[PHP] OO Programming - get practical
Hey all, I want to point something out to aspiring authors. The truth is, that few books and web pages out there show examples using OO methods. For example, the book I use as my primary reference has one chapter on OO PHP and that is it. The rest of the examples in the book are in regular functions. And the one example they give is used to create a web page, with the Title , KeyWords, Styles, Header, Menu... as the objects. So, I guess my point is that if people want to encourage use of OO programming, they need to use more examples in their books instead of what is "easy." Otherwise, if the reader doesn't "get" the one example, they don't have other examples to try. Furthermore, one cannot encourage people to think about how they can program using OO methods if they don't use such methods in their teaching of the subject matter. My 2 cents.

RE: [PHP] redirecting after login
why don't u do something like
if (!username)
{ you can not access this page
}
else
{
//page content
}
?
that's a quick fix but might be all you need to do..

Actually, yes - after a couple hours of playing around with the login and finally getting the Meta tags to work for me, I found that if the person were to simply type in the URL of the protected page, they would have full access. Right now I'm playing with sessions and global sessions to try and correct this problem. Although its not working as well as I had hoped. Basically the plan is for all users to goto Page 1 - the login page, and then be re-directed to their proper destination - Page 2. But, if a clever bad person were to simply type in the URL to Page 2 they could have access to the database and run amuck. So I added a line checking to see if the session from Page 1 is registered, if not, goto Page 1. That part works - what doesn't work is after they login to Page 1, the redirect sends them to Page 2 and right back to Page 1 because the global session isn't staying registered.

Okay, I removed that line and I no longer get the invalid File-Handle

Re: [PHP] Re: MySQL - PHP combined log
Thanks, but all these "methods" require modification of the scripts already on the server, and it won't ensure any new script being written by a user on my system to comply. Are you all saying that there are no logs kept by default of errors generated on php/mysql pages at all unless specifically coded? Wouldn't it be possible then in future PHP releases to have a "set_error_logging" directive in the php.ini file that will automatically run a wrapper function on all mysql_query() functions to do this kind of thing? How are people out there managing the scripts/script errors caused by users on their systems? Or is it a case of "handling the crisis when it happens"? You see, as administrator, I need to be able to quickly see who are coding in such a way as to leave security holes, or even worse, cause the server to crash due to poor coding. There are almost 1000 individual php files on my server, and it wouldn't be possible for me to scrutinize all of them to make sure they are OK. Are there any admins out there that have policies about scripting practices on their systems; ie, checking a script from a user before it is allowed to be uploaded etc?

That error indicates that fopen failed to open the requested file. Given
that the URL works fine in a browser, is it possible that your php is not
configured to do remote fopen? Check the setting of allow_url_fopen in
phpinfo()
It is a good idea to test the result of such calls before trying to use
the result:
fopen('Whatever') or exit('Couldn't get it, Boss!');
or
if(fopen('whatever') {
do good things;

Telnet is port 23, and the protocol is more complicated than you might
think. Perhaps you could look into using 'expect' (a unix utility) to
control your telnet session. That might bring you less heartache in the
long run.

Tens of thousands can start to become a problem. Look at the distribution of your file names and come up with a hashing mechanism. For instance, if your filenames are numbers, create subdirectories 0/ 1/ 2/ 3/ 4/ etc., and place the files based on their final digit. miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You can't.
If you want to do a post, either construct the request yourself, use one
of the many free classes created to do so, or use the cURL library.

As one other poster has mentioned, this is not really a PHP issue, but more of an OS one. IMHO, anytime you are dealing with a group of files that numbers more than say, 200 or so, it's worth it to split them out in seperate directories. I would suggest some sort of one or two level hash, based on the filenames. (Forget just splitting out the thumbnails, because if you really expect the number to double in the future you'll be glad you spent the extra time to put the hash into place.) If your names are sufficiently different, I would suggest hashing the directories based on the first two characters of the filename. For example, lets say you have two jpgs called: joejohnson.jpg tomsmith.jpg Place them in directories like so: /images/j/o/joejohnson.jpg /images/t/o/tomsmith.jpg This is similar to how a lot of mail delivery agents can be configured to deliver mail to a host with a lot of different users. If for some reason the filenames tend to begin with the same characters, then work backward for the hash. For example, I work at a real estate company and the photos for our listings are named off the listing number. Most of the time these numbers are in the same range, so we use the LAST two digits of the number. For example: 2450067.jpg 2450256.jpg go in /images/6/7/2450067.jpg /images/5/6/2450256.jpg Anyway, with a hash you have a definite algorithm to figure out where a file should be placed, and later where it should be retrieved.

