SplArray

用途

用于处理字符串。

核心对象方法

核心类：EasySwoole\Spl\SplString。

setString

设置字符串。

string $string 数据项索引

function setString( string $string ) : SplString

<?php
/**
 * Created by PhpStorm.
 * User: root
 * Date: 19-1-9
 * Time: 上午10:10
 */
require './vendor/autoload.php';
$string = new \EasySwoole\Spl\SplString();
var_dump($string->setString('Hello, EasySwoole')->__toString());
/**
 * 输出结果过：
 * string(17) "Hello, EasySwoole"
 */

split

设置数组中某项的值。

int $length 每一段的长度

function split( int $length = 1 ) : SplArray

<?php
/**
 * Created by PhpStorm.
 * User: root
 * Date: 19-1-9
 * Time: 上午10:10
 */
require './vendor/autoload.php';
$string = new \EasySwoole\Spl\SplString('Hello, EasySwoole');
var_dump($string->split(5)->getArrayCopy());
/**
 * 输出结果过：
 * array(4) {
 *   [0]=>
 *   string(5) "Hello"
 *   [1]=>
 *   string(5) ", Eas"
 *   [2]=>
 *   string(5) "ySwoo"
 *   [3]=>
 *   string(2) "le"
 * }
 */
