使用整数位置分解字符串

Question

我的意见是这样的:

$str = ' 1. Admin, Administrator,3. Visor, Super,4. Team, Super User,5. lastname, employee'

如何使用数组爆炸产生以下输出？

 array(
        [0] => Array ( [0] => 1 [1] => Admin [2] => Administrator)
        [1] => Array ( [0] => 3 [1] => Visor [2] => Super)
        [2] => Array ( [0] => 4 [1] => Team [2] => Super User)
        [3] => Array ( [0] => 5 [1] => lastname [2] => employee)
    )

Answer 1

<?php
$str = '1. Admin, Administrator,3. Visor, Super,4. Team, Super User,5. lastname, employee';
$str = str_replace('.', ',', $str);
$arr = explode(',', $str);
$arr = array_chunk ($arr, 3); 
var_export($arr);
