Re: [PHP] Removing special characters
Computer Programmer wrote:
Is there a PHP built-in function to retrieve only the alphanumeric

I know that I can check for alphanumeric characters using the function
ctype_alphanum () but it won't retrieve the alphanum characters.
I also know that I can use str_replace to replace an array of special
characters such as the example below:
$str = I*m using html tags with special/chars like | how to get rid
of it???;
$removeChars = array ('*','?','|','','','/','\\');
$str = str_replace ($removeChars, , $str);
However, could there be a specific function for just retrieving
alphanumeric characters? or a specific function for just stripping
special characters? Or maybe a better way to do those things from the
example given above?

Yes, I tried sending the correct headers with the header function. For

Depends very much on the document type of your page. Valid XHTML

So the following link:

...should be changed to:
a href='http://www.somewhere.com/index.php?id=1amp;id=2'Something/a
Thank you Murray. The page is in xhtml 1.0/transitional. That was
precisely what I was worried about. The amp; will be converted as part
of the URL right? I mean, the printed URL resulting from clicking on
that link won't say amp; it'll just say is this correct? Combined
with Rory's post this is really, really useful stuff and I thank you !

Hehe, my soul is hard to please...=P
Actually, __get() does work from inside the class. In the sample code I
posted, func() does indeed return 'x' when called from main. It does not
work when called from within a call to __get(). In other words,
$this-attribute does not work if __get() appears anywhere in the call
stack.
Its just a small annoyance.
I think it would be more annoying if __get() would be recursively called

You should see a message from your browser that data is being reposted.
I looked for such a message and the only thing I can find is as follows:
1) _SERVER['HTTP_ACCEPT'] and _ENV['HTTP_ACCEPT'] and change to */*, but I
don't know if that is the case for all browsers, do you know?
2) _SERVER['REDIRECT_UNIQUE_ID'] and _ENV['REDIRECT_UNIQUE_ID'],
_SERVER['REMOTE_PORT'] and _ENV['REMOTE_PORT'], _SERVER['UNIQUE_ID'] and
_ENV['UNIQUE_ID'] change, but I don't think the values are predictable,
especially between browsers.
Do you know of a specific message to look for and is that message the same
for all browsers?
that's a message the user (using the browser) gets from the browser.
Unless you use GET method, but you should really use POST method for
forms that change state on the server.

my own, for data identified by session ID -- it doesn't really matter if

I know I could read the session files themselves, but I'd very much
rather use a proper way to retrieve the active sessions, which would
work with alternate methods of storing session data, if there is any
such proper way to do this.
I read the PHP documentation regarding sessions, and I checked out
Google, with no luck. If you guys don't have a solution, it means that
there is none -- in other words, you're my last hope, help! :-)
Depends on where and how you store your session data. Default file
storage simply reads all files in session.save_path (opendir() and
readdir()), check if they match the pattern /sess_[0-9a-f]{32}/ and the
modification time.

The echo statements in the Set4HTMLOut() function echos all the correct

htmlspecialchars() function appropriately. Notice that the caller passes
each variable as a reference. Yet, the echo statement after the call
displays the data without any changes, like the first echo statement in
the Set$HTMLOut() function does.
Is it not possible to pass variables by reference to a variable-length

I have already built a work around. I do not need any work arounds. I just
think one should be able to pass variables by reference to a function that

Re: [PHP] Any alternative to POST method FTP uploads from client computer?
Murray @ PlanetThoughtful wrote: Hi All, I need to implement the ability to ftp upload files from client machines via a form in a web application I'm developing. From reading the PHP help, all I can find to perform this is the POST method for handling file uploads (http://au2.php.net/manual/en/features.file-upload.php). From my perspective, while this seems to work, there are a couple of drawbacks, most important of which is that it seems you can only do comparisons of the uploaded file, against the potential that the file has already been uploaded, once the file has already been uploaded and is sitting in the server temp directory. This is a drawback to our application because the files can typically vary on a daily basis in size from 20mb thru to 400mb, and 400mb seems like a lot of bandwidth to consume to discover that the file already exists on our server. I had hoped there was a way in which I could retrieve stats of the file being uploaded prior to beginning the upload, to compare against files in the target directory, so that the application can advise the user that the file already exists and to give them the option to cancel the upload. PHP script starts once the upload is finished, but this is not true for some other languages, for example perl. Another minor drawback is that it seems the Post upload method changes the file datetime to the datetime of the upload. Browsers don't send file's modificaton time, so it's not available. So, can anyone confirm that there is no other way to upload files from a client machine using a form? (and assuming they don't have an ftp server at their end).

