ID: 26662 Updated by: alindeman@php.net Reported By: alindeman@php.net -Status: Bogus +Status: Open Bug Type: Scripting Engine problem Operating System: Linux PHP Version: 4CVS-2003-12-18 (stable) New Comment: This is not a dup, as it is not fixed in PHP 5. Re-opening. Previous Comments: ------------------------------------------------------------------------ [2003-12-18 21:42:28] iliaa@php.net Please do not submit the same bug more than once. An existing bug report already describes this very problem. Even if you feel that your issue is somewhat different, the resolution is likely to be the same. Thank you for your interest in PHP. Dupe of bug #26601 which is marked won't fix. ------------------------------------------------------------------------ [2003-12-18 21:29:16] davey@php.net Verified on PHP5b2, FreeBSD 4.4. PHP4 Snapshot on FreeBSD 4.4 yields this: [davey@omestre:~/php4-STABLE-200312190030/sapi/cli]$ ./php -r '${1} = "foo"; echo ${1}, "\n";' Segmentation fault (core dumped) Running the script on Win32 PHP4 snapshot (same one) gives an "Application Error". ------------------------------------------------------------------------ [2003-12-18 21:25:21] john@php.net Confirmed this bug is in PHP 5 B3RC1 as well. It gets worse, you can put whatever you want in ${} and it'll take it just fine... ------------------------------------------------------------------------ [2003-12-18 21:06:52] alindeman@php.net Description: ------------ It is possible to set variables that start with numbers. I reproduced this with a PHP 4.3.x-dev snapshot AND PHP 5.0.0b2 (I was unable to get a snap to compile. autoconf errors out the wazoo). Reproduce code: --------------- andrew@laptop cli $ ./php -r '${1} = "foo"; echo ${1}, "\n";' foo Expected result: ---------------- A parse error Actual result: -------------- Outputs 'foo' ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26662&edit=1
