जब मैं अनुपालन कोड चलाऊँगा PHP में 

  यदि ('हाँ' == 0) 'एक' गूंज; Else गूंज 'बी';

आउटपुट एक है।
मुझे क्या हुआ समझ में नहीं आ रहा है? और मैं php कोड को सी स्रोत कोड में परिवर्तित कर सकता हूं कि क्या वास्तविक हो रहा है?

PHP है एक गतिशील रूप से टाइप की गई भाषा, और == एक ढीली तुलना ऑपरेटर है, जिसका अर्थ है कि यह सबसे पहले उसे एक प्रकार, int की तुलना में मूल्य डालेगा बात, और फिर उनकी तुलना; स्ट्रिंग को बायीं भाग से संख्यात्मक ले कर, पूर्णांक में डाली जा रही है, इसलिए 1abc को 1 को डाले जाते हैं। उस तर्क से हाँ को 0 में डालें, और 0 == 0 पैदावार true से।
