<?php
////////class defination////////////
class dbhandler
{
//include "dbcon.php";
public function connectdb()
{
//$connection=mysql_connect($dbhost,$dbuser,$dbpass) or print "not connected";

mysql_close($connection);
}
////////////function for adding the record to db ////////////

$results=mysql_query($qry) or
die(mysql_error());
return $results;
}
////////////function for deleting the record from db ////////////
public function deleterecord($qry)

$results=mysql_query($qry) or
die(mysql_error());
return true;
}
/////////////function for updating record//////////////
public function updaterecord($qry)
{
$results=mysql_query($qry) or
die(mysql_error());
return true;
}

}
?>

 

Put it in the function connectdb() like this.

public function connectdb()
{
include "dbcon.php";

PHP:

 

vbot, i think it is be more simple

include "dbcon.php";

class dbhandler
{ //define data as global variable
global $dbhost;
global $dbuser;
......

public function connectdb()
{


and this variables will be can using along all script

 

ps/ your class bad for using.

use simple function

function q ($string) {
return mysql_query($string) or $debugger .= (mysql_error());
}

for debugging not using 'die'

 

It's better to use the define() function to define the details as globals. Once you do that you can just put:

require_once("dbcon.php");

Code (markup):

At the top of the code and then call the globals from within the class.

 

of course, its best solution)

 

Actually, if you want to deal with classes, use __construct() ! Also, instead of using simple variables ( database information ), use define()

function __construct() {
     require_once('dbcon.php');
     // assign your config file values to class variables, etc.
}
