Is the "select distinct" function a suitable solution for this problem in PHP/MySQL?

Issue: The "select distinct" function in MySQL can be used to retrieve unique values from a database table. This can be useful when you want to eliminate duplicate entries and only display distinct values. Solution: To use the "select distinct" function in PHP/MySQL, you can simply write a SQL query that includes the "distinct" keyword before the column name you want to retrieve unique values for. Here is an example code snippet: 

<?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);
}

// SQL query to select distinct values from a table
$sql = "SELECT DISTINCT column_name FROM table_name";

$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Value: " . $row["column_name"] . "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
