Related function description:

fopen() The function opens a file or URL. If fopen() fails, it returns FALSE with an error message. You can hide error output by adding an '@' in front of the function name.

fwrite() The function writes the contents to an open file. The function will stop running when it reaches the specified length or reaches the end of file (EOF), whichever comes first. If the function executes successfully, the number of bytes written is returned. On failure, returns FALSE.
