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>

I am trying to create a GUI with a plot and a slider. The slider should be described as continuously and output. I have a problem with this explanation that the uicontrol object is programmatically created, on the contrary, I want to know that in the last three instances, to complete the same thing done according to the program What can be added to a GUI file that is created. The code is down, and I have marked the (wrong) code that is provided by some of the above examples. Thanks a lot for any help! This slider function sets P1_slider_Callback (hObject, eventdata, handle) (handle, dragon, 'string', num2str (get (hObject, 'value'), 3)) PlottheData_Callback ( HOBject, EventData, Handle)% "PlotHeadata" is a button that creates the data slider based on the value of P1_slider%, and I think that here "p1_slider_CreateFcn" (hObject, eventdata, handle) needs to be assembled (HOBJECT, 'BackgroundRoller'), (0, 'Default UITTACKBACK MANDROLLE...
