Previous Comments: ------------------------------------------------------------------------ [2002-07-01 15:10:48] sander@php.net Can't reproduce with the latest CVS. Can you try a snapshot from http://snaps.php.net to see if it's been fixed? ------------------------------------------------------------------------ [2002-03-13 17:29:53] pjm@cctechnol.com I also tested this on Red Hat 7.2 with PHP 4.0.6 It works fine there. ------------------------------------------------------------------------ [2002-03-13 17:00:20] pjm@cctechnol.com The fgets() function works differently when the input is a pipe. Specifically, feof() returns true after the first line is read. The test script and sample output follow. The test script works fine if stdin is redirected from a file. It fails if stdin is a pipe. Nothing special about the build: ./configure --prefix=/usr/local --with-mysql pjm@poseidon> cat test.php #!/usr/local/bin/php -q <?php $fd = fopen("php://stdin", "r"); while (! feof($fd)) { $buffer = fgets($fd, 4096); echo $buffer; } ?> pjm@poseidon> < test.php ./test.php #!/usr/local/bin/php -q <?php $fd = fopen("php://stdin", "r"); while (! feof($fd)) { $buffer = fgets($fd, 4096); echo $buffer; } ?> pjm@poseidon> cat test.php | ./test.php #!/usr/local/bin/php -q ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16048&edit=1
