Yes, I know I can do it using a while statement, but is there a PHP mysql function to move all the data obtained in a query to an array that can be returned from a user written function in one statement ? bill

The added performance overhead is just one of them. PDO has its uses. But it is not the end-all to everything. That's why there are different ways of doing what is basically the same thing. -- ================== Remove the "x" from my email address Jerry Stuckle JDS Computer Training Corp. jstucklex@attglobal.net ==================

Just consider that any function is using a loop to read the entire result set, whether built-in or user coded. Not gonna make that much of a difference as far as that goes. -- Norman Registered Linux user #461062 -Have you been to www.php.net yet?-

The overhead is minimal due to the fact it is a compiled extension, and the object functions are just gorgeous: each row goes into one object. Together with objects specifically defined for your database tables this makes an easy start into OO. /Str.

I think people only talking about mysql are thinking small. You should not give away flexibility when it comes at small cost. Small cost: the alleged performance of PDO is rather my experience. Additionally the web search turned up in the first hits: http://www.el-bato.de/it/php-mysql-vs-mysqli-vs-pdo-performance (sorry, in german) Before we start discussing benchmarks I would like to know: what especially do you not like about it? /Str.

Flexibility is quite limited. Take a query with a LIMIT clause and try to execute it on a MSSQL server. Or dealing with date data.

You stating "the overhead is minimal due to the fact it is a compiled extension". Just being a compiled extension doesn't say anything about performance penalties (or lack thereof). Gregor
