Hi trying to following program
<?php
//define class database connectivity
class dbconnect
{
    var $conn;
  function dbcon()
    {
    if(!isset($conn))           //database connectivity
        {
        $conn = mysqli_connect('localhost','root','username','password');
        }
        if($conn==false)
        {
        return mysqli_connect_error();   // return error message if connection fails
        }
        return $conn;           // return connectivity 
    }
    }
//define class sql injection
class injection extends dbconnect
{
    function inject($char)

        $data=new dbconnect;

        $char = stripcslashes($char);               // inject slashes 
        $char = htmlspecialchars($char);                // inject special characters
        $char = mysqli_real_escape_string($dataobj,$char);  // mysql injection variable,databaseobject variable
        return $char;                           // return safe data
    }
