Question

我的意见是：

$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);

Answer 2

这是另一种选择......这不是一种非常安全的获取数据的方法，但只要输入完全以这种格式完成，这就行了。主要的区别是这个修剪了空白。

你也可以使用另一个答案，然后在开始之前先做str_replace（''，''

$myString="1. Admin, Administrator,3. Visor, Super,4. Team, Super User,5. lastname, employee";
$myOutput=array();
$myFirstSplit = explode(",",$myString);
foreach($myFirstSplit  as $myKey=> $myVal){
    $myNextSplit=explode('.',$myVal);
    if(count($myNextSplit) > 1){
        $myOutput[$myKey]=array(trim($myNextSplit[0]),trim($myNextSplit[1]));
    }else{
        $myOutput[$myKey-1][]=trim($myNextSplit[0]);
    }
}
var_dump($myOutput);

Answer 3

另一个修改输出的解决方案，比srain的（不错）解决方案快一点：

$str = '1. Admin, Administrator,3. Visor, Super,4. Team, Super User,5. lastname, employee';
$tok = strtok($str, ".,");
$output = array();
while ($tok !== false) {
    $output[] = trim($tok);
    $tok = strtok(".,");
}
$output = array_chunk($output, 3);

echo '<pre>';
print_r($output);
