In a PHP project with language translations stored in a database, is it better to retrieve all translations at once or make individual queries for each text needed?

When working with language translations stored in a database in a PHP project, it is generally better to retrieve all translations at once rather than making individual queries for each text needed. This approach reduces the number of database queries, improving performance and efficiency. You can store all translations in an associative array and then access the required texts as needed.

// Retrieve all translations from the database
$query = "SELECT language_key, translation FROM translations";
$result = mysqli_query($connection, $query);

$translations = [];
while ($row = mysqli_fetch_assoc($result)) {
    $translations[$row['language_key']] = $row['translation'];
}

// Access the required text using the translations array
echo $translations['hello']; // Output: Hello
echo $translations['goodbye']; // Output: Goodbye
