MySQL and PHP - Get last comments from database -

-

मेरे पास यह कोड है: 

  $ sql = "SELECT * DEPTMENTMENT WHERE DEPTEDID = '$ PostID' ORDER BY deptCommentRegDate एएससी, deptCommentRegTime ASC LIMIT 4 ";   
 यह काम कर रहा है लेकिन यह केवल एक विशेष पोस्ट की पहली 4 टिप्पणियों को प्राप्त करता है। एएससी आदेश में अंतिम 4 टिप्पणियाँ पाने के लिए मुझे इस कोड की आवश्यकता है। क्या यह संभव है।  
 किसी भी मदद की सराहना की।   
 
 
 कोशिश करें  < पूर्व>  $ sql = "SELECT * FROM DEPTMENTMENT WHERE DEPPITID = '$ POSTID' ORDER BY DEPTMENTMENTRegDate एएससी, DEPTMENTRegTime DESC LIMIT 4";   
 ... और उसके बाद  array_reverse ();  परिणाम पर चलाते हैं।  
 
 जब भी मुझे आपके पास है, तो मुझे लगता है कि आप अपनी क्वेरी इस तरह से तैयार कर रहे हैं कि यह सुझाव देता है कि आप उसे  mysql _ *  प्रकार फ़ंक्शन पर पास करने का इरादा रखते हैं। कृपया ध्यान रखें कि इन प्रकार के कार्यों को नापसंद किया गया है, और आपको सलाह दी जाती है कि पुस्तकालय जैसे   को इसके बजाय डेटाबेस से संवाद करने के लिए।
