How can the SQL query be modified to only retrieve entries with a link_guthaben greater than 0 in the PHP code snippet?

To modify the SQL query to only retrieve entries with a link_guthaben greater than 0, you can add a WHERE clause to filter the results. In the WHERE clause, specify the condition "link_guthaben > 0" to only select entries where the link_guthaben column has a value greater than 0. Here is the modified PHP code snippet with the updated SQL query: 

<?php
// Establish a connection to the database
$pdo = new PDO("mysql:host=localhost;dbname=your_database", "username", "password");

// Prepare the SQL query with a WHERE clause to filter entries with link_guthaben greater than 0
$sql = "SELECT * FROM your_table WHERE link_guthaben > 0";
$stmt = $pdo->prepare($sql);

// Execute the query
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Output the results
foreach ($results as $row) {
    echo "ID: " . $row['id'] . ", Link Guthaben: " . $row['link_guthaben'] . "<br>";
}
?>
