Bug #81482 [NEW]: parse_ini_string behaves differently than on PHP 8.0-

From: dseguy at exakat dot io Operating system: PHP version: 8.1.0RC2 Package: Filesystem function related Bug Type: Bug Bug description:parse_ini_string behaves differently than on PHP 8.0- Description: ------------ Here is a simple string that yields an error on PHP 8.1 and nothing on PHP 8.0. https://3v4l.org/Jg3Wu I think the INI code should actually yield an error (the 4th " is actually not escaped) but it used to be processed without error in PHP 8.0 and older. I could not find a mention of parse_ini_* update in the NEWS, so it might be collateral. I suggest a mention of update in the migration manual will be good. Test script: --------------- <?php $ini = <<<'INI' code=" \"\\" value=\\"\" . htmlspecialchars($Value) . \"\\" />\n\"; "; INI; print_r(parse_ini_string($ini)); Expected result: ---------------- Array ( [code] => "\" value=\"" . htmlspecialchars($Value) . "\" />\n"; ) Actual result: -------------- code=" \"\\" value=\\"\" . htmlspecialchars($Value) . \"\\" />\n\"; ";PHP Warning: syntax error, unexpected '=' in Unknown on line 2 -- Edit bug report at https://bugs.php.net/bug.php?id=81482&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=81482&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=81482&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=81482&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=81482&r=needscript Try newer version: https://bugs.php.net/fix.php?id=81482&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=81482&r=support Expected behavior: https://bugs.php.net/fix.php?id=81482&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=81482&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=81482&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=81482&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=81482&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=81482&r=dst IIS Stability: https://bugs.php.net/fix.php?id=81482&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=81482&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=81482&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=81482&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=81482&r=mysqlcfg
