My linux distro already came with apache and php installed, but for some reason they were not configured to work together. After hours of trying to get this to work I am giving up. So I searched on the net and found an all-in-one installation for apache-php-mysql that will work right out of the box. The problem is, the download size is too big (i'm on dialup) because it also includes a whole bunch of things I don't need like openssl and perl. Does anyone know of any all-in-one apache-php-mysql installations for linux that include nothing other than php/apache/mysql so that the download size is small? I've already found one for windows but would prefer to work in linux. Thanks in advance!

All it takes in Slackware to enable Apache and php to work together is uncommenting near the end of httpd.conf and make sure your <IfModule mod_dir.c> has index.php at the end.
But to answer your question, no, I don't know of any "small enough for dialup" all in one lamp packages. Perhaps no one expected someone on dialup to host a lamp server.
