Edit report at https://bugs.php.net/bug.php?id=71994&edit=1 ID: 71994 Updated by: pollita@php.net Reported by: temp at temp dot ru Summary: Octal escape sequences are not checked for overflow -Status: Assigned +Status: Closed Type: Bug Package: Scripting Engine problem Operating System: Any PHP Version: Irrelevant Assigned To: pollita Block user comment: N Private report: N New Comment: Agreed course of action is that as of PHP 7.1 we'll raise a compile time warning, but continue to allow the value to overflow. At a later time, this may be promoted to a full error, but for now we're keeping BC.

Test script: --------------- <?php echo ord("\777"[0]) . PHP_EOL; echo ord("\666"[0]) . PHP_EOL; echo ord("\555"[0]) . PHP_EOL; Expected result: ---------------- Some kind of error, because all of \777, \666, \555 sequences are invalid, their value is greater than 255. Actual result: -------------- 255 182 109 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71994&edit=1
