new to php

And there are indeed such flaws in MySQL, imho. Think of this - there are certain types of SQL tables (heap?) that are stored in RAM, not on the HD. These could theoretically be inserted to until your memory is filled and your computer slows down with massive amounts of swapping

this is not really about php but an html question. i am using a table to output the links on the top of my site and the text is to small and i was wondering how i could change the size of the links text.

That's unideal though. Since is a deprecated tag, it's better to use CSS. In your stylesheet, add:

.smallfont { font-size: 0.75em; }
.regfont { font-size: 1.00em; }
.bigfont { font-size: 1.25em;}
.hugefont {font-size: 1.67em; }

Then in your html, just use:

Here's some big text! 
But this is tiny.

is there any real difference between the echo(); and print(); commands

I don't really use print, and I don't know anyone who does. print_r is sometimes useful.

No real difference. echo 'stuff'; has been shown to be the fastest of the various types of echo and print, though.

Here's a good explanation of why echo is slightly faster:

in php are variables global and if i make a connection to mysql or start a session do i have to start one on each seperate page or only on one page.

Variables carry the same scope as with C and C++. Variables are local within functions, but you can globalize with the command: global $variable in any function.

true, you have to either store vars in a session/cookie, get/post var, a text file, or a database.
