Re: [PHP] Need Help.
Hi Girish, You can save the SEssion id in a Cookie to make it available over requests and over days too. If you use Sessions stored on DB, you can get more security, when the SEssion Cookie is stored Encrypted. Other Option is to send the Session id, most know as PHPSESSIONID, as GET Variable.

There's actually a bug in it (my huge query) though not significant, I'm planning to just break it up into several smaller queries and use php to do the hard work since that's easier to read and performance isn't an issue (run by server twice a month to generate a png image, never run by user). But yeah - the stuff in the documentation where prepared statements don't work is pretty obscure stuff.

Hi Girish, 1. You cannot modify the browser Back button (any thing on the client's computer for that matter). 2. I strongly oppose the use of Cookies for tracking the user login, due to security reasons. Cookies are saved on the client's computer and he/she can easily modify the information present.

You're really opening a big can of worms here, but it'll be a good
adventure. Just keep at it and try reading some real books on the
subject.
If you include a file, all of those variables are magically in the
current scope. So when you include config.php inside your index.php,
you can use $dbconnect directly.
Use $this-> when you are inside a class using a dynamic call on a
method or property of that class.
class Foo {
protected $bar;
public function __construct() {
$this->bar = 'wee';
}
public function setBar($value) {
$this->bar = $value;
}
}
Inside the class you would use this-> to reference bar or call any of
that classes methods/props. Outside you would use it like this:
$foo = new Foo;
$foo->setBar('blah');
If you haven't used globals yet, please do not feel compelled to do so
now. There are all sorts of ways of dealing with passing around your
application state. Globals can be used by a skilled programmer of
course, but I'd shy away from them.
I'd also recommend reading some of these pages:
http://www.php.net/manual/en/language.variables.scope.php

Check out > Yahoo! Buzz. http://in.buzz.yahoo.com/ The main thing to be aware of would be 'email header injection.' Do not allow returns/newlines in any of the mail header fields you populate from user input. Also require a valid email address and verify that it has a valid domain name. Next up would just be the annoyance of a client receiving tons of spam messages. There are a lot of automated programs crawling the web just filling out every form it finds looking for vulns to exploit. Even if your form has no holes in it, the client will still get all of this unwanted junk from the automated tests.

The :: is used to access static methods of a class. Static methods can
be used without creating an instance of the class because they dont
use any of the classes member variables.
For example say you have a class with a function for calculating the
area of a rectangle:
class SomeMathFunctions {
public function calculateRectangle($width, $height) {
return $width*$height;
}
}
To use this function you would need to first create an instance of the
class then call the method using the normal -> :
$funcs = new SomeMathFunctions();
$area = $funcs->calculateRectange(10,15);
But if you create the function as static by using " public static
function calculateRectangle($width, $height) { "
then you can access the method by using just 1 call:
$area = SomeMathFunctions::calculateRectange(10,15);
So for creating utility functions its better to use static methods
since you dont get the overhead of creating a new instance of the
class.

Re: [PHP] MySql Injection advice
you can do that with IPs because it is an implementation of an integer. look: I take a integer value: 2130706433 express it as binary: 1110001 now I have to look it as bytes: 1110 0001 express the bytes as decimals: 127 0 0 1 does this number means anything to you? IPv4 are just simples integer values stored as bytes Here you have another example 192.168.0.1 192 = 1100 168 = 10101000 0 = 1 = 0001 all together is 110010101001 which my calc says it is 3232235521 (it doesn't understand the negative implementation of numbers) Telephone numbers are quite different, but in sort way they similars 8765-4321 can be the same as +0871187654321 (if you are in the same are code) I think the solution should be based in your audience target.

