What are some common reasons why only one forum in a category is being displayed when fetching data in PHP?

When only one forum in a category is being displayed when fetching data in PHP, it is likely due to an issue with the SQL query being used to retrieve the data. This could be caused by a filtering condition that limits the results to only one record, or by a mistake in the query logic that unintentionally restricts the output. To solve this issue, review the SQL query being used to fetch the data and ensure that it is correctly retrieving all the relevant records from the database. 

// Example SQL query to fetch forums in a specific category
$sql = "SELECT * FROM forums WHERE category_id = :category_id";

// Bind the category ID parameter
$statement = $pdo->prepare($sql);
$statement->bindParam(':category_id', $category_id, PDO::PARAM_INT);
$statement->execute();

// Fetch all forums in the category
$forums = $statement->fetchAll(PDO::FETCH_ASSOC);

// Check if any forums were retrieved
if (count($forums) > 0) {
    // Display the forums
    foreach ($forums as $forum) {
        echo $forum['forum_name'] . "<br>";
    }
} else {
    echo "No forums found in this category.";
}
