php एमपी 3 स्ट्रिंग त्रुटि

Question

मेरे पास मेरी साइट के लिए एमपी 3 पढ़ने के लिए एक एमपी 3 कक्षा है। (मैं एक साझा होस्टिंग के बाद से मॉड्यूल स्थापित नहीं कर सकता)। मैं एमपी 3 अपलोड करता हूं और फिर सिस्टम ने मेरी कक्षा का उपयोग करके इसे पढ़ा और मेरे mysql फ़ाइल नाम और स्थान, और मूल टैग (कलाकार, गीत का नाम, एल्बम) में डाला। mysql डालने ठीक है, लेकिन मुझे स्ट्रिंग्स के साथ समस्या है जो मैं डाल रहा हूं।

Array 
(
    [genre] => ��Rock 
    [title] => ��Walk 
    [artist] => ��Foo Fighters 
    [album] => ��Wasting Light

क्या मेरी कोड के साथ गलत है: मैं इस मिलता है, अब http://pastebin.com/fXsm0c3T

जब मैं मूल्य पढ़ें:

यहाँ मेरी कोड है?

Answer 1

आपके कोड के आधार पर, $ मूल्य को ट्रिम या यूटीएफ में परिवर्तित करने की आवश्यकता है (मैं यूटीएफ में परिवर्तित करना पसंद करता हूं)। मैं समारोह की जाँच करेगा कि जो UTF एमपी 3 है और इसे सही ढंग से पार्स कहा: यहाँ

$value = $this->filter($value, $tag); // convert to UTF or else that is why you have weird chars 

एक readable code है।