Re: [PHP] Scope of Variables and use of global and this->var
do you need to use global?
IMO you should use just 1 global variable, thats is what I call "entry point"
My scripts looks like...
require_once 'loader.php';
Loader::registerAutoload();
$foo = new Foo();
$foo->doStuff();
This way you can develop faster and do maintenance better avoiding
problems with third-party.
Here you have some rules for remember how to access
you want a $var from outside and you are outside an object or
function? => use the $var
you want a $var from outside you are inside an object or function? =>
global $var o $GLOBALS['vars'] (better to pass it as arg)
you want a $var from an object and you are inside the same object? =>
use $this->var (better $this->getVar() )
you want a $var from an object and you are inside other object? => use
$object->getVar() or Class::getVar()
It is a good practice to declare the object members as "protected" and
provide s/getters for each member (when your design allow it). Also
you can overload by using the __get, __set and __call
It is really easy to make an "automagic" object
Class AutoMagic
{
protected $_vars = array();
public/*mixed*/
function __get(/*string*/$name)
{
return isset( $this->{ $name } ) ? $this->_vars[
strtolower($name) ] : null;
}
public/*mixed*/
function __set(/*string*/$name,/*mixed*/$value)
{
return $this->_vars[ strtolower($name) ] = $value;
}
public/*boolean*/
function __isset(/*string*/$name)
{
return array_key_exists( strtolower($name), $this->_vars );
}
public/*void*/
function __unset(/*string*/$name)
{
if( isset( $this->{ $name } ))
unset( $this->_vars[ strtolower($name) ] );
}
public/*mixed*/
function __call(/*string*/$method,array $args)
{
$type = strtolower( substr( $method, 0, 3 ) );
$property = substr( $method, 3 );
switch( $type )
{
case 'get':
return $this->{ $property };
case 'set':
if( !array_key_exists(0, $args) )
trigger_error( 'Bad call in ' .
get_class($this) . '::' . $method
.'. Method needs an argument' );
return $this->{ $property } = $args[0];
case 'has':
return isset( $this->{ $property } );
case 'del':
unset( $this->{ $property } );
return;
}
trigger_error( 'Bad call in ' . get_class($this) . '::' .
$method );
}

[PHP] Weird domain seting in setcookie()
Hello,
on two websites I have encountered that cookies are not working properly
and are accesibel from other subdomains which I do not want. The line
is:
setcookie('AdminOnCrack', $drug, $timeout, '/', $_SERVER['HTTP_HOST']);
but the "domain" is always prefixed with a ".".
OK, now I have tested it using:
setcookie('AdminOnCrack', $drug, $timeout, '/', 'myspace.tdwave.net');
but with the same problem. I do not want that the cookies are available
in <*.myspace.tdwave.net>.
Any suggestions?
Thanks, Greetings and nice Day/Evening

[PHP] How to set find pathes for PHP CLI?
I have many scripts that I need execute with PHP CLI. They are located in a few directories. I don't want to write full path to script every time when I start it. Therefore I've added this paths to the PATH environment variable. But PHP don't find my scripts. How could i set paths on which PHP would find my script when i call e.g. "php -f my_script.php"? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] [GD] Image errors
Hi to all
I get a problem processing an image with GD libraries.
This is my function
public function showPicture($id) {
header('Content-type: image/jpeg');
$mime = mime_content_type($this->updir.$id.'.png');
$type = explode('/',$mime);
$type = 'imagecreatefrom'.$type[1];
$immagine = $tipo($this->updir.$id.'.png');
imagejpeg($immagine,null,100);
imagedestroy($immagine);
}
If i commentize the "header" function i get a lot of strange simbols
(such as the code of a jpeg image!) but no errors.
The result of this code is a blank page. In Firefox the title sets to
"picture.php (JPEG image)" and if i right-click it and click on
"Proprieties" i get "0px × 0px (resized as 315px × 19px)".
P.S.: I get the same result when I write $immagine =
imagecreatefromjpeg(...)
(Sorry for my english)
Thanks in advance,
Alfio.

Hi Bob, Am 2009-07-14 11:46:16, schrieb Bob McConnell: > In Firefox 3.0 under Tools->Options->Privacy, uncheck "Accept > third-party cookies". What has this to do with the Webbrowser? In the PHP manual it is written: [ url 'http://de.php.net/manual/en/function.setcookie.php' ] domain The domain that the cookie is available. To make the cookie available on all subdomains of example.com then you'd set it to '.example.com'. The . is not required but makes it compatible with more browsers. Setting it to www.example.com will make the cookie only available in the www subdomain. Refer to tail matching in the » spec for details. This mean, if I wan to have the COOKIE available in the subdomains foo.myspace.tdwave.net bar.myspace.tdwave.net baz.myspace.tdwave.net I have to use the domain ".myspace.tdwave.net" with a preceding DOT. But this is not what I want because I want to have the COOKIE only available in myspace.tdwave.net so, I have set the the domain explicit to "myspace.tdwave.net" which should register the cookie as it is according to the PHP manual or not?

