What is the difference between sort() and array_multisort() functions in PHP?

The main difference between sort() and array_multisort() functions in PHP is that sort() is used to sort an array in ascending order, while array_multisort() is used to sort multiple or multidimensional arrays based on one or more key values. If you have a multidimensional array that needs to be sorted based on specific keys, you should use array_multisort(). 

// Example of using array_multisort() to sort a multidimensional array based on a specific key
$data = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 35]
];

// Sort the array by 'age' key in ascending order
array_multisort(array_column($data, 'age'), SORT_ASC, $data);

// Output the sorted array
print_r($data);
