Referencing for element in a PHP array -


जवाब $ सरणी नहीं है [0];

मेरा सरणी सेटअप है

<पूर्व> $ array = array (); $ सरणी [7] = 37; $ सरणी [1 9] = 98; $ सरणी [42] = 22; $ सरणी [68] = 14;

मैं सरणी को छांटा रहा हूं और छँटाई के बाद सबसे ज्यादा संभव मैच पाने की कोशिश कर रहा हूं। तो इस मामले में $ सरणी [1 9] = 98; मुझे केवल 98 मान की आवश्यकता है और यह हमेशा होगा सरणी के पहले स्थान पर। मैं $ सरणी [0] का उपयोग करके संदर्भ नहीं कर सकता क्योंकि 0 कुंजी मौजूद नहीं है। स्पीड की कमी का मतलब है कि मैं सर्वोच्च मैच खोजने के लिए सरणी के माध्यम से पाश नहीं कर सकता। 

  foreach ($ array as $ value ) {Echo $ value; टूटना; }

<पूर्व> $ keys = array_keys ($ array); एरे $ सरणी [$ कुंजी [0]];

या आप फ़ंक्शन का उपयोग कर सकते हैं: 

  रीसेट ($ सरणी); $ मान = वर्तमान ($ सरणी);
