In this post i would like to explain about how to implementing object oriented programming in php, How to create class, and how to call the method of that class.
Class code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 | <?php /********************************************************************** * Author : Anil Kumar Panigrahi * E-mail : [email protected] * Created on: 6th June 2011 * Version : 1.0 * Project : Database Interactions * Page : User Class * Company : Anil Labs (http://www.anillabs.com) * Modified on : * Modified by : *************************************************************************/ class Users{ /***************************************************************** Users is a constructor to establish the database connection *****************************************************************/ private $dbHost; private $dbUser; private $dbPassword; private $dbName; private $first_name; private $last_name; private $user_name; private $password; private $id; private $con; public function __construct($dbHost,$dbUser,$dbPassword,$dbName){ $this->dbHost = "{DATABASE SEVER}"; $this->dbUser = "{USERNAME}"; $this->dbPassword="{PASSWORD}"; $this->dbName= "{DBNAME}"; $mysqli = new mysqli($this->dbHost,$this->dbUser,$this->dbPassword,$this->dbName); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } } /***************************************************************** insert function to insert data into database *****************************************************************/ public function insert ($first_name,$last_name,$user_name,$password){ $stmt1 = $mysqli->prepare("INSERT INTO USERS VALUES (?, ?,?,?)"); $stmt1->bind_param('ssss', $this->first_name,$this->last_name,$this->user_name,$this->password); $this->first_name=$first_name; $this->last_name=$last_name; $this->user_name=$user_name; $this->password=$password; $stmt1->execute(); $stmt1->close(); $id = $mysqli->insert_id; return $id } /***************************************************************** udpate function to update data into database *****************************************************************/ public function update($id,$first_name,$last_name,$user_name,$password){ $stmt1 = $mysqli->prepare("UPDATE INTO USERS first_name=?,last_name=?,user_name=?,password=? where user_id=?"); $stmt1->bind_param('ssssi', $this->first_name,$this->last_name,$this->user_name,$this->password,$this->id); $this->first_name = $first_name; $this->last_name= $last_name; $this->user_name= $user_name; $this->password= $password; $this->id= $id; $result=$stmt1->execute(); $stmt1->close(); if($result) return true; else return false; } /***************************************************************** delete function to dalete data from database *****************************************************************/ public function delete($id){ $stmt1 = $mysqli->prepare("DELETE FROM USERS WHERE user_id =?"); $stmt1->bind_param('i', $this->id); $this->id= $id; $result=$stmt1->execute(); $stmt1->close(); if($result) return true; else return false; } /***************************************************************** retrieve function to get data from database *****************************************************************/ public function retrieve($id){ $stmt1 = $mysqli->prepare("SELECT * FROM USERS WHERE user_id =?"); $stmt1->bind_param('i', $this->id); $this->id= $id; $result=$stmt1->execute(); $stmt->bind_result($first_name, $last_name,$user_name,$password); while ($stmt->fetch()) { printf ("%s ,%s,%s,%s\n", $first_name, $last_name,$user_name,$password); } $stmt1->close(); } public __destruct() { unset($this->dbHost); unset($this->dbUser); unset($this->dbPassword); unset($this->dbName); unset($this->first_name); unset($this->last_name); unset($this->user_name); unset($this->password); unset($this->id); $mysqli->close(); unset($this->con); } } ?> |
It is useful for who is newbie of php classes. This post not useful for advanced programmer.
