[PHP] Open a stream to the shell..
Hello, is it possible to open a stream in which I can write commands
and read output from them to a shell like bash? I want to do this
because this program can not be completed with just a `backtick` or
shell_exec() command, as it's somewhat user-interactive.
As an example, let's say I want to get cdecl to explain to me what
char *horse means. I would type:
# icdecl/i
Type `help' or `?' for help
cdecl iexplain char *horse/i
declare horse as pointer to char
cdecl iexit/i
...where input is surrounded by ithese/i. This would be difficult
or impossible to do with shell_exec, especially if halfway-through you
have to do some calculating before you can know what to ask cdecl
next.
So I want to know whether you can somehow open a stream to a shell,
and execute commands there. Like...
$fp = fopen('/bin/bash', 'rw');
$output = fgets($fp);
fputs($fp, 'cdecl');
$output = fgets($fp);
$output = fgets($fp);
fputs($fp, 'explain char *horse');
$expl = fgets($fp);
/* Right now you could do some calculations and figure out what to do next. */
$output = fgets($fp);
fputs($fp, 'exit');
$output = fgets($fp);
fclose($fp);
Now this obviously wouldn't work, as it would overwrite the bash
executable if you had proper access, but it's just to get the idea
across.
So, does anyone know how I can do this?

[PHP] PHP5 OOP
Hello, I'm trying to get the hang of OOP here but can't quite figure
out how to relate these classes. I've got one for the main project,
one for the database, and one for a user. Somehow I need to get the
user access to the database, without cumbersome constructor calls
involving a copy of the instance of the class itself.
// main project class
class gfusion {
protected static $db;
function __construct() {
$this-db = new db;
}
}
// database class
class db {
private $link;
private $query;
private $result;
...
function query($query);
function fetch_row();
function fetch_rows();
...
}
// user class
class user {
private $id;
private $group_id;
private $login;
private $password;
/* Somehow I need to get the db class instance here. */
function __construct($id = false) {
if (is_numeric($id)) {
print_r($this);
$this-db-query('SELECT * FROM user WHERE id = ' . $id);
$user_info = $this-db-get_row();
$this-id = $user_info['id'];
$this-group_id = $user_info['group_id'];
$this-login = $user_info['login'];
$this-password = $user_info['password'];
}
}
...
}
I tried extending the user class from the project class, but that
didn't work, because the $db var was empty. I tried changing it to
static, but it didn't inherit the $db variable for some reason. So,
how can I make this work, so I can write a bunch of classes that can
blindly use $this-db or something similar without having to worry
about setting it in the constructor? I thought about setting it as a
global, but that didn't seem very... OOP.

Re: [PHP] Re: How to escape apostrophe in HTML textbox exactly???
What's wrong with addslashes() on the way in and stripslashes() on the way out? Why would you want to convert it to it's HTML entity? -- Joel Kitching http://midgardmanga.keenspace.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: How to escape apostrophe in HTML textbox exactly???
1. addslashes() is not as robust as other solutions like
mysql_escape_string().
What exactly is the difference between the two?
2. in either case the slashes will be non-existant when the data is
actually inserted into the database.
for example:
$mystring = hello here is my string. it has an ' (apostrophe) in it.;
$sql =
INSERT INTO data
(thestring)
VALUES ('$mystring');
when then is parsed it will look like this:
INSERT INTO data
(thestring)
VALUES ('hello here is my string. is has an ' (apostrophe) in
it.')
as you can see the ' in the original string is going to cause a problem.
by escaping it with mysql_escape_string() (or another comparable
function) you'll get the following:
INSERT INTO data
(thestring)
VALUES ('hello here is my string. is has an \' (apostrophe) in
it.')
this string, although it now contains a slash that we originally did not
want, this slash not exist once the data is actually inserted into the
database. it's merely there to tell the database hey, please ignore the
' that comes directly after me.
s... when you pull the data *out* of the database the \ will not
exist and you therefore do not need to perform stripslashes().
I tried using addslashes() on the string in the query, and then
SELECTing it, and the slashes are included. Does
mysql_escape_string() not do this?
and now to the second part... why use htmlentities()? that is for
displaying data within a form element OR (i hope i have this right)
preventing XSS (Cross Site Scripting attacks).
hope this helps!
chris.

[PHP] OOP, Classes, Sharing Code
I'm kind of new to OOP, so bear with me here... I have a portfolio which contains albums. These albums contain photos. So it would be natural to declare the classes: Portfolio Album Photo It seems to me that none of these classes have the is a relationship, and therefore can not be extended from each other. The reason I wish to do this, is because listing albums and listing photos use almost exactly the same code. i.e. // The constructor would automatically fill in the album's variables from the database. $album = new Album($album_id); // This would print out the HTML for the list of photos. $album-list_photos(); ... or the same thing with Portfolio, which would list the albums. The only thing that's different is the links to which the anchors are pointing, and the content. (Thumbnails.) So my question is, should I just duplicate the code in each class (Portfolio and Album), or is there a better way of organizing all of this? -- Joel Kitching http://midgardmanga.keenspace.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Like using the variable $items for the array of classes of either albums or photos.

There are many examples (in the comments) at the manual entry for
