This only sets the display size of the image *after* the whole image
(whatever size it may be) is downloaded into the browser.
The original post mentions limiting the size of the images that will be
transferred. The way to do it would be to use either the 'builtin' php image
manipulation functions, or to call some command-line program from within php.
This would be probably be done at the time of the upload.

Hey
Does anybody know if its wise to use eval() ? I know Vbulletin uses it.. but
there is something about it I just cant digest.. it seems to be a very
powerfull function which can be very easily exploited... anyone else have
any thoughts?

Loading your templates into a database, pulling them out on every page
load and running eval() to run the code isn't the most efficient way to
do it.
Then running eval() inside a loop on that code isn't efficient either.
I think eval() is used this way by some people because they don't know
how to write files using php propely. So instead they just put it in a
database. You also completely miss out on getting the benefits of one of
the different php caching products.
For me a database is for storing data - not php code.
Vbulletin as an example of complete overuse of eval().

Hey,
I tend to agree with you. But what is the most effiecent way of using php
code in template files then? I am not going to move my templates to a
dbase.. thats for sure.

The point of templates is to seperate code from presentation and
content. Your template should only contain html/js, and your code should
be in the script that calls the template. Why not databases? That way
you achieve a proper 3 tier structure that's easy to maintain.

well for looping through the results of a sql query where you'd want to
print out some html -
to do that you could -
a include a file inside a loop
b run eval on some code from a database
c run a function
I find c to be the most efficient
eg
function thread($sql_arra0
{
echo 'name - '. $sql_array['name'] .';
}
then inside of loop
thread($sql_array);
works a lot quicker than the other two methods.
I don't see how you can avoid putting php code in templates because you
need to put $var in there some way so you can print out the variable. So
if it's in a database it needs some eval() done on it.
I really can't see the point in querying a database to pull out template
data. Templates usually don't change very often at all and querying a
database to pull out unchanged template data is waste of cpu and memory
resources.

You could html comment lines?? I tried this.. but it would only consider the
first and the last match of the ereg.. not the in-between ones :(

Hi everybody,
I've finally been able to read the e-mails sent by the little script I was
using.
The problem was the address where the script was trying to send the e-mail.
Instead of a *normal* e-mail (i.e. [EMAIL PROTECTED]) like was written in
the book I wrote my *local* address (mitch@localhost) and it worked :-)
I got the e-mail both in the terminal and using the application "Mail" where
I configured an UNIX account.
I am still not able to let the script send e-mails to normal e-mail
addresses, but I think I will now install "postfix" which, as I read, should
be easier to use and configure than "sendmail".
Thanks to you all for the tips and resources you gave me.
Bye,
Michael

I would like to checkout some xml and xsl files from cvs and transform them
using php script. The second part seems easy, but how can I checkout cvs
module from php script. I tried system("cvs -d /home/cvs checkout myModule")
but there was no result. There was no error either. I am shure it is quite
easy. Please, give me a hint.

Good morning everyone,
I'm trying to adapt existing php code that uses a while loop to scan content
for a url pattern, take the matches and add link tags (<a>) around them so
the url with be made into "hot links. Simple enough right? Nevertheless, I
seem to be having trouble with urls that have question marks in them.
Here is the existing code that works - except with question marks:
********************
$content = "http://www.globalhealth.org/text.php3?id=151
adjfladjfajdfkladfjl;kadjf
jlkadjflkajdflkj jadklfjalkdjfl;df jalkdfj;ldafj";
$pattern = "http://([\/~_\.0-9A-Za-z#&=-]+)";
while(ereg($pattern, $content, $match)){
$http_old = $match[0];
$http = "dubdubdub" . $match[1] . $match[2];
$url = "<A HREF=\"javascript:externalURL('$http')\";>$http</A>";
$content = ereg_replace($http_old, $url, $content);
};
$content = ereg_replace("dubdubdub", "http://";, $content);
print $content;
******************
Here's the same code with the question mark in the pattern variable. When I
add the question mark and test the page, my browsers just "hang". Escaping
the question mark doesn't seem to help (and I also read that escapes aren't
necessary between square brackets]:
$content = "http://www.globalhealth.org/text.php3?id=151
adjfladjfajdfkladfjl;kadjf
jlkadjflkajdflkj jadklfjalkdjfl;df jalkdfj;ldafj";
$pattern = "http://([\/~_\.0-9A-Za-z#&=?-]+)";
while(ereg($pattern, $content, $match)){
$http_old = $match[0];
$http = "dubdubdub" . $match[1] . $match[2];
$url = "<A HREF=\"javascript:externalURL('$http')\";>$http</A>";
$content = ereg_replace($http_old, $url, $content);
};
$content = ereg_replace("dubdubdub", "http://";, $content);
print $content;
*************************
In an attempt to find the problem, I did a test with the following code and
received the result I want - which leads me to believe the problem is
possibly with the while loop or the ereg_replace??
$content = "http://www.globalhealth.org/text.php3?id=151
adjfladjfajdfkladfjl;kadjf
jlkadjflkajdflkj jadklfjalkdjfl;df jalkdfj;ldafj";
$pattern = "http://([/~_.0-9A-Za-z#&=?-]+)";
ereg($pattern, $content, $match);
print "<A HREF=\"javascript:externalURL('$match[0]')\";>$match[0]</A>";
******************
I'm completely confused. I have a feeling there is any easy answer and if I
wasn't so frustrated I'd be embarrassed to say that I've spent hours on
this...
Thanks in advance for your help, Shawna

