Exceptions

zval * zend_throw_exception(zend_class_entry *exception_ce,
 char *message, long code TSRMLS_DC);
zval * zend_throw_exception_ex(zend_class_entry *exception_ce,
 long code TSRMLS_DC, char *format, ...);
zval * zend_throw_error_exception(zend_class_entry *exception_ce,
 char *message, long code, int severity TSRMLS_DC);
void zend_throw_exception_object(zval *exception_obj TSRMLS_DC);

Throws an exception similar to calling using the throw keyword from userspace. Calling this function from internals does not immediately resume script execution at the next catch block, meaning that additional post-throw processing might be done. After your internal function returns control to the executor however, the catch will be processed.

Argument

exception_obj

A prepared exception object descended from the Exception class.

Numeric exception code; returned by $e->getCode();.

severity

Simple NULL-terminated message.

format

sprintf-style format argument used with subsequent variable argument list.

...

Variable argument list containing data corresponding to the sprintf style format specifier.

zend_class_entry *zend_exception_get_default(void);
zend_class_entry *zend_get_error_exception(void);
