今天在论坛里看到有个朋友的需求，见证csdn的版主都不愧是大牛的角色存在啊！！！保存起来，方便以后需要的时候使用。

字符串为：

vcD4KPHByZSBjbGFzcz0="brush:java;">1 = 光电鼠标 2 = 机械鼠标 3 = 没有鼠标 1.1 = 黑色光电鼠标 1.2 = 红色光电鼠标 1.2.1 = 蓝牙红色光电鼠标
版主解答为：

<?php
$s =<<< TXT
1 = 光电鼠标
2 = 机械鼠标
3 = 没有鼠标
1.1 = 黑色光电鼠标
1.2 = 红色光电鼠标
1.2.1 = 蓝牙红色光电鼠标
TXT;
  
$res = array();
foreach(preg_split("/[\r\n]+/", $s) as $r) {
  list($k, $txt) = explode(" = ", $r);
  $p =& $res;
  foreach(explode(".", $k) as $v) {
    if(! isset($p[$v])) $p[$v] = array("txt" => $txt, "child" => array());
    $p =& $p[$v]["child"];
  }
}
  
print_r($res);
?>

打印出来的数组为：

Array
(
    [1] => Array
        (
            [txt] => 光电鼠标
            [child] => Array
                (
                    [1] => Array
                        (
                            [txt] => 黑色光电鼠标
                            [child] => Array
                                (
                                )
  
                        )
  
                    [2] => Array
                        (
                            [txt] => 红色光电鼠标
                            [child] => Array
                                (
                                    [1] => Array
                                        (
                                            [txt] => 蓝牙红色光电鼠标
                                            [child] => Array
                                                (
                                                )
  
                                        )
  
                                )
  
                        )
  
                )
  
        )
  
    [2] => Array
        (
            [txt] => 机械鼠标
            [child] => Array
                (
                )
  
        )
  
    [3] => Array
        (
            [txt] => 没有鼠标
            [child] => Array
                (
                )
  
        )
