Data can be deleted from MySQL tables by executing SQL DELETE statement through PHP function mysqli_query.
Below is a simple example to delete records into MyGuests table. To delete a record in any table it is required to locate that record by using a conditional clause. Below example uses primary key to match a record in MyGuests table.
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
// sql to delete a record
$sql = "DELETE FROM MyGuests WHERE id=3";
if (mysqli_query($conn, $sql)) {
echo "Record deleted successfully";
} else {
echo "Error deleting record: " . mysqli_error($conn);
}
mysqli_close($conn);
?>
