Is there a possibility with the future release of PHP to add extension in a easier manner. For every feature client wants there is a recompile involved. Wouldn't this be much easier if we just compile the appropriate library and just point the directory through php.ini. In that way most of the hosting provider would have update to date version. I also like features of gefionsoftware's LiteWebServer wherein they provide an admin screen and it allows us to update to the latest version without pain. Here I am talking about both upgrading to latest version as well as adding extensions. Have a great day.

?php print img alt='$title' border=0 width= '103' heigth = '70'

Thanks again.
I should do coding the whole page I gues ;-)
First of all some things to mention about:
1. Better store only filenames in the database and leave
the images in the directory, cause you have to copy then
to a location anyway to get it by an browser
2. Use an array of $image[] instead of numbering them
like $image1, $image2, ... (you have to use eval to
work with the numbers or have to write the code more
than once !)
Ok here it goes:
?php
// guess you have JPEG images
// --
$nr = 1;// start numbering your images
$maxsize = 150; // maximum size in one direction
// ---
while($nr = 9) {
$img = @imagecreatefromjpeg ($folder/$image[$nr]); // try to open
if (!$im) {
echo ERROR loading image $folder/$image[$nr] ;
exit 1;
} else {
$imagehw = GetImageSize($img);
$w = $imagehw; // width
$h = $imagehw; // height
// prevent division by zero
if (($h ==0) || ($w==0)) exit;
// get new size according to max size
if ($h$w) {
$new_h = $maxsize; // new height
$new_w = (int) (($maxsize * $w) / $h); // casting to int !
} else {
$new_w = $maxsize; // new width
$new_h = (int) (($maxsize * $h) / $w); // casting to int !
}
// build dummy image
$thumb = imagecreate ($new_w, $new_h);
// resize old image
ImageCopyResized($thumb,$img,0,0,0,0,$new_w,$new_h,$w,$h);
// maybe use tempname() to generate a temporary file name or
// create name of thumbnail file like: *.jpg == *.png
$tumbnail=substr($image[$nr],0,strrpos($image[$nr],.))..png;
// save png image to same directory as jpg
@imagepng ($thumb,$folder/$tumbnail); // hope we could write
// leave the temporary data ...
ImageDestroy($img);
ImageDestroy($thumb);
// finished work
// ---
// show image
echo img alt=\$title\ border=\0\ width=\$new_w\ .
heigth=\$new_h\ src=\$folder/$tumbnail\ ;
}
$nr++; // next image
}
?
maybe there might better ways but thats just a fast hack to work ...

[PHP] Re: restricting acces to files
Shams schrieb:
Hi,
i've written a secure PHP login script which will allow users to login to a
directory such as this:
smezone.com/members/index.php
however, how do I restrict people from accessing HTML files in that
directory (which they can easily do so by typing the URL into their
browser), such as:
smezone.com/members/document1.html
?
Since its a regular HTML files (and we have lots), I can't check whether the
user has a valid session as I would do in a PHP file.
if you are using linux apache ... just use a .htaccess file like the one below
AuthUserFile /usr/home/.htpasswd
AuthName Secret Area
AuthType Basic
FilesMatch \.(gif|jpe?g|png|htm|html)$
require valid-user
/FilesMatch
with this you restrict access only to users listet in the /usr/home/.htpasswd
files which look like
user1:668c1d6Hc6yCg
test:85FRBo8cHrAZc
the code after : is a MD5 key
the FilesMatch mean that all files ending with .gif,.html,.. is restricted and
.php is not.
in a php file you now can read the authentications from a user and compare it
with the /usr/home/.htpasswd entrys.
?php
...
if (!isset($PHP_AUTH_USER)) {
// $PHP_AUTH_USER is empty ... no login
header('WWW-Authenticate: Basic realm=My Private Stuff');
header('HTTP/1.0 401 Unauthorized');
echo 'Authorization Required.';
exit;
}
// If not empty, check authentication ...
else {
if ($PHP_AUTH_USER==$username $PHP_AUTH_PW==$mypasswd) {
echo PYour Login is OK;
?
...
?php
} else {
echo Pwrong login !;
}
}
?
note that the the /usr/home/.htpasswd file must include all usernames and
passwords as MD5. You can create a line of this file with:
?php
echo $username:.md5($mypasswd);
?
maybe you also can use mod_auth_db ... but this is apache specific so
take a look at http://httpd.apache.org/docs/mod/core.html

this test is OK with 4.3.0, but gives an error with 4.2.1.
It appears that paths are relative

