Select Data From a MySQL Database

The SELECT statement is used to select data from one or more tables:

or we can use the * character to select ALL columns from a table:

<?php
$servername = “localhost”;
$username = “username”;
$password = “password”;
$dbname = “myDB”;

// 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 FROM MyGuests”;
$result = $conn->query($sql);

if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo “id: ” . $row[“id”]. ” – Name: ” . $row[“firstname”]. ” ” . $row[“lastname”]. “<br>”;
}
} else {
echo “0 results”;
}
$conn->close();
?>
