ID: 77224 Updated by: ni...@php.net Reported by: fkruidhof at mailbox dot org Summary: Stack Trace shows wrong parameter value Status: Open Type: Bug Package: Testing related Operating System: MacOs Mojave PHP Version: 7.2.12 Block user comment: N Private report: N New Comment: This is one of the unfortunate changes resulting from optimizations in PHP 7. It's noted in the PHP 7 migration guide here: https://secure.php.net/manual/en/migration70.incompatible.php#migration70.incompatible.other.func-parameter-modified It's a known issue, but as far as I'm aware there is no work towards improving this (if it can be improved). Previous Comments: ------------------------------------------------------------------------ [2018-11-30 09:45:51] fkruidhof at mailbox dot org Description: ------------ The stack trace from an exception shows the wrong value of the parameter that was passed to a function if it's value is changed inside that function (before the exception is thrown). First bug report, novice PHP developer. Apologies if I miscategorized this report. Test script: --------------- <?php $variable = 'foo'; one($variable); function one($variable) { try { two($variable); } catch (Exception $e) { echo $e->getTraceAsString(); } } function two($variable) { $variable = 'bar'; throw new Exception('problem'); } Expected result: ---------------- Stack trace output: #0 /file.php(8): two('foo') #1 /file.php(3): one('foo') #2 {main} Actual result: -------------- Stack trace output: #0 /file.php(8): two('bar') #1 /file.php(3): one('foo') #2 {main} ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77224&edit=1
