title: How to delete cakephp cached file by name or by name prefix?
body: <p>In cakephp 2.0 I cache some information getting from some service calls in file for individual users. Using individual user_id as a prefix of the cached file name, I cache the files under a custom cache configuration which saves in a folder under <strong>cache</strong> folder. </p>
  
  <p>Like, if the service name is <strong>get_user_info</strong> and the custom cache folder name is <strong>user_info</strong> then for a user say user_id:111, a file will be cached with name <strong>111_get_user_info</strong> in <strong>cache/user_info</strong>.</p>
  
  <p>If I need to remove the cached info for this user:111, I can't make that. Because <strong>Cache::clear(false, 'user_info')</strong> deletes all the cached files under <strong>cache/user_info</strong> and as a consequence other users cached info has removed as well.</p>
  
  <p>Can anybody suggest me how can I clear the cached file by using a prefix match?</p>
  
  <p>Thanks!</p>
