Are there any specific PHP functions or libraries that can simplify the process of displaying SQL strings in tabular form in a PHP application?

To simplify the process of displaying SQL strings in tabular form in a PHP application, you can use the PDO extension in PHP along with the fetchAll() method to retrieve data from a database query and then display it in a tabular format using HTML.

<?php
// Connect to the database
$dsn = 'mysql:host=localhost;dbname=database_name';
$username = 'username';
$password = 'password';
$dbh = new PDO($dsn, $username, $password);

// Prepare and execute the SQL query
$stmt = $dbh->prepare('SELECT * FROM table_name');
$stmt->execute();

// Fetch all results into an associative array
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Display results in a tabular format
echo '<table>';
echo '<tr>';
foreach ($results[0] as $key => $value) {
    echo '<th>' . $key . '</th>';
}
echo '</tr>';
foreach ($results as $row) {
    echo '<tr>';
    foreach ($row as $value) {
        echo '<td>' . $value . '</td>';
    }
    echo '</tr>';
}
echo '</table>';
?>
