php - Error: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in -

इस सवाल का पहले से ही एक उत्तर है: < 33 उत्तरों 

  $ result2 =   Mysqli_query ($ con, "चयन करें * से a_option WHERE $ राशि 1 & gt; मूल्य"); जबकि ($ row2 = mysqli_fetch_array ($ result2)) {गूंज $ पंक्ति 2 ['कंपनी का नाम']। "" $ पंक्ति 2 ['उत्पाद का नाम']। ""। $ पंक्ति 2 ['मूल्य']; गूंज & lt; br / & gt; '; }   
 मूलभूत MySQL कमांड ठीक काम कर रहा है, लेकिन जब मैं परिशोधन खोज करने की कोशिश करता हूं तो यह पैरामीटर त्रुटि फेंकता है:  
  mysqli_fetch_array () पैरामीटर 1   
 में दिए गए mysqli_result, बुलियन को दिया जाता है, इसलिए केवल मुख्य कोड को पोस्ट करने के लिए डीबी के संबंध में किया जाता है।  
 कठिन है, उसी प्रश्न के इतने सारे उत्तर दिए गए हैं, कुछ कैसे इनके माध्यम से जाने के बाद मैं त्रुटि को हल नहीं कर पा रहा हूं।  
 क्या कोई एक बिंदु / त्रुटि यहाँ हल कर सकता है .... धन्यवाद !!   
 
 
 इस तरह से आपकी क्वेरी परिवर्तन में समस्या  
  SELECT * से a_option WHERE मूल्य & gt; $ Amount1;   
 यदि क्वेरी ठीक काम करती है, तो आपके कनेक्शन चर के साथ समस्या।
