Errors in PHP 7
Errors in PHP 7
PHP 7 changes how most errors are reported by PHP. Instead of reporting
errors through the traditional error reporting mechanism used by PHP 5, most
errors are now reported by throwing exceptions.
Error
As with normal exceptions, these exceptions will bubble up until they reach the first matching
block. If there are no matching blocks, then any default exception handler
installed with will be called,
and if there is no default exception handler, then the exception will be
converted to a fatal error and will be handled like a traditional error.
Errorcatchset_exception_handler
As the hierarchy does not inherit from
, code that uses
blocks to handle uncaught
exceptions in PHP 5 will find that these s are
not caught by these blocks. Either a
block or a handler is required.
