This is same issue. One report per problem. Previous Comments: ------------------------------------------------------------------------ [2008-02-22 17:58:34] exe at travian dot org Description: ------------ If STDOUT/STDERR are closed by a script then the first two file handles opened by that script afterwards will take the place of the former STDOUT/STDERR handles. This will cause any output which normaly goes to STDOUT (like in print/echo statements) to be written to the new file handles. This behaviour may corrupt files written by that script. This is a similar problem as in bug #44217. Reproduce code: --------------- <?php fclose(STDOUT); fclose(STDERR); $fp1 = fopen('test.log', 'a'); // File handle 1, formerly STDOUT $fp2 = fopen('test.log', 'a'); // File handle 2, formerly STDERR print "foo"; // Will be written to test.log ?> Expected result: ---------------- No output from php, no appended output in test.log Actual result: -------------- String "foo" will be appended to test.log strace shows that php first closes file handle 1 (stdout) and 2 (stderr) and then openes two file handles, which get the numbers 1 and 2, and then print "foo" to file handle 1 which now points to test.log: read(3, "<?php\nfclose(STDOUT); fclose(STD"..., 8192) = 217 read(3, "", 4096) = 0 read(3, "", 8192) = 0 close(3) = 0 munmap(0x2b97a043e000, 4096) = 0 close(1) = 0 munmap(0x2b97a0440000, 4096) = 0 close(2) = 0 getcwd("/root", 4096) = 6 lstat("/root", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 lstat("/root/test.log", {st_mode=S_IFREG|0644, st_size=290, ...}) = 0 open("/root/test.log", O_WRONLY|O_APPEND|O_CREAT, 0666) = 1 fstat(1, {st_mode=S_IFREG|0644, st_size=290, ...}) = 0 lseek(1, 0, SEEK_CUR) = 0 lseek(1, 0, SEEK_CUR) = 0 getcwd("/root", 4096) = 6 open("/root/test.log", O_WRONLY|O_APPEND|O_CREAT, 0666) = 2 fstat(2, {st_mode=S_IFREG|0644, st_size=290, ...}) = 0 lseek(2, 0, SEEK_CUR) = 0 lseek(2, 0, SEEK_CUR) = 0 write(1, "foo", 3) = 3 close(2) = 0 close(1) = 0 close(0) = 0 munmap(0x2b97a043f000, 4096) = 0 munmap(0x2b97a03fd000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2b97a03fd000 setitimer(ITIMER_PROF, {it_interval={0, 0}, it_value={0, 0}}, NULL) = 0 munmap(0x2b97a03fd000, 266240) = 0 brk(0xd36000) = 0xd36000 exit_group(0) = ?
