What are the differences between ksort, asort, and sort functions in PHP when sorting arrays?

The main difference between ksort, asort, and sort functions in PHP is the way they sort arrays. ksort sorts an array by keys in ascending order, asort sorts an array by values in ascending order while maintaining key-value associations, and sort sorts an array by values in ascending order while re-indexing the array numerically. 

// Example of using ksort
$fruits = array("d" => "lemon", "a" => "orange", "b" => "banana", "c" => "apple");
ksort($fruits);
print_r($fruits);

// Example of using asort
$fruits = array("d" => "lemon", "a" => "orange", "b" => "banana", "c" => "apple");
asort($fruits);
print_r($fruits);

// Example of using sort
$fruits = array("lemon", "orange", "banana", "apple");
sort($fruits);
print_r($fruits);
