Step 1 : Database Configuration


In first step, You have to add your database configuration in database.php file So let's create database.php file put the bellow code.

database.php

<?php

class database{

public $que;

private $servername='localhost';

private $username='root';

private $password='root';

private $dbname='oop_test';

private $result=array();

private $mysqli='';

public function __construct(){

$this->mysqli = new mysqli($this->servername,$this->username,$this->password,$this->dbname);

}

public function insert($table,$para=array()){

$table_columns = implode(',', array_keys($para));

$table_value = implode("','", $para);

$sql="INSERT INTO $table($table_columns) VALUES('$table_value')";

$result = $this->mysqli->query($sql);

}

public function update($table,$para=array(),$id){

$args = array();

foreach ($para as $key => $value) {

$args[] = "$key = '$value'";

}

$sql="UPDATE $table SET " . implode(',', $args);

$sql .=" WHERE $id";

$result = $this->mysqli->query($sql);

}

public function delete($table,$id){

$sql="DELETE FROM $table";

$sql .=" WHERE $id ";

$sql;

$result = $this->mysqli->query($sql);

}

public $sql;

public function select($table,$rows="*",$where = null){

if ($where != null) {

$sql="SELECT $rows FROM $table WHERE $where";

}else{

$sql="SELECT $rows FROM $table";

}

$this->sql = $result = $this->mysqli->query($sql);

}

public function __destruct(){

$this->mysqli->close();

}

}

?>
