How can specific data be retrieved from a MySQL table based on an ID or other information in PHP?

To retrieve specific data from a MySQL table based on an ID or other information in PHP, you can use a SQL query with a WHERE clause to filter the results. The WHERE clause allows you to specify a condition that must be met for the data to be included in the result set. By passing the ID or other information as a parameter in the query, you can retrieve the specific data you need. 

<?php
// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Retrieve data based on ID
$id = 1; // ID of the data to retrieve
$sql = "SELECT * FROM table_name WHERE id = $id";
$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["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