Malte,
Thanks a lot. I was going through the File Upload
Functions in the manual and i think that's what they
were talking about too.
Now there's just one thing. I can run the upload
scripts and get the image for display too. But like i
mentioned, this is for a PenPal system, a database
based PenPal sysem.
Basically there has to be some connection between the
record entry by the user and the image. Which also be
required when this record is displayed, for the
corresponding image to be displayed. How migh that
work?
Thanks again,
T. Edison jr.

The best thing to do would be to store the filename (& path if necessary) of
the image in the corresponding record of the database.

ooh... i dont know if i understood you correctly..but if i did, you simply
have to insert the location of the file in the users tupel like..
UserID Name Bla Bla picture
001 John ... ... ./images/john.jpg
preferably i would only store the location when the user did upload an image
with an update query, so when fetching the information from your database,
you can check for empty location values... if you're working with mysql it
would be like...
while($my_array = mysql_fetch_array($result))
{
echo "Stuff about the User";
if($my_array[location])
{
echo "<img src=\"$my_array[location]\" width=\"100\"
height=\"100\">";
} else echo "<img src=\"standard.jpg\">
}
but as i said, i dont know if i really understood your question.. (im
german, you know *g*)

I'm trying to get gnupg (OpenPGP) working on my system, which is Solaris 2.6
on Sparc, with PHP 4.0.6 and Apache/Stronghold.
I have the program compiled, as it works at the command line. Here's what
works at the command line:
/usr/local/bin/gpg --encrypt -ao /usr/local/www/htdocs/777/crypted -r
'<[EMAIL PROTECTED]>'
/usr/local/etc/www/htdocs/777/plain_text_mesage.txt
If I type the above at the command line, when logged in as the user Apache
and PHP is running as (nobody), it encrypts the contents of the file
/usr/local/etc/www/htdocs/777/plain_text_mesage.txt and writes it to the
file /usr/local/www/htdocs/777/crypted, which is what I want. (The
directory /usr/local/www/htdocs/777/ is "chmod 777", and PHP can write a
file in that directory.)
I've tried everything I can think of, but it looks like a command from PHP
is not working like it is at the command line.
I've tried:
system("/usr/local/bin/gpg --encrypt -ao
/usr/local/www/htdocs/777/crypted -r '<[EMAIL PROTECTED]>'
/usr/local/etc/www/htdocs/777/plain_text_mesage.txt");
passthru("/usr/local/bin/gpg --encrypt -ao
/usr/local/www/htdocs/777/crypted -r '<[EMAIL PROTECTED]>'
/usr/local/etc/www/htdocs/777/plain_text_mesage.txt");
exec("/usr/local/bin/gpg --encrypt -ao /usr/local/www/htdocs/777/crypted -r
'<[EMAIL PROTECTED]>'
/usr/local/etc/www/htdocs/777/plain_text_mesage.txt");
$command= `(/usr/local/bin/gpg --encrypt -ao
/usr/local/www/htdocs/777/crypted -r '<[EMAIL PROTECTED]>'
/usr/local/etc/www/htdocs/777/plain_text_mesage.txt`;
(Each of the above 4 lines of code probably word wrapped in this email, and
the last line contains backtics, not single quotes.)
So, I'm stumped. I was following the basics of the article at:

Check out the relevant chapter in the manual for the db that you're using.
Some dbs have a function returning the number of rows.
If you're using MySQL then mysql_num_rows() is what you want.

Hi!
You can find the PHP !manual! at http://www.php.net/manual
Try searching for open , opendir, readdir .. or whatever other function
you're looking for.
If that doesn't give you an answer straight away, you could go back to the
manual index and find the appropriate category, like Filesystem functions.
About question 3, I think it depends on what you want, but it's possible to
get the access time of a file; also see chapter Filesystem functions.
Also search the manual for preg (if you didn't figure yet) to see how to
use perl style regular expressions.

Hi,
i am fiddling with a script and need to change a while-loop from running on
mysql_fetch_array to a "normal" array?
ie - i have:
while($myrow=mysql_fetch_array($result)) { etc...
But i want the loop to run with an array i created earlier ($anotherarray =
[key1] => value1, [key2] => value2).
How would i do that? Does the loop behave the same way - running until the
array is out of data?
Thanks!

