php - Ignore if specific character matched -

-

मेरे पास एक स्ट्रिंग है: 

  $ str = "yellow; yellow \; er; yellowest ";

और मैं इस तरह preg_split का उपयोग करता हूं: 

  preg_split ("/; /", $ str);

लेकिन मैं इस तरह से परिणाम प्राप्त करना चाहता हूं: 

  सरणी ("पीले", "पीले; एर", "पीले")

लेकिन परिणाम सही नहीं है।

तो वास्तव में मैं क्या करना चाहता हूं, यह स्ट्रिंग को पर विभाजित करना है; लेकिन अगर ; उसके पास एक \ है, उसे बस रहना होगा; , \ को हटा दें और इसे वहां विभाजित नहीं किया जाएगा इसलिए इसे पर विभाजित करना पड़ता है; लेकिन \; नहीं है और अगर कोई \; है तो उसे \ चरित्र तारों के साथ कुछ ऐसा होता है: 

  "नमस्कार वहाँ \" जैक्स \ "" गूंज;   
   
   
 हैलो वहाँ    
 
 
 आप यह सुनिश्चित करने के लिए एक नकारात्मक नजरिए का उपयोग कर सकते हैं कि ;  एक  \  
 
  preg_split ('/ (? & Lt;! \\\); /', $ str) से पहले नहीं है < / कोड>
