Excecute a string command

[Anon]

Hello,

I create a string with a command in it, because it's variable. Is it possible to excecute that string.

function query( $sql, $op )
{
$exe = "\$this->" . $this->dbType . "query( )";
}

function mysql_query( $sql, $op )
{
...
}

function mssql_query( $sql, $op )
{
...
}

Theoretically yes, but this will create one huge mess.

Do you really have to be able to run on both databases at the same time?

Technically, yes, you can. Look at the page here:

http://www.php.net/exec

But using this (especially in conjunction with user supplied data) you can end up creating very large security holes. There are MANY better ways to handle database abstraction. I suggest looking at PEAR (it comes with your php distribution) they have a very nice database abstraction class for pretty much any database you could want. You can reach the site for pear at:

http://pear.php.net/

Hope that helps!
