Performance - which is faster

[Ferm]

Hi

Say you needed to write alot of dynamic HTML, what would you think is faster (using php5)

1.

//In base class:

function write($append)
{
   $this->out .= $append;
}

funciton flush()
{
   echo $this->out;
   unset ($this->out);
}

//Where the action is
//call write function as much as you need, ex 
$this->write('<div>.....');
...
//and finally do 
$this->flush();

2.
Or just call echo('<div>....'); whenever you need to out put.

So basically this question is: which is faster echoing or appending to string?

Thanks

1. It doesn't matter
2. Benchmark it using your PHP profiler- you do have one, right?
3. If you're worried about the speed of echo(), use output buffering which might help slightly, but I really wouldn't.

Anything else you're doing in the page would be slower than echo - so it really isn't important. Don't optimise something that doesn't matter.

yes, you´re right

No, I didn´t know there was a php profiler. Do you mean the tool from Semantic Designs? or do you have a link

thanks
