1.2.1249. Undefined Caught Exceptions

Those are exceptions that are caught in the code, but are not defined in the application.

They may be externally defined, such as in core PHP, extensions or libraries. Make sure those exceptions are useful to your application : otherwise, they are dead code.

<?php

try {
    library_function($some, $args);

} catch (LibraryException $e) {
    // This exception is not defined, and probably belongs to Library
    print "Library failed\n";

} catch (OtherLibraryException $e) {
    // This exception is not defined, and probably do not belongs to this code
    print "Library failed\n";

} catch (\Exception $e) {
    // This exception is a PHP standard exception
    print "Something went wrong, but not at Libary level\n";
}

?>
