Is it necessary to use a loop when storing a single database cell in a variable in PHP?

When storing a single database cell in a variable in PHP, it is not necessary to use a loop. You can directly fetch the value from the database using a query and store it in a variable. This can be achieved by executing a SELECT query that fetches the specific cell value based on certain criteria, such as an ID. 

<?php
// 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);
}

// Select a specific cell value from the database
$sql = "SELECT cell_value FROM table_name WHERE id = 1";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Fetch the value and store it in a variable
    $row = $result->fetch_assoc();
    $cellValue = $row["cell_value"];
    
    // Output the value
    echo $cellValue;
} else {
    echo "0 results";
}

$conn->close();
?>
