How can one access array columns in PHP regardless of their names?

When working with arrays in PHP, if you need to access array columns regardless of their names, you can loop through the array and access each column dynamically using a foreach loop. By iterating through the array, you can access each column without knowing its specific name, making your code more flexible and adaptable to different array structures. 

// Sample array with columns of unknown names
$array = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Jane', 'age' => 25],
    ['name' => 'Bob', 'age' => 40]
];

// Accessing array columns dynamically
foreach ($array as $row) {
    foreach ($row as $key => $value) {
        echo $key . ': ' . $value . '<br>';
    }
    echo '<br>';
}
