Problem posting more than 5000 chars in a MS SQL database using PHP 4

Hi, I have a problem using PHP 4 and MS SQL 7. I made a site management system by putting all the HTML pages in a table and use a webinterface to edit the pages. When I try to put HTML pages in the database, it does everything like normal (gives me no error). But when refresh my screen, the bottom of the page seems to be lost. The datatype in the database is text, so it should be large enough to store a whole HTML page (like 10000 chars). When I edit the page, I'm using a normal HTML text field and post the value to the same script (where it becomes a string). I don't know where the data is lost. Can somebody help me?
