Put ALL of the fopen()'s AND fread()'s before the while loop.
Put ALL of the fwrite()'s AND (unnecessary) fclose()'s after the end of the while
loop.
The only thing you should be doing inside the loop is searching/replacing. The while
aspect will automaticall bring up the next names to be searching for.
That for loop shouldn't be there...

The odd replacement is due to the itterations for each record in the csv file caused
by mistakenly using that for loop. Ditch it.
