This is inconsistent with the case where you actually have two lines in a file, and stream_get_line reports two lines as expected without the additional empty third line. This inconsistency makes it quite difficult to write a correct code. Test script: --------------- I have three files: lopuszanski@vanisoft:~$ hexdump -C one_line.txt 00000000 61 0a |a.| 00000002 lopuszanski@vanisoft:~$ hexdump -C two_lines.txt 00000000 61 0a 62 0a |a.b.| 00000004 lopuszanski@vanisoft:~$ hexdump -C two_lines_one_of_which_is_empty.txt 00000000 61 0a 0a |a..| 00000003 And the following script: lopuszanski@vanisoft:~$ cat test.php <?php while(!feof(STDIN)){ $line = stream_get_line(STDIN,1000000,"\n"); var_dump($line); } ?> Expected result: ---------------- lopuszanski@vanisoft:~$ php test.php < one_line.txt string(1) "a" lopuszanski@vanisoft:~$ php test.php < two_lines.txt string(1) "a" string(1) "b" lopuszanski@vanisoft:~$ php test.php < two_lines_one_of_which_is_empty.txt string(1) "a" string(0) "" Actual result: -------------- lopuszanski@vanisoft:~$ php test.php < one_line.txt string(1) "a" string(0) "" lopuszanski@vanisoft:~$ php test.php < two_lines.txt string(1) "a" string(1) "b" lopuszanski@vanisoft:~$ php test.php < two_lines_one_of_which_is_empty.txt string(1) "a" string(0) "" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60455&edit=1
