本文实例陈诉了PHP parse_ini_file函数的应用与扩展操作。分享给各人供各人参考,详细如下:
parse_ini_file($filename, $process_sections = false, $scanner_mode = INI_SCANNER_NORMAL)解析一个设置文件。
filename要解析的文件名;
process_sections设置为true时,得到一个多维数组,包括设置文件中每一节的名称和设置,默以为false;
解析乐成返回关联数组,失败返回false。列举一下官网的例子,也引用了官网的扩展实例
  1. parse_ini_file_multi()
复制代码

下面是设置文件内容:
  1. [first_section]
  2. one = 1
  3. two = 2
  4. name = test
  5. [second_section]
  6. path = '/tmp/test'
  7. url = 'http://test.com/login.php'
  8. [third_section]
  9. php_version[] = '5.0'
  10. php_version[] = '5.1'
  11. php_version[] = '5.5'
  12. [dictionary]
  13. foo[debug] = true
  14. foo[path] = /some/path
  15. [fourth_section]
  16. fold1.fold2.fold3 = 'a'
  17. fold1.fold2.fold4 = 'b'
  18. fold1.fold2.fold5 = 'b'
复制代码
下面是PHP文件内容:
  1. function parse_ini_file_multi($file, $process_sections = false, $scanner_mode = INI_SCANNER_NORMAL){
  2. $explode_str = '.';
  3. $escape_char = "'";
  4. $data = parse_ini_file($file, $process_sections, $scanner_mode);
  5. if (!$process_sections) {
  6.   $data = array($data);
  7. }
  8. foreach ($data as $section_key => $section) {
  9.   foreach($section as $key => $value){
  10.    if(strpos($key, $explode_str)){
  11.     if(substr($key, 0, 1) !== $escape_char){
  12.      $sub_keys = explode($explode_str, $key);
  13.      $subs =& $data[$section_key];
  14.      echo "\r\n".'========='."\r\n";
  15.      print_r($subs);
  16.      print_r($data);
  17.      foreach($sub_keys as $sub_key){
  18.       if (!isset($subs[$sub_key])) {
  19.        $subs[$sub_key] = [];
  20.       }
  21.       $subs =& $subs[$sub_key];
  22.       echo "\r\n".'++++++++'."\r\n";
  23.       print_r($subs);
  24.       print_r($data);
  25.      }
  26.      $subs = $value;
  27.      echo "\r\n".'----------'."\r\n";
  28.      print_r($subs);
  29.      print_r($data);
  30.      unset($data[$section_key][$key]);
  31.     }else{
  32.      $new_key = trim($key, $escape_char);
  33.      $data[$section_key][$new_key] = $value;
  34.      unset($data[$section_key][$key]);
  35.     }
  36.    }
  37.   }
  38. }
  39. if (!$process_sections) {
  40.   $data = $data[0];
  41. }
  42. return $data;
  43. }
  44. $arr = parse_ini_file('file.ini');
  45. print_r($arr);
  46. echo "\r\n".'================='."\r\n";
  47. $arr = parse_ini_file_multi('file.ini',true);
  48. echo "\r\n".'================='."\r\n";
  49. print_r($arr);
