Bug #81454 [NEW]: error_reporting() and ini_get('error_reporting') can get out of sync using @

From: daimona dot wiki at gmail dot com Operating system: Any PHP version: Irrelevant Package: Scripting Engine problem Bug Type: Bug Bug description:error_reporting() and ini_get('error_reporting') can get out of sync using @ Description: ------------ This bug is a direct consequence of bug #75924. That one essentially states that, starting with PHP 7, the @ operator affects the output of error_reporting(), but not that of ini_get('error_reporting'). Now, consider the following test case: https://3v4l.org/70QJY For the PHP 7 examples, I'd expect error_reporting() and ini_get() to return the same value (-1) in "POST", but this is not the case. AIUI, it happens because: - error_reporting() and ini_get() are out of sync when testFunc() starts, per bug #75924 - error_reporting(0) syncs them again, as expected - Same for error_reporting($orig) - But then, when the silenced statement ends, only error_reporting() is restored (because only error_reporting() was changed by @, I guess) This bug affects all versions of PHP starting from 7.0. PHP 8 is also affected, even though some numeric values are different. Test script: --------------- function testFunc() { print "INSIDE 1 er=" . error_reporting() . ' ini=' . intval( ini_get( 'error_reporting' ) ) . "\n"; $orig = error_reporting( 0 ); print "INSIDE 2 er=" . error_reporting() . ' ini=' . intval( ini_get( 'error_reporting' ) ) . "\n"; error_reporting( $orig ); print "INSIDE 3 er=" . error_reporting() . ' ini=' . intval( ini_get( 'error_reporting' ) ) . "\n"; } print "PRE er=" . error_reporting() . ' ini=' . intval( ini_get( 'error_reporting' ) ) . "\n"; @testFunc(); print "POST er=" . error_reporting() . ' ini=' . intval( ini_get( 'error_reporting' ) ) . "\n"; Expected result: ---------------- PRE er=-1 ini=-1 INSIDE 1 er=0 ini=0 INSIDE 2 er=0 ini=0 INSIDE 3 er=0 ini=0 POST er=-1 ini=-1 Actual result: -------------- PRE er=-1 ini=-1 INSIDE 1 er=0 ini=-1 INSIDE 2 er=0 ini=0 INSIDE 3 er=0 ini=0 POST er=-1 ini=0 -- Edit bug report at https://bugs.php.net/bug.php?id=81454&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=81454&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=81454&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=81454&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=81454&r=needscript Try newer version: https://bugs.php.net/fix.php?id=81454&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=81454&r=support Expected behavior: https://bugs.php.net/fix.php?id=81454&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=81454&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=81454&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=81454&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=81454&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=81454&r=dst IIS Stability: https://bugs.php.net/fix.php?id=81454&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=81454&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=81454&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=81454&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=81454&r=mysqlcfg
