What other PHP functions or methods can be used to manipulate strings in a similar way to truncation?

To manipulate strings in PHP in a similar way to truncation, you can use functions like `substr`, `mb_substr`, or `str_replace`. These functions allow you to extract a portion of a string based on a starting position and length, or to replace a specific substring within a string with another value.

// Using substr to truncate a string
$string = "This is a long string that needs to be truncated";
$truncated_string = substr($string, 0, 20);
echo $truncated_string;

// Using str_replace to replace a substring
$string = "Hello, World!";
$new_string = str_replace("Hello", "Goodbye", $string);
echo $new_string;
