The code will be as follows:8$has = new Has();9echo $has->stream_get_contents();10$has = new Has();11echo $has->stream_get_contents();12$has = new Has();13echo $has->stream_get_contents();14The above code will not work as expected. It will print the data from the first file only. This is because the data is already read from the stream and is not available for the next file to read. To avoid this, you need to use stream_seek() function to reset the pointer to the start of the stream before reading the data from the stream. The code will be as follows:15$has = new Has();16$has->stream_seek(0);17echo $has->stream_get_contents();18$has = new Has();19$has->stream_seek(0
