#28926 [NEW]: feof() problems if 2 files are open

From: jochen at keutel dot de Operating system: Solaris 8 PHP version: 4.3.7 PHP Bug Type: Filesystem function related Bug description: feof() problems if 2 files are open Description: ------------ If I open 2 files with fopen and parse them with fgets then feof doesn't work correctly. Example: file1: (2 lines) line 1 line 2 file2: (4 lines) line 1 line 2 line 3 line 4 The code provided should return only 2 lines of file1 and should stop than. but it returns 3 lines of file1. If I remove the code handling file2 from the code (http://keutel.de/test_feof2.txt) then all works fine. Reproduce code: --------------- see http://keutel.de/test_feof1.txt : $handle1 = fopen ("file1", "r"); $handle2 = fopen ("file2", "r"); while (TRUE) { if (feof($handle1) && feof($handle2)) { echo "both over\n"; break; } if (feof($handle1) || feof($handle2)) { echo "one is over\n"; break; } $buffer1 = fgets($handle1, 4096); $buffer2 = fgets($handle2, 4096); echo "file1: ".$buffer1; echo "file2: ".$buffer2; } Expected result: ---------------- file1: line 1 file2: line 1 file1: line 2 file2: line 2 one is over Actual result: -------------- file1: line 1 file2: line 1 file1: line 2 file2: line 2 file1: file2: line 3 one is over -- Edit bug report at http://bugs.php.net/?id=28926&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28926&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28926&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28926&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28926&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28926&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28926&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28926&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28926&r=support Expected behavior: http://bugs.php.net/fix.php?id=28926&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28926&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28926&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28926&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28926&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28926&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28926&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28926&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28926&r=float
