Hello everyone.

I am working on website and I am trying to make it fast as much as possible - especially the small things that can make my site a little bit quicker.

So, my to my question - I got loop that run 5 times and in each time it echo something, If I'll make variable and the loop will add the text I want to echo into the variable and just in the end I'll echo the variable - will it be faster?

loop 1 (with the echo inside the loop)

for ($i = 0;$i < 5;$i++)
{
    echo "test";
}

loop 2 (with the echo outside [when the loop finish])

$echostr = "";
for ($i = 0;$i < 5;$i++)
{
    $echostr .= "test";
}
echo $echostr;

I know that loop 2 will increase a bit the file size and therefore the user will have to download more bytes but If I got huge loop will it be better to use second loop or not?

Thanks.
