What are some best practices for dynamically displaying table columns in PHP using array_column() and array_filter()?

When dynamically displaying table columns in PHP, you may want to filter the columns based on certain criteria before displaying them. One way to achieve this is by using array_column() to extract specific columns from a multidimensional array and array_filter() to apply a filter condition. This allows you to display only the columns that meet the specified criteria. 

// Sample multidimensional array representing table data
$tableData = [
    ['id' => 1, 'name' => 'John', 'age' => 25],
    ['id' => 2, 'name' => 'Jane', 'age' => 30],
    ['id' => 3, 'name' => 'Alice', 'age' => 28],
];

// Define columns to display based on a filter condition (e.g., display columns where age is greater than 25)
$filteredColumns = array_filter(array_column($tableData, 'age'), function($value) {
    return $value > 25;
});

// Loop through the filtered columns and display them
foreach ($filteredColumns as $column) {
    echo $column . "<br>";
}
