i have written a small code to store the checkbox values into the db.
But its showing me a parse error . Unable to figure out what it could be .

<?php

$dbc = mysqli_connect('localhost', 'root', '', 'test')
    or die('Error connecting to MySQL server.');

if(isset($_POST['language']))
{
   $language = $_POST['language'];
   $n        = count($language);
   $i        = 0;

   

echo "$n";

 echo "The languages you selected are \r\n" .
        "<ul>";
   while ($i < $n)
   {
      echo "<li>{$language[$i]}</li> \r\n";
      $i++;
   }

  $query = "INSERT INTO check (ai,rdbms,os,cd,co) VALUES //  err     ('$language[$i -1]', '$language[$i - 1]', '$language[$i - 1]',  //  err   '$language[$i - 1]', '$language[$i - 1]' ) ";                          // err


   echo "</ul>";


$result = mysqli_query($dbc, $query)
    or die('Error querying database.');

  mysqli_close($dbc);

}
?>

the error its showing is

Parse error: parse error, expecting `']'' in C:\wamp\www\College Web Project\Check Box (tested).php on line 39

the html code is

<form method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">
Select the area of expertise ur good at <br>
<input name="language[]" type="checkbox" value="Artificial Intelligence">
Artificial Intelligence<br>
<input name="language[]" type="checkbox" value="DataBase">
DataBase <br>
<input name="language[]" type="checkbox" value="OperatingSystems">
OperatingSystems <br>
<input name="language[]" type="checkbox" value="CompilerDesigns">
CompilerDesigns<br>
<input name="language[]" type="checkbox" value="Computer Organization">
Computer Organization<br>
<input name="send" type="submit" id="send" value="Send!">
</form>

Ps : i have incorporated the html code in the same file as the php.

Seems fine except for the query you are building for your INSERT.
Maybe this will offer some assistance.
