Req #67860 [Opn]: Throw an "acceptable" exception

Edit report at https://bugs.php.net/bug.php?id=67860&edit=1 ID: 67860 User updated by: david dot proweb at gmail dot com Reported by: david dot proweb at gmail dot com Summary: Throw an "acceptable" exception Status: Open Type: Feature/Change Request Package: *General Issues Operating System: Irrelevant PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Actually it would make errors in a casual exception, so that I could capture it in a more reliable manner. $variable = [1, 2, 3]; echo $variable; // Notice: Array to string conversion. How I can capture that? (In this case, I could avoid it by checking if the variable is compatible, but it is only an example.) With the feature, I could do: try { echo $variable; } catch(Exception $e) { if(strpos($e->getMessage(), "Array to string conversion")) { echo "Check option user_type, it accept only string."; } } Previous Comments: ------------------------------------------------------------------------ [2014-08-19 01:49:21] requinix@php.net If you don't want to deal with exceptions then don't use them in your code. ------------------------------------------------------------------------ [2014-08-19 01:13:31] david dot proweb at gmail dot com Description: ------------ Imagine that you do ($a / $b), but $b is zero. So you will receives "Warning: Division by zero.". You can avoid that by doing @($a / $b), something like that. But imagine if PHP can thrown an exception that not need be captured. It is: you can, optionally, capture that, but if not, will only thrown a notice, instead of warning. // Supposing that it is the PHP division constructor: function php_div($a, $b) { if($b === 0) { throw casual new Exception("Division by zero."); } return $a / $b; } // So if I do: 5 / 0; // Notice: Division by zero. // But I can do: try { 5 / 0; } catch(Exception $e) { ... } // Avoid notice. // Or even: @(5 / 0); // Avoid casual Exception. -- User can throw casual exceptions too. For instance: function name_fix($name) { ... if(name_uncommon($name)) { throw casual new Exception("This name is uncommon."); } ... return $name_fixed; } echo name_fix("David"); // David echo name_fix("Hakuna Matata"); // Hakuna Matata + Notice // When you capture that, statement will be blocked. try { echo name_fix("Hakuna Matata"); } catch(Exception $e) { echo "The Hakuna Matata is so uncommon."; } // -> The Hakuna Matata is so uncommon. (not echo name, not notice) -- Exception need a new property like boolean $isCasual ($e->isCasual()). -- Note: apply it to "division by zero" is only to examplify my feature request. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67860&edit=1
