I want to create a singleton class that read multidimensional array from txt file and flatten the array retrieved. This is what I have tried so far: class singleton { protected static $instance = null; public static function getInstance() { if (!isset(static::$instance)) { static::$instance = new static; } return static::$instance; } public static function flattenArray($array) { $return = array(); $iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($array)); foreach ($iterator as $value) { $return[] = $value; } return $return; } public static function loadFile($path) { $file_handle = fopen($path, "r"); while (!feof($file_handle)) { $line = fgets($file_handle); $rawarray[] = $line; } $flattedarray = self::flattenArray($rawarray); fclose($file_handle); return $flattedarray; } With the txt file containing: array('a', 'b', array(array('c'), 'd'), 'e', array('f'), 'g') I run the class with: include 'singleton.php'; $singleton = singleton::getInstance(); $flattedarray = $singleton->loadFile("file.txt"); echo '<pre>'; print_r($flattedarray); echo'</pre>'; I get as a result: Array ( [0] => array('a', 'b', array(array('c'), 'd'), 'e', array('f'), 'g') ) Which is the same array found in the txt file. how can i do it without using eval. What am I doing wrong ?