Hey List-
Banging my head again the wall with this one. One of our developers was
trying to get some session stuff to work and he couldn't and asked me to look
into it.
I have a script that contains the following (the sessions.php href reference
is the same script accept it calls this one):
_____________________________
session_start();
if (!isset($HTTP_SESSION_VARS[count])) {
$HTTP_SESSION_VARS[count] = 0;
}
else {
$HTTP_SESSION_VARS[count]++;
}
//Print the counter
echo "Counter is now: $HTTP_SESSION_VARS[count];\n<br>\n";
echo "Let's go to another <a href=\"sessions.php\">page</a>...<br><br>";
_______________________________
On my box at home running PHP 4.0.6 it works great.
On the work server running PHP 4.0.6 it doesn't work. Just keeps setting
count to 0.
The work box is running Apache 1.3.20 with the following compile options:
'./configure' '--with-apxs' '--with-config-file-path=/etc/php'
'--with-openssl=/usr/local/openssl' '--with-zlib' '--with-bz2'
'--with-pspell' '--enable-ftp' '--enable-gd' '--with-imap' '--with-mcrypt'
'--with-mhash' '--with-mysql=/usr/local/mysql'
The home box is running Apache 1.3.22 with the following compile options:
'./configure' '--with-apxs' '--with-config-file-path=/etc/php'
'--with-openssl=/usr/local/openssl' '--with-zlib' '--with-bz2'
'--with-mysql=/usr/local/mysql' '--with-mcrypt' '--with-mhash'
'--disable-xml' '--enable-ftp' '--with-gettext' '--with-pspell'
'--enable-inline-optimization'
The only major difference that I could find in the php.ini file is that at
home I have register globals off and at work they are on?
Even with register globals on, you can still use the $HTTP_*_VARS, right?
The sessionID cookie is getting put into my browser, I checked so the
"session" is starting correctly, just not retaining the variable.
Any ideas anyone?
Thanks list.
Henrik

I am really baffled by this problem. I have tried so many things to get
this working but to no avail. Here is the
actual code:
function verify_user($username, $password){
$conn = mysql_connect($db_host, $db_user, $db_pass) or
die("Error while connecting to Database System.");
$select_db = mysql_select_db($db_name) or
die("Error could not select the database");
$query = "SELECT FROM users WHERE username='$username'";
$result = mysql_query($query) or
die("Unable to get query");
$rows = mysql_fetch_array($result);
$password = md5($password);
if($rows["password"] == $password){
print "You have been verified as $username.<br>";
print "Registering your session.<br>";
}
else{
print "Error: Bad username or password.<br>";
print "Please go <a href=\"/?page=admin&step=1\">back</a>";
}
}
Anyways the problem is I cannot get it to even get to the database. It
works when I try to connect in the actual code before I call this function.
Like for example in index.php
$conn = mysql_connect($db_host, $db_user, $db_pass) or
die("Error while connecting to Database System.");
$select_db = mysql_select_db($db_name) or
die("Error could not select the database");
verify_user($username, $pass);
But when I do it that way it won't let me run a query right. I am so
baffled. Any input would be appreciated. Thanks.

Remember the idea of the "scope" of a variable? (if not, please RTFM)
Where do the values of $db_host, $db_user, etc come from?
They are not in the argument list for verify_user().

they are in the same script outside the function.
all the admin functions reside in a admin_func.php
with the $db_host, etc, etc variables assigned before it.

Just as DL Neil implied, your variables are outside the scope of the
function. set them global within your function.

I am trying to basically copy data from one database to another and am
wondering if it is possible to have more than one database open at a time.
So for example, I want to do something like this but am wondering if there
is a better way:
$dbcon = mysql_connect($db_server, $db_user, $db_passwd); //Make source
connection
mysql_select_db($db_name);
//Select source db
$source_result = mysql_query("SELECT * FROM users"); //Select all
info from users table
while ($row_cat = mysql_fetch_array($result)){
//Loop through and insert into new db
//Insert into new database
}
So where I have "Insert into new database" this is where I want to take some
of the information from the source and insert into the new database (which
uses a different user name and password as well).
Any help would be greatly appreciated :)

It;'s entirely possible. Most database-related functions can take an
optional link identifier parameter. You didn't use it, and in that case,
database operations default to the last opened database connection. You
can however do something like:
$dblink1=mysql_connect($server1,$user1,$password1);
$dblink2=mysql_connect($server2,$user2,$password2);
mysql_select_db($database_1,$dblink1); //for link 1
mysql_select_db($dblink2,$dblink2); //for link 2
$result1=mysql_query("SELECT * from whatever",$dblink1);
while ($row=mysql_fetch_array($result1)){
$query2="insert into secondtable values ".
$row["id"].",".$row["whatever"];
$result2=mysql_query($query2,$dblink2); //insert on database 2
}

Hi,
If Call-time pass-by-reference has deprecated
so long ago, why are the instructions on how
to do it still in the manual?
http://www.php.net/manual/en/html/functions.arguments.html#functions.arguments.by-reference
At least it should point out that it has been
deprecated.