The comma isn't actually for concatenation. The net effect is the same in
this case, but a very different thing is happening.
echo "hello " , "there";
Here 'echo' is printing two separate arguments. First it is printing
"hello " and then it is printing "there".
echo "hello " . "there";
Here the strings are concatenated to form a single string ("hello there")
and then this is processed by echo which prints it out.
The effects are the same, as I said, but it's important to realize why
they're very different ways of getting that effect.

RE: [PHP] redirecting after login
Hi. Since I haven't used meta tags for years now (don't like them:) I
can't help you there, but instead, here's a typical login/redirect PHP
page of mine. As you can see, it doesn't matter if the login form is at
the bottom of the page, or even if it's after an included header file as
long the form points to $PHP_SELF:
session_start();
if ($username && $pass)
{
$db_conn = mysql_connect("localhost", "admin", "password");
mysql_select_db("db_name", $db_conn);
$query = "SELECT * FROM table_name WHERE username = '$username'
AND password = password('$pass')";
$result = mysql_query($query, $db_conn);
if (mysql_num_rows($result) > 0)
{
$row = mysql_fetch_array($result);
if ($row['devlevel'] == '2')
{
$valid_admin = $row['devfirst'];
session_register("valid_admin");
header("Location: ../admin/index.php");
exit;
}
else if ($row['devlevel'] == '1')
{
$valid_user = $row['devid'];
session_register("valid_user");
header("Location: index.php");
exit;
}
else
{
header("Location: ../jumpto.php?fetch=devent");
exit;
}
}
else
{
header("Location: ../jumpto.php?fetch=devent");
exit;
}
}
else
{
header("Location: ../jumpto.php?fetch=devent");
exit;
}
Like this, I can diferenciate the users by fetching the "devlevel"
number from the same DB that the user was authenticated from.

That error indicates that fopen failed to open the requested file. Given
that the URL works fine in a browser, is it possible that your php is not
configured to do remote fopen? Check the setting of allow_url_fopen in
phpinfo()
It is a good idea to test the result of such calls before trying to use
the result:
fopen('Whatever') or exit('Couldn't get it, Boss!');
or
if(fopen('whatever') {
do good things;
}else{
bleat vigorously;
}

Not sure about the comma, but the {braces} are easy. They help separate the
$vars from other stuff in the string.
Example:
It's a good habbit to get into, and has saved my arse on a few occasions,
although the above example isn't a good one.

Re: [PHP] PHP Security Advisory: Vulnerability in PHP versions4.2.0 and 4.2.1
Greg, Your attitude stinks. PHP is a FREE scripting language. Think about the amount of money you are probably charging hosting clients, or charging in web or programming services, or making in site revenue, or whatever way you 'commercially function' through PHP. The register globals 'imposition' IS more secure and encourages better coding practices... would you prefer they made the change now, or in 5 years when you have 100's more sites to fix. Better late than later. If you want something that will never have a bug, never have a security hole, performs perfectly from day 1, never has an upgrade/change, and will never change for the better, you are utterly dreaming! The difference in this case is that the PHP Group aren't emptying your wallet. Sorry to hear that you'll have to do some more upgrading, but I'd keep the complaining to yourself -- "you get what you pay for" springs to mind, but in the case of PHP, we get a whole lot more.

RE: [PHP] redirecting after login
using header() should work if you don't output anything before it. If you can restructure your code so that you can remove any output until after the header(), then that'd be the way to go. You said the meta refresh didn't work - did you get the syntax right? Since I don't use it much, it's one of those tags that takes me ages to get the syntax right (I could chuck it into a code repository somewhere, but I'm too lazy to do that...)

Re: [PHP] Newbie getting close, form submission
I pointed this out to you in my original post:
you mail() call should be:
mail($MailToAddress, $MailSubject, $Message, "From: $MailFromAddress");
not:
mail("$MailToAddress", "$MailSubject", "$Message", "From:
$MailFromAddress");
In other words, I don't think you should wrap plain $vars in double
quotes... it may be the cause of the problem, or it may just slow down PHP a
little when not needed.
For debugging, instead of sending the mail(), just do this:
echo "To: {$MailToAddress}\n";
echo "Subject: {$MailSubject}\n";
echo "Message: {$Message}\n";
echo "From: {$MailFromAddress}\n";
In otherwords, you should be looking to see if each $var you're sending to
the mail() function IS WHAT YOU EXPECT, once you're sure they're correct,
THEN you can pipe them back into a mail() call, and test.
Possibly mail() is not working on the server at all. A great way to test
that would be to create a SEPARATE SCRIPT which just has this:
The reason for creating a separate script is to ensure that you're only
testing the mail() function, not anything else.
You could also try turning your error reporting on to a higher level, which
may indicate the bug.

