Dad Joeller won't help me

I have a philosophical PHP question: Why would I do, "a" instead of, "b"???
a.)
<?php
ob_start();
$start = microtime();
//do benchmarktest here
$end = microtime();
ob_end_clean();
echo "it took " . ($end-$start) . " seconds";
?>

b.)
<?php
$start = microtime();
//do benchmarktest here
$end = microtime();
echo "it took " . ($end-$start) . " seconds";
?>

So, Why make a "function" out of it? Why do PHP books always give examples where functions are made?

function are made to be reusable and if you code with this concept then code will be easire inthe future if you have a collection of reusable function so to stay in the habbit it is better to use and code in a function good pratice

So, for example, how would I, "reuse" that code? The first line of my "function" started with, "ob_start();"

So, does that mean that if I wish to reuse it later, I just type <?php ob_start(); ?> and that's it?

I don't think so. I have to type all 6 lines of code whenever I want to use it:
<?php
ob_start();
$start = microtime();
//do benchmarktest here
$end = microtime();
ob_end_clean();
echo "it took " . ($end-$start) . " seconds";
?>

So, I just don't get the idea of, "reuseability." Or, am I wrong?

"a" is not a function! A function is defined using the keyword "function", e.g.

function benchmark() {
ob_start();
// etc..
ob_end_clean();
}

That will make a function, but your code in "a" does not make a function, so your question does not make sense...

Again You can have a file called function.inc
were you will store you functions
when you want to use these function you would do something like this

include('functions.inc');

assuming you all ready define this function in your function.inc file

ob_start();

this will run the function

Take look a the php manuel to get more ideas
