What are some best practices for dynamically reacting to varying numbers of columns in PHP?

When dynamically reacting to varying numbers of columns in PHP, one best practice is to use a loop to iterate through the columns and perform actions accordingly. Another approach is to use an associative array to store column names and values, allowing for flexible handling of different column configurations. Additionally, consider using conditional statements to check for the presence of specific columns before attempting to process them. 

// Example code snippet for dynamically reacting to varying numbers of columns in PHP

// Assuming $columns is an array containing column names
// and $data is an associative array with column names as keys and values as values

foreach ($columns as $column) {
    if (array_key_exists($column, $data)) {
        // Process the column value here
        echo "Column $column: " . $data[$column] . "<br>";
    } else {
        // Handle missing columns if necessary
        echo "Column $column not found!<br>";
    }
}
