From: michael dot piche at csrt dot ulaval dot ca Operating system: Windows PHP version: 7.4.2 Package: *Directory/Filesystem functions Bug Type: Bug Bug description:PHP 7.4 error with php://stderr Description: ------------ Since PHP 7.4, the stream php://stderr is giving me a PHP notice "Bad file descriptor".

I've got the same error with php://stdout Test script: --------------- $fp = fopen('php://stderr', 'w+'); var_dump($fp); fwrite($fp, "test\n"); Actual result: -------------- resource(3) of type (stream) Notice: fwrite(): write of 5 bytes failed with errno=9 Bad file descriptor in D:\htdocs\test_code\74.php on line 7 -- Edit bug report at https://bugs.php.net/bug.php?id=79166&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79166&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79166&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79166&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79166&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79166&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79166&r=support Expected behavior: https://bugs.php.net/fix.php?id=79166&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79166&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79166&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79166&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79166&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79166&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79166&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79166&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79166&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79166&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79166&r=mysqlcfg
