*.

Re: [PHP] Re: speed on XML files

Try compression, XML generally cmopresses very well since it is usually text.

I realize this problem has already been fixed, but if messy developers took
the time to format their code into something readable (my suggestion below)
then finding such trivial errors would be a walk in the park.

$fine = mysql_query
(
"INSERT INTO tblPOItems "

   ."poItemNumber, "

I'm not sure how you would go about doing this, a more natural
solution IMHO would be to incorporate your C code into a PHP
extension which would then give you access to the C library you
have written directly in PHP.

Re: [PHP] Expensive WEB HOST NEEDED!!!!!

[Robert Cummings]

Do we really need all this pessimism?? I have the exact host he needs. It
supports PHP, MySQL, and sending emails. It has absolutely no pop-up ads
and no watermarks. There is no advertising whatsoever. And the best part...
it is ABSOLUTELY FREE!!


ABSOLUTE FREE[tm] hosting is available only to those members of an elite
group of suckers that make monthly curtesy donations of $1000. Account will
be activate upon receipt of first donation.

Re: [PHP] Re: php caches mysql connections to same host

[Robert Cummings]

See the new_link parameter option for mysql_connect. It should solve
your problem. On the other hand, what you are doing is fine, I did it
for my pool since I can't use the new_link option because I'm retaining
compatibility back to PHP 4.1.2

This is hardly perfect since it shows all errors, but it works for me:

I'm asuming you are executing something like the following:

php myPhpScript.php

The following will probably give you the desired results...

php -qC myPhpScript.php

This prevents PHP from switching out of the current directory.

HTH,
Rob.

You are trying to execute a bash script from PHP though. When you invoke
the php engine it usually changes directory (to the root defined in the
php.ini I think). To stop this so that it will remain in the current
directory so that when you run bash it will see the bash script in the
current directory, you need to use the -C command line option. I believe
your environment is inherited by php and subsequently bash and so if
you don't use the -C option bash will be looking in the wrong directory.

Cheers,
Rob.

Have a php script authenticate the user, then if authenticated, use the
reafile() function to output it to the user directly. Since PHP can see
more than just the web space the files just need to reside outside of
the websapce.

Cheers,
Rob.

If you set the mime type properly the browser will
automatically make it a download versus displaying it.

Cheers,
Rob.

There are a number of things you may find useful to read about in PHP:

chmod
chown
umask

Also you might want to look into the sticky bit for directories. Someone
feel like adding more about sticky bits... I'm pretty vague on them, just
know when they're set (and I don't remember how to) that files written
to the directory inherit group ownership.

Cheers,
Rob.

Re: [PHP] Any netscape users out there?

[Robert Cummings]

Netscape 4.xx series is notorious for caching issues. When you post data and then
try to view the source code netscape thinks it has expired and thus gone. Another
issue is when you resize the view source window, netscape reloads the page *ack*.
On my site at http://www.wocmud.org I think my no cache headers even cause netscape
to choke since I can't get page source on any of my pages in the 4.xx series. My
solution is to use Mozilla/Netscape 7 to view the source when I need to and just
use the 4.xx brokwser when I want to make sure it looks ok visually.

HTH,
Rob.

Shouldn't be any bleeding from shared libraries. but then I'm on Linux
and your probably under windows, and so I don't know for sure anymore :)
