Update Data In a Database

The UPDATE statement is used to modify data in a database table.

Syntax

UPDATE table_name
SET column_name = new_value
WHERE column_name = some_value welcome to phpsu.com 

To get PHP to execute the statement above we must use the mysql_query() function. This function is used to send a query or command to a MySQL connection.

Example
