我有这样的数组。
Array
(
[0] => Array
(
[size] => 197602
[files] => Array
(
[0] => directory1
[1] => file1.jpg
)
)
[1] => Array
(
[size] => 274893
[files] => Array
(
[0] => directory1
[1] => file2.jpg
)
)
[2] => Array
(
[size] => 41
[files] => Array
(
[0] => directory2
[1] => file1.txt
)
)
[3] => Array
(
[size] => 41
[files] => Array
(
[0] => directory2
[1] => file2.txt
)
)
[4] => Array
(
[size] => 47
[files] => Array
(
[0] => directory2
[1] => sub-directory1
[2] => file1.txt
)
)
[5] => Array
(
[size] => 41
[files] => Array
(
[0] => directory2
[1] => sub-directory1
[2] => file2.txt
)
)
[6] => Array
(
[size] => 47
[files] => Array
(
[0] => directory2
[1] => sub-directory1
[2] => file3.txt
)
)
[7] => Array
(
[size] => 41
[files] => Array
(
[0] => file1.txt
)
)
[8] => Array
(
[size] => 47
[files] => Array
(
[0] => file2.txt
)
)
)
我使用了此代码段。
<?php
foreach($array as $x)
{
$path=implode('\\',$x['path']);
$files[$path]=$x['length'];
}
并获得了上述数组的简化版本。
Array
(
'directory1\file1.jpg' => 197602,
'directory1\file2.jpg' => 274893,
'directory2\file1.txt' => 41,
'directory2\file2.txt' => 41,
'directory2\sub-directory1\file1.txt' => 47,
'directory2\sub-directory1\file2.txt' => 41,
'directory2\sub-directory1\file3.txt' => 47,
'file1.txt' => 41,
'file2.txt' => 47
);
所以我的问题是如何从简化数组中获取原始数组，即第二个数组中的第一个数组。 ？
到目前为止，我已经尝试过了。<?php
$array = Array
(
'directory1\file1.jpg' => 197602,
'directory1\file2.jpg' => 274893,
'directory2\file1.txt' => 41,
'directory2\file2.txt' => 41,
'directory2\sub-directory1\file1.txt' => 47,
'directory2\sub-directory1\file2.txt' => 41,
'directory2\sub-directory1\file3.txt' => 47,
'file1.txt' => 41,
'file2.txt' => 47
);
print_r($array);
$new_array = array();
foreach($array as $path => $size){
if(strpos($path,'\\') !== false) {
//file is under a directory tree/structure
$directory_tree = explode('\\',$path);
$new_array[]['size'] = $size ;
$new_array[]['files'] = $directory_tree;
//last element in array is filename.
//print_r($directory_tree );
}else{
//its just file
$new_array[]['size'] = $size;
$new_array[]['path']= $path;
}
}
print_r($new_array);
但获取大小和文件的双重数组。
Array
(
[0] => Array
(
[size] => 197602
)
[1] => Array
(
[files] => Array
(
[0] => directory1
[1] => file1.jpg
)
)
[2] => Array
(
[size] => 274893
)
[3] => Array
(
[files] => Array
(
[0] => directory1
[1] => file2.jpg
)
)
[4] => Array
(
[size] => 41
)
[5] => Array
(
[files] => Array
(
[0] => directory2
[1] => file1.txt
)
)
[6] => Array
(
[size] => 41
)
[7] => Array
(
[files] => Array
(
[0] => directory2
[1] => file2.txt
)
)
[8] => Array
(
[size] => 47
)
[9] => Array
(
[files] => Array
(
[0] => directory2
[1] => sub-directory1
[2] => file1.txt
)
)
[10] => Array
(
[size] => 41
)
[11] => Array
(
[files] => Array
(
[0] => directory2
[1] => sub-directory1
[2] => file2.txt
)
)
[12] => Array
(
[size] => 47
)
[13] => Array
(
[files] => Array
(
[0] => directory2
[1] => sub-directory1
[2] => file3.txt
)
)
[14] => Array
(
[size] => 41
)
[15] => Array
(
[path] => file1.txt
)
[16] => Array
(
[size] => 47
)
[17] => Array
(
[path] => file2.txt
)
)
我该如何解决这个问题？
感谢
答案 0 :(得分：3)
您必须更改此代码段：
$new_array[]['size'] = $size ;
$new_array[]['files'] = $directory_tree;
到此：
$new_array[] = array('size' => $size, 'files' => $directory_tree);
同样对于“正文”案例：
$new_array[] = array('size' => $size, 'path' => $path);

或者，您可以创建一个回调：
function parse($arr)
{
return explode('\\', $arr);//process your array
}
然后在一行中完成：
$original = array_map('parse', $converted);
