What Is Fatal Error In Php

Join them; it only takes php set_error_handler a minute: Sign up PHP try/catch and fatal error up vote 9 down vote favorite 1 I'm using the following script to use a database using PHP: try{ $db = new PDO('mysql:host='.$host.';port='.$port.';dbname='.$db, $user, $pass, $options); } catch(Exception $e){ $GLOBALS['errors'][] = $e; } Now, I want to use this database handle to do a request using this code: try{ $query = $db->prepare("INSERT INTO fatal error in php means users (...) VALUES (...);"); $query->execute(array( '...' => $..., '...' => $... )); } catch(Exception $e){ $GLOBALS['errors'][] = $e; } Here is the problem: When the connection to the DB is OK, everything works, When the connection fails but I don't use the DB, I have the $GLOBALS['errors'][] array and the script is still running afterwards, When the connection to the DB has failed, I get the following fatal error: Notice: Undefined variable: db in C:\xampp\htdocs[...]\test.php on line 32 Fatal error: Call to a member function prepare() on a non-object in C:\xampp\htdocs[...]\test.php on line 32 Note: Line 32 is the $query = $db->prepare(...) instruction. That is to say, the script crashes, and the try/catch seems to be useless. Do you know why this second try/catch don't works and how to solve it? Thanks for the help! EDIT: There are some really good replies. I've validated one which is not exactly what I wanted to do, but which is probably the best approach. php try-catch fatal-error share|improve this question edited Oct 17 '12 at 7:04 asked Oct 17 '12 at 6:35 Ploppe 61117

Una excepción puede ser lanzada ("thrown"), y atrapada ("catched") dentro de PHP. El código puede estar dentro de un bloque try para facilitar la captura de excepciones potenciales. Cada bloque try debe tener al menos un bloque catch o finally correspondiente. El objeto lanzado debe ser una instancia de la clase Exception o una subclase de Exception. Intentar lanzar un objeto que no lo sea resultará en un Error Fatal de PHP. catch Se pueden usar múltiples bloques catch para atrapar diferentes clases de excepciones.

handler set by set_error_handler() and would simply halt script execution. In PHP 7, an exception will be thrown when a fatal and recoverable error (E_ERROR and E_RECOVERABLE_ERROR) occurs, rather than halting script execution. Fatal errors still exist for certain conditions, such as running out of memory, and still behave as before by immediately halting script execution. An uncaught exception will also continue to be a fatal error in PHP 7. This means if an exception thrown from an error that was fatal in PHP 5.x goes uncaught, it will still be a fatal error in PHP 7. Note that other types of errors such as warnings and notices remain unchanged in PHP 7. Only fatal and recoverable errors throw exceptions. Exceptions thrown from fatal and recoverable errors do not extend Exception. This separation was made to prevent existing PHP 5.x code from catching exceptions thrown from errors that used to halt script execution. Exceptions thrown from fatal and recoverable errors are instances of a new and separate exception class: Error. Like any other exception, Error may be caught and handled and will allow any finally blocks to be executed. Prior to PHP 7 alpha-2, the exception hierarchy in PHP 7 was different. Fatal and recoverable errors threw instances of EngineException, which did not inherit from Exception. Both Exception and EngineException inherited from BaseException. The hierarchy was revised with the RFC I authored, Throwable Interface. I felt switching to Throwable and Error was important to avoid confusion from classes using the suffix Exception that did not extend Exception, as well as being more concise and appealing names. Throwable To unite the two exception branches, Exception and Error both implement a new interface, Throwable. The new exception hierarchy in PHP 7 is as follows: interface Throwable |- Exception implements Throwable |- ... |- Error implements Throwable |- TypeError extends Error |- ParseError extends Error |- ArithmeticError extends Error |- DivisionByZeroError extends ArithmeticError |- AssertionError extends Error PHP 7 exception hierarchy If Throwable was defined in PHP 7 code, it would look like the code below. interface Throwable { public function get
