How to group an array by specific value?
2
I have an array like this:
$files = array(
"Input.txt" => "Randy",
"Code.py" => "Stan",
"Output.txt" => "Randy"
);
I want to group the file by its owner and returned like this:
[
"Randy" => ["Input.txt", "Output.txt"],
"Stan" => ["Code.py"]
]
I tried to do it like this:
<?php
class FileOwners
public static function groupByOwners($files)
foreach ($files as $file => $owner)
$data[$owner] = $file;
;
return $data;
$files = array(
"Input.txt" => "Randy",
"Code.py" => "Stan",
"Output.txt" => "Randy"
);
var_dump(FileOwners::groupByOwners($files));
But what I got is this:
array(2)
["Randy"]=>string(10) "Output.txt",
["Stan"]=>string(7) "Code.py"
Please help how to make it.

you are overriding $data, use $data[$owner] = $file; instead of $data[$owner]= $file;
public static function groupByOwners($files)
foreach ($files as $file => $owner)
$data[$owner] = $file;
;
return $data;

Just create a multidimensional array ,
foreach ($files as $file => $owner)
$data[$owner] = $file; // will store values as an array inside the key
// Remove semicolon from here
