How do I get an associative array from a string?
This is the starting line: -
NAME=Marco\nLOCATION=localhost\nSECRET=fjsdgfsjfdskffuv=\n
This is my solution, although the "=" at the end of the line 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);
As a result, I get:
Array ( [Name] => Marco [LOCATION] => localhost [SECRET] => fjsdgfsjfdskffuv )
But I need:
Array ( [Name] => Marco [LOCATION] => localhost [SECRET] => fjsdgfsjfdskffuv= )

You can use the prefix parameter preg_split so that it splits the string only once
http://php.net/manual/en/function.preg-split.php
you must change
$result = preg_split ('/=/', $val);
to
$result = preg_split ('/=/', $val, 2);
Hope it 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) translating using strtr (), preparing the array in json format, and then using json_decode, which brings it into the array well ...
Same result, different approach ...

You can also use parse_str to parse URL syntax strings for 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 checking in the function, as it might insert some weird stuff into the array like values with empty string keys and whatnot.
