title: ini_set not working
body: <p>Here is the matter:</p>
  
  <pre>
  ini_set('display_errors', '1');
  ini_set('safe_mode', '0');
  ini_set('allow_url_fopen', '1');
  ini_set('allow_url_include', '1');
  print_r(ini_get_all());
  </pre>
  
  <p>And I get:</p>
  
  <pre>
  Array(
      [allow_url_fopen] => Array
          (
              [global_value] => 1
              [local_value] => 1
              [access] => 4
          )
  
      [allow_url_include] => Array
          (
              [global_value] => 
              [local_value] => 
              [access] => 4
          )
  </pre>
  
  <p>Why I cannot set that variable within the php ini_set function? The directive is specified as PHP_INI_ALL then it can be defined within the ini_set() function!