Bottom post ;)
$type = explode('/',$mime);
$type = 'imagecreatefrom'.$type[1];
$immagine = $tipo($this->updir.$id.'.png');
imagejpeg($immagine,null,100);
imagedestroy($immagine);
I'm not sure you understood what I meant. line 2 above $type is assigned
to the string 'imagecreatefrom'.$type[1];
Now I assume that was to be used later in some sort of eval() statement,
but its never called again, so the line really does nothing.

Mmmm, No
$type = explode('/',$mime); # type is array
$type = 'imagecreatefrom'.$type[1]; # type is a string
He is actually re-assigning the var ussing the content of the var.
Sounds crazy, but I use this method a lot, it helps to keep the scope clean.

RE: [PHP] Doubts concerning a general Insert method
Ok... according to the above posts, I've started to create my generic CRUD class however, I'm wondering: Any of you have already used a DAO design pattern in conjunction with a CRUD generic class? Know that I'm trying to create a generic CRUD class on a DAO Design pattern, it seems that it makes no sense at all. Is there an advantage on doing this? My thought: On a "insert to database" scenario for example: Without the CRUD generic class: to do an insert, we instantiate a DAO class and then call the insert method. Nothing more. Done. With the CRUD generic class: maybe we will have less code on the DAO site but, at the end, to insert a record, we still need to instantiate a DAO and call a insert method SO... I see not big advantage on using both... Can I have your advice on this please? Thanks, Márcio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It's not crazy, I do it a lot, but he *does nothing with it* after that,
and the scope of the variable is limited to the function.

Re: [PHP] [GD] Image errors
Why are you ussing GD?
All you need is output the image to the browser?
try this... I didn't test/run this code, but it may work...
public function showPicture( $id ) {
header('Content-type:' . mime_content_type( $this->updir . $id .
'.png' ) );
readfile( $this->updir . $id . '.png' );
}
hey, look, just 2 lines!

[PHP] Pattern Matching
Hello Guys, I have a question related to pattern matching and wildcards. This is the scenario. I have friendly urls on my website. So retrive their path as arguments for every page. so for example if I have www.xx.com/contact/me my args array will be args( 0 => contact, 1 => me ) My requirement is to change the page title on the fly with specific patterns, so what I do is define a look up table with these columns. path, pageTitle contact/me - Contact US perfect match would be easy because I can exactly look for what I want. It becomes tricky when I introduce wild cards like contact/* for example. It could also be contact/me/* How would I match patterns for this kind of relative matches.? Any ideas anyone? Thanks, V

Well, are you opposed to using Javascript?
//javascript function
//You could make a hidden form field to store the value of the letter
selected.
//Perform your query and search only for the letter if it isn't blank.
//Print out all your letters
//Have the links call a javascript function that updates the letter selected
and resubmits the form to perform your new query
$letter
Something like that. I haven't tested any of that code just typed it up real
quick to give you an idea of one way to possibly do it.
Hope that helps.

Why are you setting the value of $name to an array? If you try to echo
$name after this statement (as you are below), PHP will echo the word
"Array".

If the list of restaurants is very long, I wouldn't store it in a
session variable. It is the same for every person who visits your
site, so there is little use storing separate redundant copies in
session scope where it will needlessly fill up disk space and/or
memory.
As far as the query is concerned, you could do this:
I would also consider whether you really need the keyword DISTINCT in
the query. In a properly normalized table, name should probably
already be distinct (and constrained by a UNIQUE index on that
column).

Forms are notoriously easy to compromise for sending spam and corrupting web sites. A program I have used in the past is FormMail by http://www.tectite.com. There are many other FormMail programs available by the same name - this one is well documented and easy to set up. It doesn't provide as much database security as you may want, but it does a good job of hiding email and preventing cross-site scripting attacks.

[PHP] General good practice question about functions directory location
Most of my scripts are written for use on shared hosts. I've generally put my function and config files in a web-space directory. However, I been thinking it would be less bother to make stuff more secure if the functions, et al, were above the root directory. I realize, some hosts still don't let the owner use the space above the document_root. So, I'll provide a means so the directory can be installed under it.

Also, since this is MySQL, you need to make sure you make it non case-sensitive by using ILIKE instead of LIKE in that
SELECT statement.
$sql = "SELECT DISTINCT name FROM restaurants WHERE name iLIKE '$index_letter%'
GROUP BY name DESC";

I hope not, because you have a parse error on your second line, mysqli_prepare()
