When working with PHP arrays, what are the advantages and disadvantages of using array functions like array_sum, count, and array_column for data analysis tasks?

When working with PHP arrays for data analysis tasks, using array functions like array_sum, count, and array_column can provide a quick and efficient way to perform calculations and extract specific data from arrays. These functions can help simplify complex data analysis tasks and make the code more readable. However, it's important to be aware of the limitations of these functions, such as potential performance issues with large arrays or the need for additional error handling when working with multidimensional arrays.

// Example of using array functions for data analysis tasks
$data = [10, 20, 30, 40, 50];

// Calculate the sum of the array
$sum = array_sum($data);
echo "Sum: " . $sum . PHP_EOL;

// Get the number of elements in the array
$count = count($data);
echo "Count: " . $count . PHP_EOL;

// Extract a specific column from a multidimensional array
$users = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Jane', 'age' => 25],
    ['name' => 'Alice', 'age' => 35]
];

$names = array_column($users, 'name');
print_r($names);
