Quite, not a 100%, but highly probable. A small test:
<?php
$i = 0;
function check($string){
global $i;
$i++;
return $string;
}
printf('%1$s %1$s %1$s',check('<br />We\'ll see'));
echo $i;
echo check('<br />and now:');
echo $i;
?>
Returns:
We'll see
We'll see
We'll see1
and now:2
$i = 1, evaluated one time only.
Grtz,
