mysql - How to delete two rows together with foreign key relationship -


i have 2 tables , these 2 have relationship like

class lesson { /**  * @var integer  *  * @orm\column(name="id", type="integer")  * @orm\id  * @orm\generatedvalue(strategy="auto")  */ private $id;    class ticketuse   { /**  *  * @orm\manytoone(targetentity="acme\userbundle\entity\lesson")  * @orm\joincolumn(name="lessonid", referencedcolumnname="id")  */  private $lessonid;

these 2 tables relation ships are.

if row in lesson exist,a row in ticketuse exists or doesn't exist.

if row in ticketuse exists has combination row in lesson.

when try delete lesson row 'delete lesson id = 1'

it shows error.

sqlstate[23000]: integrity constraint violation: 1451 cannot delete or update parent row: foreign key constraint fails

i want delete ticketuse automatically,when delete lesson.

is there way delete both together?

i have 2 write delete sentences each?

for foreign key relationship, add on update cascade.
able delete according needs.
when delete parent change automatically reflected child.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/...