Subject: [PHP] Problem with Not displaying HTML if data not found
I am trying to develop a page that, in certain places, I only want it to
display the and s if data is found for a given field. For example,
if I only have an image for the first floorplan of a house, I do NOT have
an image for the second floorplan of a house, then show the first floorplan
image only.skip over that next row because the field in the db is empty.
The problem that I'm having is that the syntax that I've been using to
define "empty" in the db field does not always work. The code reads:
if ($result[FLRPLAN_2]<>" ") {
printf ("");
printf ("");
printf (" Second Floor Plan:
") ;
printf ("") ;
printf ("");
printf ("") ;
echo "'";
printf (" ") ;
printf (" ");
};
if ($result[FLRPLAN_3]<>" ") {;
printf ("");
printf ("
Third Floor Plan: ");
printf (" ");
printf (" ");
printf (" ");
printf ("");
echo "'";
printf (" ");
printf (" ");
};
I have tried:
1. if ($result[FLRPLAN_3]<>" ") {;
2. if ($result[FLRPLAN_3]<>"") {;
3. if ($result[FLRPLAN_3]<>'') {;
4. if ($result[FLRPLAN_3]<>' ') {;
5. if ($result[FLRPLAN_3]<>NULL) {;
and none seem to work correctly (i.e. blank field in db, but HTML row shows
up with missing image..or image is in db, but no HTML row shows up. If
it helps, each of the "image" fields are varchar(125)basically I just
have the name of the image file, and then a pointer to the web server
directory structure
Any ideas would be greatly appreciated. Thanks.

[PHP] redirecting after login
Hi, A site I'm working on requires a login screen where various individuals will log into the site and add information for their various departments. Rather than setup a different script for each department, I was hoping to create one script that would either accept or deny a login based on the username/password stored in a database, then based on the username/password - redirect the individuals browser to a URL. I've got the login part working perfectly, and I can turn the URL into a link on the page, but I'd rather have the script just automatically forward the person to the page they're login gives them access to. I've tried using header(), but since the redirection takes place about mid-script, it doesn't work. I've also tried using tag redirects, but those don't seem to accept the PHP/MySQL combo. Any ideas?

probably what you need is:

if ($table[bg] == "no") {
$bgcolour = imagecolorallocate($im,1,1,1);
$trans = imagecolortransparent ($im,$bgcolour);
}
else{
$bgcolour =
imagecolorallocate($im,hexdec(substr($table[bg],0,2)),hexdec(substr($table[bg],2,2)),hexdec(substr($table[bg],4,2)));
}
$fontcolour =
imagecolorallocate($im,hexdec(substr($table[fg],0,2)),hexdec(substr($table[fg],2,2)),hexdec(substr($table[fg],4,2)));

[PHP] Using fopen()/fread()/fscanf()
I think I'm pretty close to getting this right (maybe!), I've been reading

[PHP] number of files in a dir vs. performace
I'm using mysql to hold references to image files then served on my pages via PHP. I have typically a set of two files: thumb and a large original, on occasion there is also a variant inreasing the set to 3 per image currently I am holding all of the files in 1 directory since the DB can keep track of them, however their number has grown to over 400 at this point my issue is whether it would be worth it (performance wise) to split them into thumbs and works thus having 200+ files per directory as opposed to so many, I am expecting the number of images to double in the future.

It looks like you are using $table[bg] for 2 purposes
if it is 'no' it will not be a true hex value for the background
colour.

"r+" allows you to read and write... if that's what you wanted (I think it
is). Note that it will write over any data that is behind the location of
the file pointer (so write to the end of the file).

[PHP] Re: Traversing an appendable file
I was thinking it was obvious because otherwise I'd have just been using that and not even posted about the "a/a+". Using "a" works in the way that it is supposed to (it starts at the end), but what I wanted was to use append and then just append to anywhere in the file. Currently to get that done I use "file(filelocation);" and then just search that array for what I want. Once I find it I save the key and then concatenate what I want to that line. Then after I've done that I implode the array and "w" (write) that. This of course works perfectly, but once the file starts to get larger, I'm worried that it is going to become slow, so I was looking for a way to append (which now that I think about it, would do the same thing, only with less work on my part).

i'm tring to run the useradd command (under Solaris) to add a user to the
system so i don't have to continueously remote log in and also make it
easier for myself to add users to the system(s).. maybe popen isn't the best
option for this .. though i don't think fopen will be able to do what i need
it to do.. maybe playing around with sockets would be better?

