Splitting MySQL Results Into Two Columns Using PHP

Sometimes, the MySQL output result is too large to display in a single column on a web page and that's why, the best solution is to divide the data into two columns. In this article, we provide a simple solution to split the MySQL result sets into two columns using PHP.

Divide Large Data Into Two Columns Using PHP

Suppose, we have Indian states record, you can create a states table and copy paste this code in database or use your existing records.


INSERT INTO `states` (`id`, `state`) VALUES
(1, 'Andaman and Nicobar Islands'),(2, 'Andhra Pradesh'),(3, 'Arunachal Pradesh'),(4, 'Assam'),
(5, 'Bihar'),(6, 'Chandigarh'),(7, 'Chhattisgarh'),(8, 'Dadra and Nagar Haveli'),
(9, 'Daman and Diu'),(10, 'Delhi'),(11, 'Goa'),
(12, 'Gujarat'),(13, 'Haryana'),(14, 'Himachal Pradesh'),
(15, 'Jammu and Kashmir'),(16, 'Jharkhand'),(17, 'Karnataka'),
(18, 'Kerala'),(19, 'Lakshadweep'),(20, 'Madhya Pradesh'),
(21, 'Maharashtra (Mumbai)'),(22, 'Manipur'),(23, 'Meghalaya'),
(24, 'Mizoram'),(25, 'Nagaland'),(26, 'Orissa'),(27, 'Pondicherry'),
(28, 'Punjab'),(29, 'Rajasthan'),(30, 'Sikkim'),(31, 'Tamil Nadu'),
(32, 'Tripura'),(33, 'Telangana'),(34, 'Uttaranchal'),(35, 'Uttar Pradesh'),(36, 'West Bengal');

Now, let's create a PHP file name 'state.php' and copy paste the below code. Please make sure to replace the 'host', 'username', 'password' and 'databasename' with yours.

<html>
    <head>
        <title>Simplest way to divide data in two columns using PHP</title>
        <style type="text/css">
            table{ border: 2px solid deepskyblue; width: 30%; }
            tr{ width: 15%; }
            table tr:nth-child(odd){ background-color: lightskyblue;}
            table tr:nth-child(even){ background-color: lightgray;}
        </style>
    </head>
    <body>
    <?php 
        $conn = mysqli_connect('hostname', 'username', 'password', 'databasename');// connect to your host
        //Check for connection error
        if(mysqli_connect_error()){
         die("Error in DB connection: ".mysqli_connect_errno()." - ".mysqli_connect_error());
        }
        $select = "SELECT * FROM `states` ";
        $result = mysqli_query($conn, $select);// Select query to fetch data
        if(mysqli_num_rows($result)){
        echo "<table width='70%' >";
        $i = 0;
        while($row = mysqli_fetch_object($result)){
            $states = $rows->state;
            if($i % 2 == 0){
                echo '<tr>';
            }
            echo '<td>'.$states.'</td>';
            if($i % 2 == 1){
                echo '</tr>';
            }
            $i++;
        }
        echo "</table>";
         }
    ?>  
    </body>
</html>
