How can basic array manipulation be used to extract specific data from a fetched array in PHP?

When working with fetched arrays in PHP, basic array manipulation can be used to extract specific data by accessing the array elements using their keys or indexes. This can be done by using functions like `array_column()` to extract specific columns from a multidimensional array or using loops like `foreach` to iterate through the array and extract the desired data. 

// Example code to extract specific data from a fetched array in PHP

// Assuming $fetchedArray is the fetched array containing data
$fetchedArray = [
    ['id' => 1, 'name' => 'John', 'age' => 25],
    ['id' => 2, 'name' => 'Jane', 'age' => 30],
    ['id' => 3, 'name' => 'Alice', 'age' => 28]
];

// Extracting names from the fetched array
$names = array_column($fetchedArray, 'name');
print_r($names);

// Extracting names and ages from the fetched array
foreach ($fetchedArray as $data) {
    echo $data['name'] . ' is ' . $data['age'] . ' years old.<br>';
}
