Deprecated: mysql_connect(): The mysql extension is deprecated in php

i am getting warning at my php website suddenly .
i am getting error with mysql_connect . it working previously.
Error or warning

Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in  

so i do some effort . i checked with web-hosting people they said they upgrade php and want to solve it and so i did not get any problem.

so how can i remove deprecated mysql_connect function and use mysqli and PDO instead.

you should use mysql class and PDO also instead

1. Mysql class

$conn= new mysqli('your-server-name','database-name','database-password','database-name');// not needed mysql_select_db function 
 $query= "select * form tablename";
if ($result = $mysqli->query($query)) {
    while ($row = $result->fetch_row()) {
        printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
    /* free result set */

you can prepare statement before run it .

$query = "INSERT INTO tablename(`field-1`,`field-2`) VALUES (?,?)";
$stmt = $mysqli->prepare($query);
// now you can replace blank value in query with as many time as you want with bind 
$stmt = $stmt ->bind_param("ss","value-1",'value-2');
//first argument stand for value type here s for string value
/* execute prepared statement */

yes Mysql extension deprecated soon in php 7 , should be replaced with Mysqli

so mysql_connect should be replace with mysqli_connect

//instead of  $conn=mysql_connect('yourserver','database-name','database-password');
mysqli_select_db($conn,"database-name");// need to pass the connection reference as first argument
//instead of mysql_select_db("database-name");
mysqli_query($conn,"select * from tablename");
//instead of msyql_query("select * from tablename");

so in short use mysqli instead of mysql and pass the connection as first argument in the function .
but this function also removed in future version so avoid to use it also
