गतिशील पंक्तियों के साथ डेटाबेस से डेटा कैसे दिखाएं

सबसे पहले मेरी खराब अंग्रेजी के लिए खेद है।

आपकी क्वेरी में, id_location . द्वारा ऑर्डर करने के बजाय , घटक के नाम से आदेश दें . इस तरह आप डायनामिक रोस्पैन को आसानी से जोड़ सकते हैं। मैंने आपका कनेक्शन प्रोग्राम नहीं बदला है, लेकिन मैंने आपका दूसरा भाग बदल दिया है। कृपया जांचें। मुझे पता है कि 3 से 4 लूप हैं। लेकिन अगर किसी शरीर को बेहतर अहंकार मिले तो कृपया मुझे बताएं।

    $location++;
