Bug #71240 [NEW]: array_filter byref value in callable no longer working

From: donatj at gmail dot com Operating system: PHP version: 7.0.1 Package: *General Issues Bug Type: Bug Bug description:array_filter byref value in callable no longer working Description: ------------ It would appear that passing by reference in the callable of array_filter no longer functions as expected. I can find no documentation of this change on the array_filter page. The expected result is seen in 5.3 -> 5.6 Test script: --------------- <?php $files = array('AAA', 'BBB', 'CcC'); $files = array_filter($files, function ( &$path ) { $path = strtolower($path); return true; }); print_r($files); Expected result: ---------------- Array ( [0] => aaa [1] => bbb [2] => ccc ) Actual result: -------------- Array ( [0] => AAA [1] => BBB [2] => CcC ) -- Edit bug report at https://bugs.php.net/bug.php?id=71240&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71240&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71240&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71240&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71240&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71240&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71240&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71240&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71240&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71240&r=support Expected behavior: https://bugs.php.net/fix.php?id=71240&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71240&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71240&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71240&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71240&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71240&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71240&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71240&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71240&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71240&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71240&r=mysqlcfg
