Having trouble with the php connection? Try this code for free.  Below a simle example to insert a record into staff table.

Example:

Try out following example to insert record into staff table.
<?php
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
  die('Could not connect: ' . mysql_error());
}
$sql = 'INSERT INTO employee '.
       '(name, address, salary, date) '.
       

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);
?>
In real application, all the values will be taken using HTML form and then those values will be captured using PHP script and finally they will be inserted into MySQL tables.
While doing data insert its best practice to use function get_magic_quotes_gpc() to check if current configuration for magic quote is set or not. If this function returns false then use function addslashes() to add slashes before quotes.

Example:

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

if(! get_magic_quotes_gpc() )
{
   $name = addslashes ($_POST['name']);
   $address = addslashes ($_POST['address']);
}
else
{
   $name = $_POST['name'];
   $address = $_POST['address'];
}
$salary = $_POST['salary'];

$sql = "INSERT INTO employee ".
       "(name, address, salary, date) ".
       "VALUES('$name','$address','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>
