Last week I had an email from Blaise , the administrator of – this site is about OpenSource software and tutorials in lots of languages – he asked me via email to translate the phpsyslog-ng tutorial to Persian and I eagerly done it . you can find the Persian translation in this address .

40 Tips for optimizing your php Code
