how to insert video to an xampp database php my admin

You need to have a table to insert the video into; Something like this

CREATE TABLE VIDEOTABLE ( ID INTEGER NOT NULL PRIMARY KEY, VIDEONAME VARCHAR (64), VIDEO LONGBLOB );

would give you a table like this:

Row | ID | VIDEONAME | VIDEO |

1 | 33 | My Movie | 10100101...* |

(*I don't actually know how the video-data would be represented in the VIDEO row.)

Once you've created that table, you'd need to insert the movie into it - let's say you have your video saved on your PC at C:\users\example\video\MyMovie.mp4

INSERT INTO VIDEOTABLE VALUES (33, "My Movie", LOAD_FILE("C:\\users\\example\\video\\MyMovie.mp4"));
