php解析ini格式的文件自带有两个函数parse_ini_file和parse_ini_string,本身是可以解析二维数组的,但是不支持二维以上,但是官方示例也给出了解析二维以上的函数如下
/** * 解析ini文件支持多维数组解析 * @link https://www.php.net/manual/zh/function.parse-ini-file.php#114842 * @param $file * @param false $process_sections * @param int $scanner_mode * @return array|false|mixed */ function parseIniStringMulti($iniString, $process_sections = false, $scanner_mode = INI_SCANNER_NORMAL) { $explode_str = '.'; $escape_char = "'"; // load ini file the normal way $data = parse_ini_string($iniString, $process_sections, $scanner_mode); if (!$process_sections) { $data = [$data]; } foreach ($data as $section_key => $section) { if (!is_array($section)) { continue; } // loop inside the section foreach ($section as $key => $value) { if (strpos($key, $explode_str)) { if (substr($key, 0, 1) !== $escape_char) { // key has a dot. Explode on it, then parse each subkeys // and set value at the right place thanks to references $sub_keys = explode($explode_str, $key); $subs =& $data[$section_key]; foreach ($sub_keys as $sub_key) { if (!isset($subs[$sub_key])) { $subs[$sub_key] = []; } $subs =& $subs[$sub_key]; } // set the value at the right place $subs = $value; // unset the dotted key, we don't need it anymore unset($data[$section_key][$key]); } // we have escaped the key, so we keep dots as they are else { $new_key = trim($key, $escape_char); $data[$section_key][$new_key] = $value; unset($data[$section_key][$key]); } } } } if (!$process_sections) { $data = $data[0]; } return $data; } $inistr=<<<eot [db_config] username=admin password=123456 [cache] redis[host]=127.0.0.127 redis[password]=123456 redis.domain[]=www.aaa.com redis.domain[]=www.bbb.com redis.domain[]=www.ccc.com file[path]=/www/data/ file[max_size]=1024 [app] debug=true trace=false [multi] foo.data.config.debug = true foo.data.password = 123456 [normal] foo = bar ; use quotes to keep your key as it is 'foo.with.dots' = true [array] foo[] = 1 foo[] = 2 [dictionary] foo[debug] = false foo[path] = /some/path [multi] foo.data.config.debug = true foo.data.password[] = 123456 foo.data.password[] = 123456 eot; $data=parseIniStringMulti($inistr,true); print_r($data); echo $data['cache']['redis']['host'].PHP_EOL; echo $data['cache']['redis']['password'].PHP_EOL;
上面函数为了测试方便,参数传的是INI字符串,实际使用中可自行修改的parse_ini_file
