?>MySQL DELETE
To delete data from a table, you use the MySQL DELETE statement. The following illustrates the syntax of the DELETE statement:
DELETE FROM table_name
WHERE condition;
In this statement:
First, specify the table from which you delete data.
Second, use a condition to specify which rows to delete in the WHERE clause. The DELETE statement will delete rows that match the condition,php delete
