Try out this example by putting this code into add_employee.php, this will take input using HTML Form and then it will create records into database.

<html>
<head>
<title>Add New Record in MySQL Database</title>
</head>
<body>
<?php
if(isset($_POST['add']))
{
$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
  die('Could not connect: ' . mysql_error());
}

if(! get_magic_quotes_gpc() )
{
   $emp_name = addslashes ($_POST['emp_name']);
   $emp_address = addslashes ($_POST['emp_address']);
}
else
{
   $emp_name = $_POST['emp_name'];
   $emp_address = $_POST['emp_address'];
}
$emp_salary = $_POST['emp_salary'];

$sql = "INSERT INTO employee ".
       "(emp_name,emp_address, emp_salary, join_date) ".
       "VALUES('$emp_name','$emp_address',$emp_salary, NOW())";
mysql_select_db('test_db');
$retval = mysql_query( $sql, $conn );
if(! $retval )
{
  die('Could not enter data: ' . mysql_error());
}
echo "Entered data successfully\n";
mysql_close($conn);
}
else
{
?>
<form method="post" action="<?php $_PHP_SELF ?>">
<table width="400" border="0" cellspacing="1" cellpadding="2">
<tr>
<td width="100">Employee Name</td>
<td><input name="emp_name" type="text" id="emp_name"></td>
</tr>
<tr>
<td width="100">Employee Address</td>
<td><input name="emp_address" type="text" id="emp_address"></td>
</tr>
<tr>
<td width="100">Employee Salary</td>
<td><input name="emp_salary" type="text" id="emp_salary"></td>
</tr>
<tr>
<td width="100"> </td>
<td> </td>
</tr>
<tr>
<td width="100"> </td>
<td>
<input name="add" type="submit" id="add" value="Add Employee">
</td>
</tr>
</table>
</form>
<?php
}
?>
</body>