If you are just checking the name/password against an existing list, then
you only need read. If you want to add something, then you need a
different mode.
However, I think you may be better off uing fopen, instead of popen, if
you are trying to do what I think you are. The documentation for fopen has
a comprehensive description of the modes available; note that w is kindof
destructive in the wrong context :-)

[PHP] does this mean ....
hi all,
I'm tring to make a script to prompt for a username & then a password for that user
onto the actual machine rather than just a web site...
now i've come across this this line in some documentation
if ( $File = popen( "$useradd_prog $useradd_name", "r" ) )
{
.
.
.
now to my actual question ..
does that "r" just mean read? and if so should that "r" be a "w" for write in order
for it to work?

>Not being an expert in php..i couldnt understand the vulnerability. >Can someone shed some light here. Very short explanation: Upgrade. Now! Longer one: If your web-site has *ANY* FORM tags on it, and you have PHP ready-and-waiting to process those FORMs, then somebody could manage to create a really icky FORM page and POST to your site and break in. Actually, even if you do *NOT* have the FORM tags, but you're "allowing" them in httpd.conf, and PHP is there, they could break in. Presumably the precise details of what you'd have to slam into the FORM to break in are simply too complex to fit into an Announcement of this nature. I imagine the Details could be dug out of Bugtrak and/or wherever the bug was first announced/discussed. Presumably PHP-Dev and e-matters would be good places to start digging for gory details. If Upgrading is impossible, *AND* you don't use FORMs with PHP in the first place (highly unlikely) than you could just "turn off" POST (forms) in your httpd.conf and nobody will be allowed to POST (send a form) anything to your web-site, and then PHP won't ever see the data, since Apache stopped them, and the bug wouldn't kick in.

The {} makes it *VERY* clear to PHP that $strName is a variable to be
"interpolated" into the string.
This Programmer has actually read the Documentation and believed the
warnings that some day just plain old $strName might not be enough.
The , simply gives more arguments to the echo construct.
You can echo as many things as you want, and they just get sent out one
after the other.

Use fsockopen() to "talk" to your *OTHER* PHP script waiting in a loop to do
the *real* work.
IE, have a *second* PHP file that runs on yet another socket to do the work.

You should be able to capture the output of http://php.net/exec or
http://php.net/popen and do whatever you want with it.
fsockopen will, however, almost certainly be faster/better if you have to do
a lot of these.
I think telnet is port 22, usually... Or maybe 23. SSH is the other one of
those, and I always forget.

You're simply looking at the old PHP. You did stop/start Apache, right?... Cuz the new PHP won't kick in until you do. If so, almost for sure your installation of the "new" PHP binary is not happening correctly. Watch carefully when you do "make install" to see where your new copies go.

The LIKE operator will cheerfully return 1 or 0, which you can "add up", or
in your case, "weight and add up" in your SELECT:
$query = "select 0 ";
# The 0 is a kind of 'yeast' to start off our summation of matches.
$words = explode(' ', $search);
while (list(,$word) = $words){
$word = trim($word);
if ($word){
$query .= " + article_keyword.weight * article_keyword.keyword like
'%$word%' ";
}
}
$query .= " as score ";
$query .= " from article_keyword, article_data ";
$query .= " where score > 0 ";
$query .= " and article_data.aid = article_keyword.aid ";

Just register it one time.

RE: [PHP] Formating datevariables...
Yeah .. the php function date shud do it .. if only the timestamp would be in the correct format. I've been wrestling with it too, best way to do it for me was using some substr() calles to extract year, month and day from it. anybody better ideas? -- Alle door mij verzonden email is careware.

Select TIMESTAMP(date_column) AS mydate
Then when you display it use the date function
DATE('mdY',mydate)

Heey Listers, I've got a small question. Does php provide any function to group a number like 3193576 into 3.193.576 ? Just reads easier when the hits for my website are being displayed ... Or if php doesn't have a function for it .. anybody any good suggestions on how to do it?

You can't do this in a php file... by the time it gets to this line, it's too late. According to the set_ini function on php.net, register_globals is only set-able in the ini file or in .htaccess.

RE: [PHP] Comma question
I remember from a previous post, the dot operator will create a temporary
string in memory, and then echo that out. The comma operator will just
output as it goes - ie. it doesn't create a temporary string.
As for Lee Doolan's reply:
echo "{$obj->strName[$i]}";
interesting - never thought of doing that, I alway's broke out of the quotes
to do object dereferencing. Should make my future code more readable I
think...

I figured that the comma was to concatenate but is was wondering if the

I have only seen it like ${var}...

Re: [PHP] Simple question I guess.
Okay im not sure i understand you- you want to create a page where it will suck an item out of a database, and use it to choose which item in a drop down menu should be selected?
