Req #80202 [NEW]: request "y" and "n" support for FILTER_VALIDATE_BOOLEAN

From: divinity76 at gmail dot com Operating system: PHP version: Next Minor Version Package: Unknown/Other Function Bug Type: Feature/Change Request Bug description:request "y" and "n" support for FILTER_VALIDATE_BOOLEAN Description: ------------ i wish for FILTER_VALIDATE_BOOLEAN to support "y" (for bool(true)) and "n" (for bool(false)) in shell scripts, "y" and "n" often mean "yes" and "no" for yes/no questions in shell scripts, as an example, the GNU Coreutils "yes" program (usually located at /usr/bin/yes , https://man7.org/linux/man-pages/man1/yes.1.html ) will spam "y\n" indefinitely, to be used in shell scripts that ask for yes/no questions, for example "yes | sensors-detect" to tell lm-sensors' sensors-detect to scan for all supported sensors, so when writing php shell scripts asking for yes/no, it's a shame that FILTER_VALIDATE_BOOLEAN doesn't support y/n, now one has to write something like <?php $confirm = readline("confirm: "); $confirm = ((strtolower($confirm)) === "y" ? true : ((strtolower($confirm)) === "n" ? false : (filter_var($confirm, FILTER_VALIDATE_BOOLEAN, FILTER_NULL_ON_FAILURE)))); if($confirm === null){ "error didn't understand blah blah"; } ?> instead of <?php $confirm = readline("confirm: "); $confirm = filter_var($confirm, FILTER_VALIDATE_BOOLEAN, FILTER_NULL_ON_FAILURE); if($confirm === null){ "error didn't understand blah blah"; } ?> Test script: --------------- <?php var_dump( filter_var('y', FILTER_VALIDATE_BOOLEAN, FILTER_NULL_ON_FAILURE), filter_var('n', FILTER_VALIDATE_BOOLEAN, FILTER_NULL_ON_FAILURE) ); Expected result: ---------------- bool(true) bool(false) Actual result: -------------- NULL NULL -- Edit bug report at https://bugs.php.net/bug.php?id=80202&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=80202&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=80202&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=80202&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=80202&r=needscript Try newer version: https://bugs.php.net/fix.php?id=80202&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=80202&r=support Expected behavior: https://bugs.php.net/fix.php?id=80202&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=80202&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=80202&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=80202&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=80202&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=80202&r=dst IIS Stability: https://bugs.php.net/fix.php?id=80202&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=80202&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=80202&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=80202&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=80202&r=mysqlcfg
