问题描述
你好，我被卡住了，正在寻求帮助
Hello just looking for some help as I've gotten stuck
我有两个字符串:
C:\Users\Bob\My Documents
/Users/Bob/Documents
通过了
preg_split('/(?<=[\/\\\])(?![\/\\\])/', $string)
返回
Array
(
[0] => C:\
[1] => Users\
[2] => Bob\
[3] => My Documents
)
Array
(
[0] => /
[1] => Users/
[2] => Bob/
[3] => Documents
)
我需要
Array
(
[C:\] => Array
(
[Users] => Array
(
[Bob] => Array
(
[My Documents] => array()
)
)
)
)
Array
(
[/] => Array
(
[Users] => Array
(
[Bob] => Array
(
[Documents] => array()
)
)
)
)
并最终合并到
Array
(
[C:\] => Array
(
[Users] => Array
(
[Bob] => Array
(
[My Documents] => array()
)
)
)
[/] => Array
(
[Users] => Array
(
[Bob] => Array
(
[Documents] => array()
)
)
)
)
(正确合并，而不只是附加，所以如果另一个字符串以 C:\Users\Dan 开头，那么 dan 将出现在 ?3rd? 维度上.array_merge_recursive() ? )
(properly merged, not just appended, so if another string started with C:\Users\Dan Then dan would appear on the ?3rd? Dimension. array_merge_recursive() ? )
推荐答案
只需使用 preg_split() 返回的数组并从中构建树结构即可:
Just take the arrays returned by preg_split() and build your tree structure out of them:
$tree = array();
foreach ( $strings as $string ) {
$path = preg_split( '/(?<=[\/\\\])(?![\/\\\])/', $string );
$ptr =& $tree;
foreach ( $path as $elem ) {
if ( ! array_key_exists( $elem, $ptr ) )
$ptr[ $elem ] = array();
$ptr =& $ptr[ $elem ];
}
}
