Some of them are: substringBetween, splice, startWith, endsWith and squeeze. It is also possible to use PHP internal functions, or custom functions, to manipulate the string.

示例代码:

include('string.php');

$str = new String('sometext');
echo $str->length; //prints 8

?>

我以前从未使用过此类，但是通过查看其文档，它具有一些非常有趣的方法.大写，charAt，compareTo，contains等.

I have never used this class before but by looking at its documentation it has some pretty interesting methods. capitalize, charAt, compareTo, contains, etc..