- to the including script in 4.3.0
(but .. in include_path does not work).
I can't seem to be able to write something OK for both versions (except

safe_mode if off.
Any suggestion?
Failed opening '/inc/inc2.php'
looks like that he try an absolute path from the root / ... maybe try something
like
include('./inc/inc1.php');

instead. The include_path tells PHP only where to look for the file
. = same directory
.. = parent directory
if it is a single file or relativ path, but '/inc/inc2.php' is an absolute path
from the root ...

mhhh ... wait ... don't you wrote

wich means that testinclude.php includes inc/inc1.php
and inc/inc1.php includes inc/inc2.php ?
the include is like a copy of the code from
inc/inc1.php into testinclude.php so that in the
first sighth it might be correct to call inc/inc2.php
instead of inc2.php.
But maybe the parser of PHP 4.3.0 is rewritten so that it
now parse it bottom up. That means that first the inclusion
of inc/inc2.php into inc/inc1.php will happen which
fails cause its in the same directory.
... I tried it on my server ... all went Ok ... strange ...
insert something like into inc1.php and inc2.php:

echo br\n;
$folder=dir('inc');
// print out folder inc

echo $dateibr\n;

maybe did it head anywhere else or did it show something like

the FilesMatch mean that all files ending with .gif,.html,.. is restricted and

Right. I'm sorry, I didn't modify testinclude.php as you suggested, but
inc1.php. With a modified testinclude.php:
? include ('./inc/inc1.php'); ?
I get:
Failed opening './inc/inc1.php' for inclusion \
(include_path='.:..:/usr/local/php-4.3.0/lib/php')
Seems it doesn't like './' (inc/inc1.php is OK). I think that since
the name begins with '.', PHP tries to find a file in the working dir,
which is null (see below).
this is very strange cause I got it working with ./inc/inc1.php and with
inc/inc1.php ... /inc/inc1.php fail cause its searching the file in the
server root ... also inc1.php will fail cause it searches it in the
working dir of testinclude.php ... did you set
doc_root = /usr/local/www/htdocs
than maybe leave this blank !
insert something like into inc1.php and inc2.php:
?php
echo inc includedbr\n;
echo br\n;
$folder=dir('inc');
// print out folder inc
while($datei = $folder-read()) {
echo $dateibr\n;
}
$folder-close();
echo br\n;
?
Unfortunately, this gives nothing. I guess this is because pathnames of
files are relative to the working dir.
yes if the path not start with /
There are only two variables,
PATH and TZ in the environment of my Apache server, but nothing about a
working dir: cwd() returns an empty string, and so does `pwd` or `ls`.
Relative pathnames of included files are apparently resolved through a
special way, unless they begin with '.' or '..'. But this is not clearly
described in the documentation, and it's a bit confusing.
if a file is parsed, all include files a relativ to this parsed file.
with phpinfo() you could read the document root in the PHP Variables
section which might look like
PHP_SELF /phpinfo.php
_SERVER[DOCUMENT_ROOT] /usr/local/www/htdocs
...
_SERVER[SCRIPT_FILENAME] /usr/local/www/htdocs/phpinfo.php
_SERVER[SCRIPT_URI] http://www.yourdomain.com/phpinfo.php
...
_SERVER[PATH_TRANSLATED] /usr/local/www/htdocs/phpinfo.php
...
a . mean working dir and .. mean parent dir
echo exec('ls');
should print out not a empty string but
testinclude.php
and
echo exec('pwd');
should print /usr/local/www/htdocs/tests

you could include every page into a php script using
