How can I generate a array from database?

I have a table in a database, column call l_parameter where I have information that should go into a array.
How do I add all rows that the table contains into a array.

array example:
$language_codes = array('en','sv','fi');

// Connect to database
$dbhost = "localhost";
$dbuser = "username";
$dbpass = "password";
$dbname = "databasename";
$db = mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($dbname,$db);

/*
select all rows from the language table and place
the table attribute lang_abbreviation into array $langAbbreviation
*/

$sql1 = "SELECT * from language ";
$result1 = mysql_query($sql1, $db);
$langCount = mysql_num_rows($result1);
for ($i=0; $i < $langCount; $i++) {
    $row = mysql_fetch_array($result1);
    $langAbbreviation[$i] = $row["lang_abbreviation"];
}

// show the array on your page
for ($i=0; $i < $langCount; $i++) {
    echo $langAbbreviation[$i] ;
}
