How can I replace specific fields of an existing row in php+mysql ?

Table
Field1 Field2 Field3
value1 value2 value3

You could just do a simple UPDATE statement.

UPDATE Table SET Field3 = 'NewValue' WHERE Field1 = 'value1'

the sql query is like (using UPDATE) :

UPDATE Table SET Field3 = 'mynewvalue' where Field1 = 'Value1'

to run it in php use

mysql_query or mysqli::query()
