Example: Deleting guests using mySQLi Procedural

Record deleted successfully

Here is the code for deleting the record from the database table.

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

// 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 MyGuests WHERE id=5";

if ($conn->query($sql) === TRUE) {
  echo "Record deleted successfully";
} else {
  echo "Error deleting record: " . $conn->error;
}

$conn->close();
?>

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

Here is the code for accessing the database and display the information in a table.

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

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

$sql = "SELECT id, firstname, lastname, email FROM MyGuests";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
  echo "<table><tr><th>ID</th><th>Name</th><th>Email</th><Registration Date</th></tr>";
  // output data of each row
  while($row = $result->fetch_assoc()) {
    echo "<tr style='background-color:yellow';>
<td>".$row["id"]."</td><td>".$row["firstname"]." ".$row["lastname"]."</td>".$row["email"]."</td><td>".$row["reg_date"]."</td></tr>";
  }
  echo "</table>";
} else {
  echo "<p>0 results</p>";
}
$conn->close();
?>
