note 68005 added to language.exceptions

Carlos Konstanski: You can't directly extract previous lexical environment in non-functional languages. What you probably _can_ do is to create a function that dumps the current lexical environment (to an external file or to stdout) and then use it to recreate past states. function log_lex ($vars, $functions) { $f = fopen('lex_env.log', 'a'); fwrite($f, serialize(array($vars, $functions, get_defined_constants(), debug_backtrace())); fclose($f); } log_lex (get_defined_vars(), get_defined_functions()); Writing the parser/browser for dumps is the difficult part. Then just sprinkle the code with log_lex() and see how the program runs. Sure, it works better in Lisp, but Lisp isn't supported on the webservers I work with, and making PHP more like Lisp would probably make it as popular as Lisp is. ---- Server IP: 83.64.128.68 Probable Submitter: 87.206.201.94 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/language.exceptions.php Edit -- http://master.php.net/note/edit/68005 Del: integrated -- http://master.php.net/note/delete/68005/integrated Del: useless -- http://master.php.net/note/delete/68005/useless Del: bad code -- http://master.php.net/note/delete/68005/bad+code Del: spam -- http://master.php.net/note/delete/68005/spam Del: non-english -- http://master.php.net/note/delete/68005/non-english Del: in docs -- http://master.php.net/note/delete/68005/in+docs Del: other reasons-- http://master.php.net/note/delete/68005 Reject -- http://master.php.net/note/reject/68005 Search -- http://master.php.net/manage/user-notes.php
