php - 如何从字符串中获取关联数组？

Question

这是初始字符串:-

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

这是我的解决方案，虽然字符串末尾的“=”没有出现在数组中

$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);

这是我得到的结果:

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

但我需要:

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

Answer 1

可以使用preg_split的limit参数让它只分割一次

你应该改变

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

到

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

希望对你有帮助