I know in JavaScript, that you declare vars like so:

So I'm assuming that in PHP you do it like this:
var = $variableName;
the above is wrong.
you can declare variable inside class definition using (php4):
var $varname [ = {default value} ];
but it's not necessery. It's good for documentation.
php5 gives you more control with public, protected and private keywords.
But there doesn't seem to be a single shred of documentation on PHP.net (or
in ANY book) that covers this. All they say is that it's good practice, but
not necessary. Then they always skip telling you how.
outside of class definitions you declare a variable by assigning it a
value, for example:
$myvar = null;
That's it.

Hi,
I have a table with 15 columns or so that has been inherited from an older
db and am trying to insert an auto increment column (in mysql) without
having to number it manually. This is fine when I add new colums via a form
but the old entries have a null value
Alternatively It has been converted from Excel soif anyone knows how to do
it that way that would help.I never use Excel so have no clue about it.

$id = 1;

Hello All,
Cosider this :

how do i skip the second argument while calling the function, is there
a process like this:
echo add(1,,1); # where i expect 2 to be printed,
php does not support this. you can workaround this using:
function add($a = null,$b = null, $c = null){
if(is_null($a)) $a = 1;
if(is_null($b)) $b = 2;
if(is_null($c)) $c = 3;

Re: [PHP] appending to a file using ftp functions
Giulio wrote: Hi, I'm developing an application that uploads file to a server using http. the app calls a php on the server sending all the data just like a web form post. It works just fine uploading little files, now i'm concerning about having the apllication split large files in little chunks ( about 256 KB os so ) and sending them with multiple post. Wanna do that to avoid possible problems with php temporary files max size. No problem on the client side ( is sends the form with some info and the firts chunk, waits for server response and then repost a form with succesive chunk of file, and so on ), and also on the php side should be quite easy to store a file with the first post, and keep on adding to it the subsequent chunks of file posted, at least using the filesystem functions. My problem is that I'm using, to make the system as general as possible, and make it work even on servers where php doesn't have write privileges, ftp functions instead of filesystem functions, and using ftp it seems that it's not possible to append to a file. I also thinked to use the fopen function with an ftp address, but reading the docs it says that fseek function ( to position the pointer at eof to go on appending ) may not work if the file is opened using ftp or http. Suggestion about this issue? ftp_put() has startpos parameter. I think you need to turn FTP_AUTOSEEK off, because you have only partial file. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] 32 bit PNG (256 color alpha channel), TGA images, etc
Andrew D. Keyser wrote: I find it not quite right that imagecolorallocatealpha is limited to 128 levels right now (0-127) ... the png format can support 256 with true 32bit images. I am concerned about this because I am using php to make an application that loads a nonstandard image format (MM2/MC TEX) and converts it to png - but the format supports 256 alpha levels, imagecolorallocatealpha does not, and therefore I am losing small amounts of detail in the alpha channel by reducing it to conform to the max 128 levels idea. Can I get an explanation as to why it's limited at 128 levels instead of the preferred 256, and maybe an estimate or guess to whether or not this limitation will ever be lifted? On to the next part of this post. Is there any way to create an equivalent to imagecreatefrompng for tga (maybe imagecreatefromtga), /including/ alpha channel? I've found examples on php.net, but none of them take an image with more than 256 colors, much less one with an alpha channel. I'm not keen on the binary structure of the tga format, but i might be required to learn it this time.. Andrew It's likely limitation of gd or png library.

Re: [PHP] php output fills apache buffer for clients with slow internet connections
Martin Mandl wrote:
Dear Ladies and Gentlemen,
the last couple of days I browsed the internet for the answer of a
questions which seems to be a common problem ... but found now real
solution:
I would like to serve large files (100MB) to my clients using php:
while (moreDataAvailable()) {
printChunk(getChunk());
flush();
waitToReduceBandwidth();
}
Normally that works fine. However when the client has a slower internet
connection than I set using waitToReduceBandwidth() the output of the
php script builds up in the buffer of Apache. ... and the Apache process
reaches a couple of hundred MBytes ...
A solution would be to reduce the bandwidth so that is even lower than
the slowest connection ... but then clients with faster connections
would complain ...
Therefore (finally) here come the questions:
Is there a way to control the output speed of the php script according
to the actual download speed between the browser and the server?
Or is there a way to monitor the memory usage of the apache process (to
slow down the data output when it increases)?
Or is writing my own socket to act as web server a solution (is it
possible to monitor the connection speed this way)?
Or what should I do else?
Any hints are welcome, cheers
Martin
