Dear List -
Thanks for all your help in the past. Â Here is another one...
I am getting a Permission Denied message when I try to run a PHP
script. Â I
just changed the mode on the directory and the files to 777. Â This
problem
arose when I changed the permissions. Â I thought I was solving a
problem,
because I could not open a file for writing. Â I was not receiving error
messages, but no file was created.
Help and advice, please.

The problem persists. I cannot write to a file from PHP.
Any more suggestions?
Thanks.

Hi Ethan,
Are you using suPHP or suExec? I believe the server chokes on 777
permissions in those cases.
Have you checked the permissions in the command line (sorry for the basic
question, but just making sure I know what you've already done?)
Also, can we see some of the code you're using to handle the file
processing?
Thanks,
Adam

Adam -
Thanks.
1] Pardon my ignorance but I do not understand this - Are you using suPHP
or suExec?
suPHP and suExec are two modules that allow PHP to run with the permissions
of the user, making it easy to write files to disk. However, suPHP (and I
believe suExec, but I can't remember for sure) does not like 777
permissions.
2] I changed the permissions to 755 and the Permission Denied message
went away.
Check!
3] Have you checked the permissions in the command line? Yes
Check!
4] Here are some code snippets:
$fptr1 = fopen(chessboard, r+); //this works
$fptr2 = fopen('chessboard', 'w'); //this deletes the file, as it should
for($i = 0; $i 8; $i++)
{
for ($j = 0; $j 8; $j++)
fprinf($fptr2, %s , $results[$i][$j]);
fprinf($fptr2, \n);
} //this never writes, so I am left with an empty file
Can you try a simplified form that checks for success along the way? How
about something like the code below to see how far it gets (I haven't
tested, but it should be close):
?php
// let's make sure you see the E_WARNING errors if present for file
functions
error_reporting(-1);
// set var for later
$cost = 120.89;
if (!($fp = fopen(test.txt, 'w'))) {
echo Can't open or create file!;
} else if (!($len = fprintf($fp, In the year 3000, a Coke will cost %01.2f,
with tax., $cost))) {
echo Can't write to file!;
} else if (!(fclose($fp))) {
echo Can't properly close file!;
}
?
What do you see if you run this?

Hello All,
Is there a smarter way to do includes by setting up a path or something
where I don't have to include /home/domain.com/includes/include_file.php

/includes/include_file.php
I wrote about this a long time ago ... perhaps it might help:

Talks about putting your functions into classes and using the autoloader to
avoid putting include statements in your code.
Might not help if you are loading content which is not just PHP
functions/code, but if you haven't evolved this far yet, the read might

Hi all,
I am using Codeigniter framework, tho' I believe my question is more PHP
related in general.
Problem I am having is following.
Codeigniter (CI) uses general class CI_Controller for all functions.
I have extended this controller with: abstract class CORE_Controller
extends CI_Controller {...}.
Then, I also have a RESTFul library which is:
class Cpin2_rest {}
And, last one is Ion Auth library which states:
class Ion_auth {}
In the Ion auth, there (should be) is initialization of CI_Controller with:
$this-ci = get_instance();
However, $this-ci inherits Cpin2_rest instead of CI_Controller (or
CORE_Controller).
I really have no idea where have I made a mistake and can't get around
this one :(
Any help is appreciated!
Thanks!
Aleks

Hi,
Yes indeed you are correct.
Found out that framework was loading libraries from array in specific
order, whereby one overrules the next one.
Anyway, problem solved by rearranging the order of the array :)

