I'm working with a php application, and there is a line that moves a file. I enclosed the method within a try...catch block so, if a error is thrown, can manage a rollback system. But the exception is never catched, so, renames throws any kind of exception? Do I need to try with another method?
Thanks
Code above:
try{ if(rename($archivo_salida, $ruta_archivos)){ //anything; } }catch (Exception $e) //do something } "Normal" PHP functions don't throw exceptions.
Change your code to simulate an exception:
try { if (rename($archivo_salida, $ruta_archivos)) { //anything; } else { throw new Exception('Can not rename file'.$archivo_salida); } } catch (Exception $e) { //do something, such as echo 'Caught exception: ', $e->getMessage(), "\n"; } 
rename() only ever returns true/false - there is no thrown exception.
It returns FALSE on failure. See http://php.net/manual/en/function.rename.php
If you really need an exception to be thrown when the rename fails, you can do this:
if (rename($archivo_salida, $ruta_archivos)) { // anything; } else { throw new Exception("Rename failed."); } Now, you can wrap this around a try {} catch {} block where ever you are invoking this code.
You can also use the same approach as described in this answer: https://stackoverflow.com/a/43364340/563049
Create a custom exception class and use it's static constructor method with or operator after rename().
Exception class:
class CustomException extends Exception { static public function doThrow($message = "", $code = 0, Exception $previous = null) { throw new Exception($message, $code, $previous); } } Usage:
try { rename($archivo_salida, $ruta_archivos) or CustomException::doThrow('Renaming failed.'); } catch (Exception $e){ //do something } Note
If you are using PHP 7 and higher - you can rename static method
doThrow()to simplythrow(), since in PHP 7 and higher it's allowed to use reserved keywords as method names.
