Create a php shell.
I think you're aiming way too high. You should focus on small projects whilst at such a level of competence. Perhaps create a thread like this in the future...

@jur13n I am just basically getting good with OOP style and Database driven applications, I am not good with security and stuff, I am trying to learn safe ways of doing that. Thank you for telling me about shells, I will try to read that and try to understand the logic of that and try coding it.
// Edit @jur13n I read that wiki document, shells are viruses, and why do you want to code me one? I don't want to code viruses. Thank you for the Security wiki, it was really informative.
Sigh.Quote:

It also learns you to use php functions you never used before..
Learning purpose..
@jur13n can you explain me the logic of how it works? And I'll code it up and PM you the source and you can check if it is correct or not, okay? :P
Could you provide some earlier code samples?
There is no logic to how it works.Quote:

You think of your OWN logic to create it.
If you use a framework/template or what so ever.
You just create your OWN logic based on a logic that has been pre-created.
But knowing your skills so far, I don't presume you use any framework/template at all..

Oh ps.
If you really want to create a good application.
Make me a PDO mysql CRUD REST API in php
There are 3things here;
- CRUD
- REST
- PDO MySQL
Rest is a way of processing a request and/or sending data.
http://en.wikipedia.org/wiki/Represe...state_transfer
PDO MySQL:
http://nl1.php.net/pdo_mysql
use prepared statements etc.
CRUD:
Create, Read, Update, Delete.
- Create = INSERT (mysql)
- Read = SELECT
- Update = UPDATE
- Delete = DELETE
based on mysql stuff
I would like to have a an api, that I can send a request with as example;
SELECT
$param1
FROM $param2
WHERE $param3
I would request A SELECT with 3 parameters.
Make it class based.
This would be a good practice.
@jur13n I tried coding a tpl system but failed, I am going to re-start it after my portfolio is done, and I want more explanation, I dont understand. Plus I code in MySQLi Prepared Statements. ;P
Well, stop using mysql now.Quote:

If you failed in RainTPL... Do you even know how to work in a MVC framework?
@jur13n no I don't know to work in MVC can you teach me? And I am using MySQLi prepared Statements no mysql, and sure, I will use PDO if you are suggesting me that. I'll google it and try learning it out. And I never uesd RainTPL, I tried to code my own.
How about creating error/exception handling system,
- which would allow to store application level error message(that can be easily integrated with template system)
- for example store custom errors into static variable then retrieve and format them when needed
- enable put limit to log file size
- if log size has exceeded max limit then take appropriate action
- overwrite
- create and write to new file
- ignore
- etc
- option to disable duplicated log writing
- only if log file size do not exceed max log size
- and only if exceed action is not ignore, since it would require open and search old log file(it would be slow on big logs)
- convert php internal errors to exceptions
- add debug options and strict mode
Okey, i got kinda interested making this myself, so here it is :D
