Any chance you can update this to be loaded via composer?

Thanks for all you do for PHP.

The method $this->cache->delete_all() deletes all the files in the folder including the .htaccess and the index.html files which are necessary for security purposes.

Hello mate,

I'm using your lib widely - it's nice.
But files created with library, can't be somehow deleted, their chmod shows 777, but still no luck...
don't you know what can be an issue?

Thanks!

I think I'm possibly just being a bit dim here, but I can't seem to get query results to store in cache files.
Here's the exact problem I'm having:

Upon running the database query, a cache file is created but the results from the database are not stored in it.
To add to my confusion, the results appear on the page upon first load, but then after a refresh, the cached file is then loaded instead, so no data is retrieved.

Here’s my controller - users.php

class Users extends CI_Controller {

 public function test()
 {
  $this->output->enable_profiler(TRUE);
  $this->load->model('mdl_users');

  $id = 2;
  $data['query'] = $this->cache->model('mdl_users', 'get_user', array($id), 120);
  
  $this->load->view('users', $data);
 }

} 

My model - mdl_users.php

class Mdl_users extends CI_Model {

 function get_user($id)
 {
  $this->db->where('id', $id);
  $this->db->limit(1);
  $query=$this->db->get('users');
  return $query;
 }
 
}

and my view - users.php

 foreach($query->result() as $row)
 {
  echo $row->name;
 }

And this is what is stored in the cache file

a:4:{s:16:"__cache_contents";O:19:"CI_DB_mysqli_result":8:{s:7:"conn_id";O:6:"mysqli":19:{s:13:"affected_rows";N;s:11:"client_info";N;s:14:"client_version";N;s:13:"connect_errno";N;s:13:"connect_error";N;s:5:"errno";N;s:5:"error";N;s:10:"error_list";N;s:11:"field_count";N;s:9:"host_info";N;s:4:"info";N;s:9:"insert_id";N;s:11:"server_info";N;s:14:"server_version";N;s:4:"stat";N;s:8:"sqlstate";N;s:16:"protocol_version";N;s:9:"thread_id";N;s:13:"warning_count";N;}s:9:"result_id";O:13:"mysqli_result":5:{s:13:"current_field";N;s:11:"field_count";N;s:7:"lengths";N;s:8:"num_rows";N;s:4:"type";N;}s:12:"result_array";a:0:{}s:13:"result_object";a:0:{}s:20:"custom_result_object";a:0:{}s:11:"current_row";i:0;s:8:"num_rows";i:1;s:8:"row_data";N;}s:15:"__cache_created";i:1401965162;s:20:"__cache_dependencies";a:0:{}s:15:"__cache_expires";i:1401965182;} 

I'm testing this on a vanilla install for now, but the site I'm intending to use this on could potentially be running hundreds of queries per second, so this would be brilliant if I can get it working!

Thanks for any help!

This occurred while ApacheBench was running a benchmark (100 cycles). I think it detected the cache was old and attempted to delete it multiple times (race condition?). Possibly fixable with flock?
