You will still get the benchmark of the functions, you just declare them
outside of your benchmarking loop so they don't get re-declared.
Pardon my syntax, I'm just going to try to demonstrate (using the
"getmicrotime" function from the PHP manual):
<?php
Function dosomething ($somevar) {
echo $somevar;
return 1;
}
Function dosomethingelse ($somevar) {
echo $somevar;
return 1;
}
function getmicrotime()
{
list($usec, $sec) = explode(" ", microtime());
return ((float)$usec + (float)$sec);
}
# Benchmark here
$time_start = getmicrotime();
For ($i=0; $i <= 100000; $i++) {
$retval = dosomething($i);
$retval2 = dosomethingelse($i);
}
$time_end = getmicrotime();
$time = $time_end - $time_start;
# end benchmarking
?>
Every time you call "dosomething" and "dosomethingelse", it executes the
function, it just doesn't delare it over again. So even though your
functions are declared outside of your benchmark loop, they still get
executed inside the loop, therefore you get the time needed to execute
100,000 calls of both functions (in this case).
The only thing you're not benchmarking here is the time to declare the
functions once, which is extremely minimal.
Does that clarify it a bit for you?
