问题 Seems the file keeps adding 0x0D to my saved binary files no matter what setting I put in the fopen mode flag. It's not only affecting fopen / fwrite .. but also file_put_contents . file_get_contents I thought was the problem to begin with.. but it turns out this one is actually working okay.. because when I dumped the file using bin2hex() it came out good. I was blaming at first the std::string in C++ for this bug.. but it turns out it doesn't even have anything to do with C++ but it's in

问题 I was wondering what happens if multiple scripts are sharing same file. I uploaded the test on remote server, where they use HDD to store data. There were 7 tests total, but the family of 6 are compatible. I have 7 files of different size which I uploaded to server and the test. It is loop which reads and writes data from the files.
