What are some common methods for manipulating array values in PHP, particularly for reversing the order of partial values?

To reverse the order of partial values in an array in PHP, you can use the array_slice() function to extract the portion of the array that you want to reverse, then use the array_reverse() function to reverse the order of those values, and finally use array_splice() to replace the original portion with the reversed values.

// Original array
$array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

// Reverse the order of values from index 2 to 6
$partialValues = array_slice($array, 2, 5);
$reversedPartialValues = array_reverse($partialValues);
array_splice($array, 2, 5, $reversedPartialValues);

// Output the modified array
print_r($array);
