The easiest way (I would think) is to run them both in a loop. Run option 1 1000 times, and record the start time and end time, output the total time it took to run it. Do the same with option 2 and compare the results.

How would one test something like this? Testing for performance is something I would like to start doing but I don't know where/how to start.

No offense meant, but when I have a question like that, I test it and find out. Why ask the list for something you could test yourself?

Hi, I have a quick (and probably silly) question. Is there performance
difference between the following two snippets. Does it make a
difference if there are hundreds+ of lines?

<?php
$content = "this is the start of a bunch of lines";
$content .= "another line";
$content .= "yet another";
echo $content;
?>

vs.

<?php
echo "this is the start of a bunch of lines";
echo "another line";
echo "yet another";
?>