Can I make a jpg image from a jpg one, and a png image from a png one? And what about gif's? Yes, or even a JPEG from a GIF, or a PNG from a JPEG, etc. But: imagecopyresampled works on image *resources*, which you create either as blank canvases or by reading from files. In your case, you want to create a resource from a file (JPEG, PNG, GIF etc.) and another as a blank canvas into which you will copy the original image, resampled (or resized). See the examples here: http://au2.php.net/manual/en/function.imagecopyresampled.php After the comment // Resample it: * creates a new blank image resource to copy into, i.e. $dst_image * creates an image by reading a file, i.e. $src_image * copies with resampling, i.e. from $src_image to $dst_image 2. I don't need to output the image as the script output, I need to upload it as a file (replacing the uploaded larger file). Could I make it with fwrite and then copy it to the server? All of the examples give header(image/jpeg)... You can write the new image to a file using one of these: http://au2.php.net/manual/en/function.imagepng.php http://au2.php.net/manual/en/function.imagejpeg.php http://au2.php.net/manual/en/function.imagegif.php NB: see the following comments by tim (at) leethost (dot) com, regarding performance of imagecopyresampled vs imagecopyresized: http://au2.php.net/manual/en/function.imagecopyresampled.php#77679 http://au2.php.net/manual/en/function.imagecopyresampled.php#72606 Also check out ImageMagick, if your host provides it (or you can install it): http://au2.php.net/manual/en/book.imagick.php -- Ross McKay, Toronto, NSW Australia Let the laddie play wi the knife - he'll learn - The Wee Book of Calvin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

What do you see if you run this? Can't open or create file! Ethan OK, If you're running PHP as an Apache module, by default it won't have permissions to write to the directory (this is by design to avoid security issues.) You can do something like the following: 1. Create a directory for writing files outside of your public directory (let's call it uploads.) 2. Change the group associated with the directory to Apache: sudo chgrp -R www-data /home/username/path/to/uploads 3. Change the permissions on the directory so the group has write permissions: sudo chmod -R 2775 /home/username/path/to/uploads 4. Then try the script again. See if that works. Adam -- Nephtali: A simple, flexible, fast, and security-focused PHP framework http://nephtaliproject.com Thanks - The directory is output_files, which is a subdirectory of /var/www I'm getting a message invalid owner on the command chown Apache output_files. Also with the -R option, and with apache as the owner, also with the chgrp. All these commands are run as root.. Help and advice please. Ethan Hi Ethan, I might be missing something. Did you set up the user Apache? On a standard install for Debian (using apt-get), apache is usually set up as the user/group www-data: http://wiki.debian.org/Apache http://wiki.debian.org/ApacheThe root user typically owns the /var/www directory. I usually set up virtual hosts within one of the other accounts and then change the group on a directory outside of the public directory specifically set aside for uploads and run the commands I sent. However, in the case of your example, I believe you can just run the 2 commands I sent on the /var/www/output_files directory and you should be able to write the files. sudo chgrp -R www-data /var/www/output_files sudo chmod -R 2775 /var/www/output_files Hope this helps, and sorry if I misunderstood something in your configuration or troubleshooting.

Some whitespace (space or new line, for example) before that first ?php line could cause the headers to send and the sessions headers to fail (headers already sent error) which would give you the problems you're seeing now. Also, some editors have issues with the BOM (byte order marker) which could cause white-space to be perceived where there is none. If you are sure there isn't any, then try saving the script with a different character encoding to test if it is the BOM causing problems. -- Thanks, Ash http://www.ashleysheridan.co.uk
[PHP] is there a static constructor?
All,
I want to build a config file class that gets called statically. Is
there such a thing as a static constructor? Example:
class Daz_Config {
public static function load() {
...
}
public static function get($key) {
self :: load();
...
}
}
Daz_Config :: get('myvalue');
I want to call the load function when the class is used for the first
time. If no code ever calls Daz_Config :: get(...) then I never want
to invoke load() but if it does get called, I only want to call load()
once before the class is used further.
Anyone know how to do this with calling load() at the top of all the
other functions and writing a load() function that exits early if
already loaded?

Re: [PHP] is there a static constructor?
There is such thing, but its not called static constructor, its called
singleton pattern
class SingletonA
{
public static instance;
public SingletonA(){}
public static function getInstancce()
{
if(self::instance != null)
{
return self::instanc;
}
return new SingletonA();
}
}

The concept doesn't really make sense - a class that never gets
instantiated never gets constructed, hence no static constructor (nor
a static destructor). You'll have to call your constructor function
at the top of the static methods you'll be using - just check inside
the constructor if it's been called before or not.
