This example show you to fetch random data from database table. In this example we create select statement with ORDER BY RAND() clause in PHP. The RAND( ) clause is used to fetch data from table randomly.


<?php

  $con = mysql_connect("localhost","root","root");

  if (!$con){

    die('Could not connect: ' . mysql_error());

  }

  mysql_select_db("test", $con);



  $result = mysql_query("SELECT email FROM users ORDER BY RAND()");



  if (!$result) {

    echo 'Could not run query: ' . mysql_error();

    exit;

  }



  $row = mysql_fetch_array($result);

  echo "<b>Email: </b>";

  echo $row['email']."<br>";

?>
