POST变量，其中包含数组

Question

As the title says

$champion = array();
for($i=1;$i<=$champ_number; $i++){
                    $champion[$i] = $_POST['champno'.$i];
}
echo '<input type="hidden" name="champion[]" value="'.$champion.'">';

What's the simplest least secure way to POST this variable $champion through POST is?

Answer 1

try to follow this simple format:

E.g. : FORM

 <form method="post" action="submit.php">  
    <?php 
    $champion=array('hiii','helloooo');

    echo '<input type="hidden" name="champion" value="'.htmlspecialchars(json_encode($champion)).'">';


    ?>
    <input type="submit" value="sub">
    </form>

your submit.php :

<?php 
$champions = json_decode($_POST['champion'], true);
echo $champions[1];// out put helloooo
?>
