Currently the new site is going to be using a MySQL back end, php middle-ground and apache serving up the pages.
I have found a multitude of very reliable, very helpful PHP/MySQL tutorials. The problem is that every tutorial uses the mysql_* functions. This is fine right now, but it's entirely possible that I might switch to postgresql/MSSQL/etc some time in the not-too-distant future if I have to change my hosting company.
I can write my own wrappers without too much difficulty (I think)... but is there a built-in or pre-rolled perl-like DBI for php? Not like as in syntactically, but like as in universal regardless of database?
