This might be a silly question but it struck me, and here i ask.
<?php
$x="Hi";
$y=" There";
$z = $x.$y;
$a = "$x$y";
echo "$z"."<br />"."$a";
?>
$z uses the traditional concatenation operator provided by php and concatenates, conversely $a doesn't,
My questions:
a. by not using the concatenation operator, does it effect the performance?
b. If it doesn't why at all have the concatenation operator.
c. Why have 2 modes of implementation when one does the work?
