PHP: Replace city name -


I want to match an array against the string and want to change the name of the city in a string with a dash (-) For example: $ str = 'French tuition in New Yorker' or $ str = 'French Tuition New York'; $ ArrCity = array ('Newyork', 'Washington');

I want to change the following strings below, 

  $ str = 'French tuition - New York' and $ str = 'French tuition - New York ';   
 Thus if the last word is a city then it should be added before the dash (-). Or if the last word is the city and the last word is "IN", then "IN" should be replaced by a dash (-).   
 
 
 You can just do it with it.  
  & lt ;? Php $ str = 'French Tuition in New Yorker'; $ Str2 = 'French Tuition New York'; $ ArrCity = array ('Newyork', 'Washington'); $ Temp = array (); $ Partition = explosion ("", $ str); $ Last word = $ partition [count ($ partition) -1]; $ FirstListworld = $ partition [count ($ partition) -2]; If (in_array ($ lastword, $ arrCity)) (if (stroller ($ beforeLastWord) === 'in') {$ split [count ($ split) -2] = '-';} and {$ partition [count ($ Partition) -1] = '-'; array_push ($ partition, $ last word);}} echo fonts ("", $ partition);? & Gt;

ios - Does Core Data autoupdate a many to many relationship on saving -

I have used 2 database tables and core data / NSManagedObjects in SQLite: User is user_id name group (multiple groups) Group group_id title group members (multiple users) By using core data to save a group and adding users ( Add to group) as follows: group * cordata = zero; Cordata = [NSEntityDescription insertNewObjectForEntityForName: @ Managed Object Contains in "Groups": Reference]; Request = [NSFetchRequest fetchRequestWithEntityName: @ "user"]; Request.predicate = [NSPredicate predicateWithFormat: @ "user_id =% @", user_id]; Result = [reference executeFetchRequest: request error: & amp; Error]; CoreData.group_id = group_id Cordettitle = Title [Cordata AdGroupMailersObject: [Last objections result]]; Is it right to say that core data manages a user with multiple users and groups with the code above? Yes, if the relationships are in the form of each other's inverse relationship The inverse relationships are updated automaticall...

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
