PHP Delete Data From MySQL

The DELETE statement is used to delete records from a table:

DELETE FROM table_name
WHERE some_column = some_value

look at the "Student" table:

ID                    name                    lastname                    admsn_date
1                    Ankit                    Bhardwaj                    6/9/2016
2                    Ashish                   Rajput                       5/9/2016
3                    Rahul                     Paswan                     4/9/2016

The following examples delete the record with id=2 in the "Student" table:

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "data";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

// sql to delete a record
$sql = "DELETE FROM Student WHERE id=2";

if ($conn->query($sql) === TRUE) {
    echo "Record deleted successfully";
} else {
    echo "Record Can't Delete: " . $conn->error;
}

$conn->close();
?>

After the record is deleted, the table will look like this:

ID                    name                    lastname                    admsn_date
1                    Ankit                    Bhardwaj                    6/9/2016
2                    Rahul                    Paswan                      4/9/2016
