INI file for multidimensional array in PHP

Question

I have the following INI file:

abc = 1 abde = 2 

I am parsing this file using parse_ini_file. And it returns:

 array( 'abc' => 1, 'abde' => 2 ) 

But I want to create a multidimensional array. My output should be:

 array( 'a' => array( 'b' => array( 'c' => 1, 'd' => array( 'e' => 2 ) ) ) ) 

Thanks in advance.

Answer 1

This is how I see it:

 <?php class ParseIniMulti { public static function parse($filename) { $ini_arr = parse_ini_file($filename); if ($ini_arr === FALSE) { return FALSE; } self::fix_ini_multi(&$ini_arr); return $ini_arr; } private static function fix_ini_multi(&$ini_arr) { foreach ($ini_arr AS $key => &$value) { if (is_array($value)) { self::fix_ini_multi($value); } if (strpos($key, '.') !== FALSE) { $key_arr = explode('.', $key); $last_key = array_pop($key_arr); $cur_elem = &$ini_arr; foreach ($key_arr AS $key_step) { if (!isset($cur_elem[$key_step])) { $cur_elem[$key_step] = array(); } $cur_elem = &$cur_elem[$key_step]; } $cur_elem[$last_key] = $value; unset($ini_arr[$key]); } } } } var_dump(ParseIniMulti::parse('test.ini')); 

Answer 2

This is actually quite simple, you only need to change the format of the array that you already have, breaking its key:

 $ini_preparsed = array( 'abc' => 1, 'abde' => 2 ); $ini = array(); foreach($ini_preparsed as $key => $value) { $p = &$ini; foreach(explode('.', $key) as $k) $p = &$p[$k]; $p = $value; } unset($p); print_r($ini); 

Conclusion:

 Array ( [a] => Array ( [b] => Array ( [c] => 1 [d] => Array ( [e] => 2 ) ) ) )

Take a look at the Zend_Config_Ini class. It does what you want, you can use it autonomously (without the rest of the Zend Framework), and as a bonus, it supports section inheritance.

Using the toArray method, you can create an array from a configuration object.

Answer 4

Take a look at PHProp .

Similar to Zend_Config_Ini , but you can refer to a key in your configuration, for example ${key}

Answer 5

This is my class for parsing ini files in a multidimensional array:

 class Cubique_Config { const SEPARATOR = '.'; private static $_data = null; public static function get() { if (is_null(self::$_data)) { $commonIniFile = APP . '/config' . '/common.ini'; $envIniFile = APP . '/config' . '/' . ENV . '.ini'; if (!file_exists($commonIniFile)) { throw new Exception('\'' . $commonIniFile . '\' config file not found'); } if (!file_exists($envIniFile)) { throw new Exception('\'' . $envIniFile . '\' config file not found'); } $commonIni = parse_ini_file($commonIniFile); $envIni = parse_ini_file($envIniFile); $mergedIni = array_merge($commonIni, $envIni); self::$_data = array(); foreach ($mergedIni as $rowKey => $rowValue) { $explodedRow = explode(self::SEPARATOR, $rowKey); self::$_data = array_merge_recursive(self::$_data, self::_subArray($explodedRow, $rowValue)); } } return self::$_data; } private static function _subArray($explodedRow, $value) { $result = null; $explodedRow = array_values($explodedRow); if (count($explodedRow)) { $firstItem = $explodedRow[0]; unset($explodedRow[0]); $result[$firstItem] = self::_subArray($explodedRow, $value); } else { $result = $value; } return $result; } }
