Hi all
I would like to challenge a PHP guru to make a decent tutorial on OOP. I have read a ton of tuts on OOP on the net , but for some odd reason the principles described, never seem to work.
I know what OOP programming is all about, I learnded about OOP principels in Pascal 7.0. But never learned to use it in real life. So if someone with real life OOP knowlege is willing to write a tut that is newbee freindly, I will gladly reveiw the tut and ask the "right" questions to the material, until we have a fantastic tut. Maybe we can have the tut as a sticky.
I suggest that we use PHP5 for the tut. I have a book with a sql class, only the book says nothing about how to use it. We could use that class as a starting example, here is the class:
Class mysql{
private $linkID;
private $host;
private $user;
private $pswd;
private $db;
/Class constructor, initializes host etc/
function __construct($host,$user,$pswd, $db){
$this->host = $host;
$this->user = $user;
$this->pswd = $pswd;
$this->db = $db;
}
/connect to mySQL db/
function connect(){
try{
$this->linkID = @mysql_connect($this->host,$this->user,$this->pswd);
if (! $this->linkID)
throw new Exception("Could not connect to mySQL database!");
}
catch (Exception $e){
die($e->getMessage());
}
}
lets have a form from another PHP page contact the class and log in to the database. Like so:
<?php
include "mysql.class.php";
//create new mysql object
$mysqldb = new mysql("host","user","pswd","db");
//connect to database
$mysqldb->connect();
?>
Personally, I have tried the above a dusin times and it has never worked. I hope somebody takes up the challenge.
