In C, you can get "words" in file with your code, but not in PHP. fscanf() between C and PHP is not identical when I made a simple test codes for both. It seems PHP's fscanf() advances file pointer to end of line while C's fscanf() must be done by programmers like fscanf(fp,"%*[^\n]"). In most cases, programmers want to move file pointer to the end of line. Maybe that's why PHP's fscanf() does this. We cannot expect PHP functions works just like C/C++/Java since it is different languange even is name of the function is the same. I guess what you want to do is getting all words from a file using fscanf(), but it seems it is not possible with PHP's fscanf(). (Or is it a bug? Anyone?) Functions that have the same name in C better to be behaive just like C in PHP for C programmers. (but may not be good for non-C programmers.) I'm relatively new to PHP, so I don't know historical reason why some functions does not behaive like C. I see a lot of differences PHP and C, I think this is the way it is. How about a start new thread if you still curious about fscanf() behaviour? Someone may be able to give better explaination.
