PHP How to Insert Data into MySQL Database
Data can be entered into MySQL tables by executing SQL INSERT statement through PHP function mysql_query. Below a simle example to insert a record into employee table.
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 following example to insert record into employee table.<?php
$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
die('Could not connect: ' . mysql_error());
}
$sql = 'INSERT INTO employee '.
'(emp_name,emp_address, emp_salary, join_date) '.
'VALUES ( "guest", "XYZ", 2000, 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);
?>

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>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
{
