i finally got it to work but when i type SHOW DATABASES in the Type in SQL query as shown in the tutorial i get an error saying mysql_num_fields() expects parameter 1 to be resource, object given in C:\wamp64\www\mysql_send.php on line 39

this is the code and i wrote exactly as shown in the book can someone tell me where is problem?

/*Program: mysql_send.php
*Desc: PHP program that sends an SQL query to the
* MySQL server and displays the results.
echo "<html>
<head><title>SQL Query Sender</title></head>
if(ini_get("magic_quotes_gpc") == "1")
$_POST['query'] = stripslashes($_POST['query']);

/* Section that executes query and displays the results */
$cxn = mysqli_connect($host,$user,$password,
$result = mysqli_query($cxn,$_POST['query']);
echo "Database Selected: <b>{$_POST['database']}</b><br>
Query: <b>{$_POST['query']}</b>
if($result == false)
echo "<h4>Error: ".mysqli_error($cxn)."</h4>";
elseif(@mysqli_num_rows($result) == 0)
echo "<h4>Query completed.
No results returned.</h4>";
/* Display results */
echo "<table border='1'><thead><tr>";
for($i = 0;$i < mysql_num_fields($result);$i++)

echo "<th>".mysql_field_name ($result,$i) .
echo "</tr></thead>
for ($i=0;$i < mysqli_num_rows($result);$i++)
echo "<tr>";
$row = mysqli_fetch_row($result);
foreach($row as $value)
echo "<td>".$value."</td>";
echo "</tr>";
echo "</tbody></table>";
/* Display form with only buttons after results */
$query = str_replace("'","%&%",$_POST['query']);
echo "<hr><br>
<form action='{$_SERVER['PHP_SELF']}' method='POST'>
<input type='hidden' name='query' value='$query'>
<input type='hidden' name='database'
<input type='submit' name='queryButton'
value='New Query'>
<input type='submit' name='queryButton'
value='Edit Query'>

/* Displays form for query input */
if (@$_POST['queryButton'] != "Edit Query")
$query = " ";
