[Populate array with recursive function]

@benanamen The problem is solved already. I tried to sort a table by php. So depending on which column i wanted to sort the key values changed.

You can find the full code here (Github). It's the first function in this file and the page file list_all.php uses those function in get_cards.php

 

And i include my attempts as i just started to learn php this week and i might do a lot of mistakes or just don't know it better atm. This way more experienced users can give me some hints as they can identify the problem like @gw1500se and @Barand did

[Populate array with recursive function]

Ok i got it now to work with:

if ($key != ""){
  $key = $key." ";
  if (!isset($sort_list[$key])){
  	$sort_list[$key] = [];
  }
  $sort_list[$key][sizeof($sort_list[$key])] = array($info_1, $info_2, strval($info_3), $path, $filename);
}

I used the $key = $key." " statement as my keys could be numbers (negative and positive) or strings. If i didn't do this any integer would be interpreted as array position instead of array key

I also rewrote the function

function get_all_data($filename, &$output, &$binary, &$sort_list, $depth=0) {
    if ($sort_list == NULL && $depth == 0) {
        $sort_list = array();
    }
    $depth++;
    if (is_dir($filename) && $filename != "." && $filename != "..") {
        $dir_content = glob("$filename/*");
        foreach ($dir_content as $f) {
            get_all_cards($f, $output, $binary, $sort_list, $depth);
        }
    }
    else {
        if (is_file($filename)){
			stuff ... 

 

[Populate array with recursive function]

Thx @gw1500se & @Barand

So far i get a step closer to my target array by populationg the array with this:

$sort_list = array_merge(
	$sort_list, 
	array(
		$key => array(
			$counter => array(
				$information_1, 
				$informatin_2, 
				$informatino_3, 
				$main_dir, 
				$file
			)
		)
	)
);

But the finished array is still not in the structure i want to have

Example Output:

array(7) { 
    [key1]=> array(1) { 
        [0]=> array(5) { 
            [0]=> string(6) info_1 
            [1]=> string(27) info_2 
            [2]=> info_3 
            [3]=> string(15) info_4 
            [4]=> string(36) info_5 
        } 
    } 
    [key2]=> array(1) { 
        [0]=> array(5) { 
            [0]=> string(6) info_1 
            [1]=> string(27) info_2 
            [2]=> info_3
            [3]=> string(15) _info_4 
            [4]=> string(36) info_5 
        } 
    } .....

For the first sight this output looks like i want it. but if i have identical keys this will not work anymore. It's just saving 1 entry for each key. Is the array_merge function the right way to go for this task?

 

@Barand depending on the keys i use but the problem in my case is similar to a recursive directory search but a little bit different. In my case i get data from different directories at different times so i can't add all the values or arrays of each directory in one go. But thanks for the &$variable hint . I'll rewrite my function and try it this way.

[Populate array with recursive function]

edit:

the else statement in the function is a elseif statement which checks if $main_dir.$file is a file which matches the pattern of files i'm looking for

elseif (is_file($main_dir.$file) && other checks) {
	... populate array
}

 

[Populate array with recursive function]

Hey there

I just started out with PHP so it might be a trivial problem. I want to populate an array with values by a recursive function but i don't get it the way i want it to have.

Target array (written in python syntax):

myArray = { 
	key : [
		[a1, a2, a3, a4], 
		[b1, b2, b3 ,b4]
	],
	key2 : [
		[c1, c2, c3, c4], 
		[d1, d2, d3, d4]
	]
}

So far i created a recursive function to collect all data i need for the array but i don't get the right syntax to achieve my target array.

What i have so far is following code (snippet):

function get_data($main_dir, $items=[], $myArray=[], $depth=0) {
	global $items;
	if ($myArray == NULL && depth == 0) {
		$myArray = array();
	}
	$depth++;
	$dirHandle = opendir($main_dir);
	
	while ($file = readdir($dirHandle)){
		if(is_dir($main_dir.$file) && $file != "." && $file != "..") {
			$new_dir = $main_dir.$file."/";
			$items = get_data($new_dir, $items, $myArray, $depth);
			$myArray = $items[1]
			$items = $items[0]
		}
		else {
			splitted_dir = preg_split("/\//", $main_dir);
			key = splitted_dir[2];
			file_information = read_out_file($main_dir.$file);
			information_1 = file_information[0];
			information_2 = file_information[1];

			myArray = array_merge($myArray, array($key, array($key, $information_1, $information_2, $main_dir, $file))
		}
	}
}

The array contains all informations i need but the structure of it is not useable.

Current output:

Array ( 
	[0] => key1 
	[1] => Array ( 
		[0] => key1 
		[1] => information_1 
		[2] => information_2 
		[3] => ./path/ 
		[4] => filename ) 
	[2] => key1 
	[3] => Array ( 
		[0] => key1 
		[1] => information_1
		[2] => information_2
		[3] => ./path/ 
		[4] => filename ) 
	[4] => key1 
	[5] => Array ( 
		[0] => key1 
		[1] => information_1
		[2] => information_2 
		[3] => ./path/ 
		[4] => filename ) 
	[6] => key2 
	[7] => Array ( 
		[0] => key2 
		[1] => information_1
		[2] => information_2
		[3] => ./path/ 
		[4] => filename ) 
	[8] => key2 
	[9] => Array ( 
		[0] => key2 
		[1] => information_1 
		[2] => information_2 
		[3] => ./path/ 
		[4] => filename ) 
) 1 

## IDK why this "1" at the end gets printed out... 

But what i want to get is this:

Array (
    [key1] => Array (
        Array (
            [0] => key1 
            [1] => information_1 
            [2] => information_2 
            [3] => ./path/ 
            [4] => filename ) 
        )
        Array (
            [0] => key1 
            [1] => information_1 
            [2] => information_2 
            [3] => ./path/ 
            [4] => filename ) 
        )
    )
    [key2] => Array (
        Array (
            [0] => key2 
            [1] => information_1 
            [2] => information_2 
            [3] => ./path/ 
            [4] => filename ) 
        )
        Array (
            [0] => key2 
            [1] => information_1 
            [2] => information_2 
            [3] => ./path/ 
            [4] => filename ) 
        )
    )
)

 

At the end i want to sort the output by alphabetic order of the keys which i should achieve with sort() i guess?

 

Greetings
