Is there a way to set default values in a while loop or select statement in PHP, similar to setting default values in a function?

In PHP, you can set default values for variables within a while loop or select statement by using the ternary operator. This allows you to assign a default value if the variable is not set or empty. By using this approach, you can ensure that your variables have a default value even if they are not explicitly defined within the loop or select statement. 

// Example of setting default values in a while loop
$counter = 0;
while ($counter < 5) {
    $value = isset($array[$counter]) ? $array[$counter] : 'default_value';
    // Use $value in your code
    $counter++;
}

// Example of setting default values in a select statement
$query = "SELECT column_name FROM table_name";
$result = mysqli_query($connection, $query);
while ($row = mysqli_fetch_assoc($result)) {
    $value = isset($row['column_name']) ? $row['column_name'] : 'default_value';
    // Use $value in your code
}
