What are the common reasons for discrepancies in data display between different PHP pages within the same application, and how can this be rectified?

Common reasons for discrepancies in data display between different PHP pages within the same application include using different database queries, inconsistent data processing logic, or caching issues. To rectify this, ensure that all pages are using the same database queries and data processing methods, and clear any cached data that may be causing inconsistencies. 

// Example code to ensure consistent data display between PHP pages

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Query to fetch data
$stmt = $pdo->query('SELECT * FROM mytable');

// Fetch data as an associative array
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Display data on the page
foreach ($data as $row) {
    echo $row['column1'] . ' - ' . $row['column2'] . '<br>';
}
