I have a html form which has a select list box from which you can select multiple values because its multiple property is set to multiple. Consider form method is \'GET\'. T

    This will display the selected values:

    <?php

    if ($_POST) { 
        foreach($_POST['select2'] as $selected) {
            echo $selected."<br>";
        }
    }

?>

    Use the following program for select the multiple values from select box.

    multi.php

    <?php
print <<<_HTML_
<html>
        <body>
                <form method="post" action="value.php">
                        <select name="flower[ ]" multiple>
                                <option value="flower">FLOWER</option>
                                <option value="rose">ROSE</option>
                                <option value="lilly">LILLY</option>
                                <option value="jasmine">JASMINE</option>
                                <option value="lotus">LOTUS</option>
                                <option value="tulips">TULIPS</option>
                        </select>
                        <input type="submit" name="submit" value=Submit>

    If you want PHP to treat $_GET['select2'] as an array of options just add square brackets to the name of the select element like this: <select name="select2[]" multiple …

    Then you can acces the array in your PHP script

    <?php
header("Content-Type: text/plain");

foreach ($_GET['select2'] as $selectedOption)
    echo $selectedOption."\n";

    $_GET may be substituted by $_POST depending on the <form method="…" value.

    Change:

    <select name="select2" ...

    To:

    <select name="select2[]" ...
