RE: [PHP] Try{} Catch()

use it just like in JAVA, It offers a uniform/good way to manage exception in app. e.g. function getObjFromDB($key) { if (strlen($key)!=0 ) throw new Exception ("need condition ."); if (!mysql_connect(...)) throw new Exception ("can't connect to db ."); ..... } function foo () { $err=''; for (...) { try { getObjFromDB(''); } catch (Exception $e) // if you throw a exception but didn't catch it , the PHP app will stop and not prompt any error message. { echo $e; //output the error message. $err .= $e; } } echo "done , total message : {$err}"; } > -----Original Message----- > From: Al [mailto:news@ridersite.org] > Sent: Monday, December 24, 2007 5:59 AM > To: php-general@lists.php.net > Subject: Re: [PHP] Try{} Catch() > > I understand it's intended use and how to use it, have just > not found a good use for it yet. > > > > Martin Alterisio wrote: > > It's not supposed to be practical, it's just a way to > handle errors.
