Hello,,

I have a new problem in my online store using open cart 1.4.8b.
It has been uploaded some days ago and I find no problem since I found this message above the header:

Warning: fread() [function.fread]: Length parameter must be greater than 0 in /home/xxxx/public_html/system/library/cache.php on line 27Warning: fread() [function.fread]: Length parameter must be greater than 0 in /home/xxxx/public_html/system/library/cache.php on line 27Warning: fread() [function.fread]: Length parameter must be greater than 0 in /home/xxxx/public_html/system/library/cache.php on line 27Warning: fread() [function.fread]: Length parameter must be greater than 0 in /home/gudangd/public_html/system/library/cache.php on line 27Warning: fread() [function.fread]: Length parameter must be greater than 0 in /home/xxxx/public_html/system/library/cache.php on line 27

* The xxx is the user of hosting

I don't know why it can be shown.
But that's very annoying.
I was trying to refresh, close my browser and open it again. But it has no result.

Can someone help me?

Thank's

Open

Code: Select all

/system/library/cache.php

Find

Code: Select all

    public function get($key) {
        $files = glob(DIR_CACHE . 'cache.' . $key . '.*');
        
        if ($files) {
            foreach ($files as $file) {
                  $handle = fopen($file, 'r');
                  $cache = fread($handle, filesize($file));
      
                  fclose($handle);

                  return unserialize($cache);
                }
        }
      }

and replace with

Code: Select all

    public function get($key) {
        $files = glob(DIR_CACHE . 'cache.' . $key . '.*');
        
        if ($files) {
            foreach ($files as $file) {
                  $cache = file_get_contents($file);
                  return unserialize($cache);
                }
        }
      }

This should really be how it's written in the first place to be honest

I agree.. In fact the php manual states it right on the page:
http://php.net/manual/en/function.file-get-contents.php

file_get_contents() is the preferred way to read the contents of a file into a string. It will use memory mapping techniques if supported by your OS to enhance performance.
