How can one extract only a specific part of a database entry in PHP?

To extract only a specific part of a database entry in PHP, you can use SQL queries with specific conditions to retrieve only the desired data. For example, you can use the SELECT statement with WHERE clause to filter the data based on certain criteria. Once you have fetched the data from the database, you can then extract the specific part you need from the result set. 

// Connect to the 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);
}

// SQL query to fetch specific part of database entry
$sql = "SELECT specific_column FROM table_name WHERE condition = 'desired_value'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Specific part of database entry: " . $row["specific_column"];
    }
} else {
    echo "0 results";
}

$conn->close();
