Turn string to nested array php - php

Question

I am trying to turn a string into a nested array
Here is my string:
a/b/d.docx
and I wanted to be like this:
array(
"name" => "a",
"type" => "folder",
"sub" => array(
"name" => "b",
"type" => "folder",
"sub" => array(
"name" => "c.docx",
"type" => "file",
"size" => "20"
)
)
)
This is the code that I have so far
$items = explode('/', $strings);
$num = count($items);
$num = --$num;
$temp = array();
foreach($items as $keys => $value) {
$temp[$keys] = array(
"name" => $value,
"type" => "folder",
"items" => $temp[++$keys]
);
if($keys == $num){
$temp[$keys] = array(
"name" => $value,
"type" => "file",
"size" => "20"
);
}
}
var_dump($temp);
I am trying this functions but this only turn string into a single array and it also can't do the 'items' line.
Any help would be appreciated.Thanks.
Note that the path is virtual and doesn't exist.
UPDATE: How can I add path to each array??for example,"path"=>"a/b"

Answer 1

You can do that:
$path = 'a/b/d.docx';
$parts = explode('/', $path);
$result = [ 'name' => array_pop($parts), 'type' => 'file', 'size' => 20 ];
while ($parts) {
$result = [ 'name' => array_pop($parts), 'type' => 'folder', 'sub' => $result ];
}
print_r($result);

<?php
$strings='a/b/d.docx';
$items = explode('/', $strings);
$num = count($items)-1;
$root= array();
$cur = &$root;
$v='';
foreach($items as $keys => $value) {
$v = $v.$value;
$temp = array( "name" => $value, "path"=>$v, "type" => "folder", "items" => "");
if($keys == $num){
$temp = array( "name" => $value, "path"=>$v, "type" => "file", "size" => "20");
}
$v= $v.'/';
if($keys==0) {
$cur = $temp;
}
else
{
$cur['items'] = $temp;
$cur = &$cur['items'];
}
}
var_dump($root);

Try recursion:
public function testAction(){
$sString = 'a/b/c/d.exe';
$aExploded = explode('/', $sString);
var_dump($this->_parse_folder_rec($aExploded));
}
private function _parse_folder_rec($aExploded){
$aResult = [];
$aResult['name'] = array_shift($aExploded);
if($aExploded){
$aResult['type'] = 'folder';
$aResult['sub'] = $this->_parse_folder_rec($aExploded);
}else{
$aResult['type'] = 'file';
$aResult['size'] = 20;
}
return $aResult;
}
