How to get an associative array from a string?

Question

This is the initial string:-

NAME=Marco\nLOCATION=localhost\nSECRET=fjsdgfsjfdskffuv=\n

This is my solution although the "=" in the end of the string does not appear in the array

$env = file_get_contents(base_path() . '/.env'); // Split string on every " " and write into array $env = preg_split('/\s+/', $env); //create new array to push data in the foreach $newArray = array(); foreach($env as $val){ // Split string on every "=" and write into array $result = preg_split ('/=/', $val); if($result[0] && $result[1]) { $newArray[$result[0]] = $result[1]; } } print_r($newArray);

This is the result I get:

Array ( [Name] => Marco [LOCATION] => localhost [SECRET] => fjsdgfsjfdskffuv )

But I need :

Array ( [Name] => Marco [LOCATION] => localhost [SECRET] => fjsdgfsjfdskffuv= )

php.net/manual/en/function.parse-url.php try something with this function — Zeljka

This is what I get with the parse_url() function : Array ( [path] => NAME=Marco_LOCATION=localhost_SECRET=fjsdgfsjfdskffuv=_ ) — Marco

@Alive to Die I did not downgrade your answer. Why would you do that to my question? — Marco

You can use the limit parameter of preg_split to make it only split the string once

http://php.net/manual/en/function.preg-split.php

you should change

$result = preg_split ('/=/', $val);

to

$result = preg_split ('/=/', $val, 2);

Hope this helps

$string = 'NAME=Marco\nLOCATION=localhost\nSECRET=fjsdgfsjfdskffuv=\n'; $strXlate = [ 'NAME=' => '"NAME":"' , 'LOCATION=' => '","LOCATION":"', 'SECRET=' => '","SECRET":"' , '\n' => '' ]; $jsonified = '{'.strtr($string, $strXlate).'"}'; $array = json_decode($jsonified, true);

This is based on 1) translation using strtr(), preparing an array in json format and then using a json_decode which blows it up nicely into an array...

Same result, other approach...

You can also use parse_str to parse URL syntax-like strings to name-value pairs.

Based on your example:

$newArray = []; $str = file_get_contents(base_path() . '/.env'); $env = explode("\n", $str); array_walk( $env, function ($i) use (&$newArray) { if (!$i) { return; } $tmp = []; parse_str($i, $tmp); $newArray[] = $tmp; } ); var_dump($newArray);

Of course, you need to put some sanity check in the function since it can insert some strange stuff in the array like values with empty string keys, and whatnot.
