What are some common array functions in PHP that can be utilized for rearranging characters in an array?

To rearrange characters in an array in PHP, you can use functions like `str_split()` to split a string into an array of characters, `shuffle()` to randomize the order of elements in an array, and `implode()` to concatenate the array elements back into a string. 

$string = "hello";
$characters = str_split($string); // Split the string into an array of characters
shuffle($characters); // Shuffle the order of characters in the array
$newString = implode($characters); // Concatenate the array elements back into a string
echo $newString; // Output the rearranged string
