Sets write file buffering on the given stream
Syntax
stream_set_write_buffer ( resource $stream , int $buffer ) : int
Parameters
streamThe file pointer.
bufferThe number of bytes to buffer. If buffer is 0 then write operations are unbuffered. This ensures that all writes with fwrite() are completed before other processes are allowed to write to that output stream.
Return
Returns 0 on success, or another value if the request cannot be honored.
Examples

$filename = $_SERVER["DOCUMENT_ROOT"] . "/assets/txt/file.txt";
