(PHP MySQL) DELETE FROM

The DELETE FROM statement is used to delete rows from a database table. The following example creates and populates a Members table using the following SQL commands: 

CREATE TABLE Members (
  ID   INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(16) NOT NULL );
   
INSERT INTO Members( name ) VALUES( '$name1' );

and deletes the items using: 

DELETE FROM Members WHERE name LIKE '%$name2%';
