Delete Data From a MySQL Table in PHP
The DELETE statement is used to delete
records from a table:
DELETE FROM table_name WHERE some_column = some_value
Notice:- The WHERE clause specifies which record or records that should be
deleted. If omit the WHERE clause, all records will be deleted!
"MyGuests" table:
id |
firstname |
lastname |
email |
reg_date |
1 |
John |
Doe |
john@example.com |

Examples:- Delete the record with id=3 in the "MyGuests" table:
Example (MySQLi Procedural)
<?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);
?>
Output:-
id |
firstname |
lastname |
