Throwing Exceptions

When you throw an exception using the Phalcon API, the current flow of execution will be stopped, returning to the last PHP code block when a Phalcon method where called.

There are two ways to throw exceptions, the first, when the exception object only receives a string as parameter:

PHALCON_THROW_EXCEPTION_STR(phalcon_exception_ce, "Hey this is an exception");

Or building the exception manually and then throwing it:

PHALCON_INIT_VAR(exception_message);
PHALCON_CONCAT_SVS(exception_message, "Unable to insert into ", table, " without data");

PHALCON_INIT_VAR(exception);
object_init_ex(exception, phalcon_db_exception_ce);

//The exception constructor must be manually called
PHALCON_CALL_METHOD_PARAMS_1_NORETURN(exception, "__construct", exception_message, PH_CHECK);
phalcon_throw_exception(exception TSRMLS_CC);
return;
