note 117578 added to function.feof

From washington dot edu css342: On unix/linux, every line in a file has an End-Of-Line (EOL) character and the EOF character is after the last line. On windows, each line has an EOL characters except the last line. So unix/linux file's last line is stuff, EOL, EOF whereas windows file's last line, if the cursor is on the line, is stuff, EOF So set up data files on windows to be the same as on unix/linux. This way, you will correctly determine eof under both unix/linux and windows. In general, you must exit all loops and all functions immediately when you are attempting to read an item that would be past the eof. Here is a typical set up that will work correctly. Suppose in a data file, there are multiple lines of data. In some function is the loop where you are reading and handling this data. This loop will look similar to the following. // infinite loop to read and handle a line of data for (;;) { $ln = fgets($fp); if (feof($fp)) break; // read the rest of the line // do whatever with data } If you dislike infinite loops, you can accomplish this same thing using a while loop by priming the loop and reading again at the end: $ln = fgets($fp); while (!feof($fp)) { // read the rest of the line // do whatever with data $ln = fgets($fp); } ---- Server IP: 72.52.91.14 Probable Submitter: 173.167.120.17 ---- Manual Page -- http://php.net/manual/en/function.feof.php Edit -- https://master.php.net/note/edit/117578 Del: integrated -- https://master.php.net/note/delete/117578/integrated Del: useless -- https://master.php.net/note/delete/117578/useless Del: bad code -- https://master.php.net/note/delete/117578/bad+code Del: spam -- https://master.php.net/note/delete/117578/spam Del: non-english -- https://master.php.net/note/delete/117578/non-english Del: in docs -- https://master.php.net/note/delete/117578/in+docs Del: other reasons-- https://master.php.net/note/delete/117578 Reject -- https://master.php.net/note/reject/117578 Search -- https://master.php.net/manage/user-notes.php
