Hello Ophir, thanks for the reply.
Its really basic stuff. A Flash file will send via POST to a PHP
script some text. I need to insert the text in MySQL in a row which
have an auto_increment column. I want to keep only the last 10 text,
so I will query MySQL to get all the text, and if I have more than 10
texts, I will delete the older ones.
