note 124019 added to language.exceptions

This page states, "Code may be surrounded in a try block, to facilitate the catching of potential exceptions." There are two ways in which code may be "surrounded". The obvious (intuitive) way is lexical enclosure: all the code to be protected by the try block is surrounded like this: try { A(); function A() { throw new Exception('error'); echo "A()"; } // A } // try catch... The other way to enclose is by execution (dynamic enclosure), like this: try { A(); } // try catch... function A() { throw new Exception('error'); echo "A()"; } // A The sense in which code is "surrounded" for exception handling is dynamic (the second example above). This is because exception handling is dynamic and works by "unwinding" the execution stack. ---- Server IP: 208.43.231.9 Probable Submitter: 82.199.157.34 (proxied: 98.2.238.89) ---- Manual Page -- http://php.net/manual/en/language.exceptions.php Edit -- https://master.php.net/note/edit/124019 Del: integrated -- https://master.php.net/note/delete/124019/integrated Del: useless -- https://master.php.net/note/delete/124019/useless Del: bad code -- https://master.php.net/note/delete/124019/bad+code Del: spam -- https://master.php.net/note/delete/124019/spam Del: non-english -- https://master.php.net/note/delete/124019/non-english Del: in docs -- https://master.php.net/note/delete/124019/in+docs Del: other reasons-- https://master.php.net/note/delete/124019 Reject -- https://master.php.net/note/reject/124019 Search -- https://master.php.net/manage/user-notes.php
