pcre - Match or remove string that occurs multiple times within two strings with regex -


I have a large CSV export where the columns do not align because some values ​​are accidentally inserted into multiple cells instead of one Fortunately, the price is between two unique stars, I am hoping to use regex to merge these values ​​into one cell. Sample data is as follows: 

  "apple", "tap", "0", "0", "0", ",", "1", ",", "fruit" , "0", "0", "0", ",", "1", ",", ",", ",", "," "red", "sweet", "d $", " Object "" horse "," tap "," 0 "" 1 "," 0 "," 0 "," 0 "," 0 "," 0 "," 0 "," 0 ","  "Zero", "0", "0", "0", ",", "1", ",", "  
  
 And the end of unearned values ​​ 
  "," $ d $ "  
 I'm trying to find a regex The "," "0", "0", "0", ",", "1", ",", and "the", which will be removed in order to merge between those values, "Fruit, Red," D "," D "," Object "," Horse ", "Faucet", "0", "0", "0", ",", "1", ",", "animal, big, tail", "d", "object" "los angeles", "null "," 0 "," 0 "," 0 ",", "," 1 ",", "," city, california, blurry, entertainment "," d $ "," location "   
 
 
 You can do this:   '$ pattern =' (? : "NULL", "0", "0", "0", "", "1", "", "| \ g) [^ (^ ?!)"] \ Kashmir "," (?! D \ $) ~ '; $ Csv = preg_replace ($ pattern, ',', $ csv);   
 Pattern details:  
  ~ # delimiter (?: "NULL", "0", "0", "0", ",", "1", ",", "| (?! ^) \ G # Anchor for the end of the last match) [^" Content between the # quotes # Kashmir # removes all the left from the match result "," # "," Is not followed by "," (?! D! $) #df ~ $ /   
  meaning "anchor" which means "string" The beginning of "or" the end of the last match "I added the  (?! ^ ^)  to avoid the first case  
  An entry point for the first match, "NULL", "0", "0", "0", ",", "1", ",", " The content between the quotes is matched, since  \ K  removes all from the left side of the match result, only  ","  is changed.  
 In the next matches, the use of  \ G  as the entry point and continues in the nearest matches until ?! D \ $)  is successful.

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
