Yup, the language stole ~32Kb of your memory and used it to speedup the

Ok, in my attempt to send a sane looking example, I cleaned up the problem.
<?php
$str = "This is a medium length string";
$start = memory_get_usage();
for($x=1;$x<=1000000;$x++){
$var = $str." ".$x.": (3.5): ".time()."\n";
}
$first_growth = number_format(memory_get_usage() - $start);
$start = memory_get_usage();
for($x=1;$x<=1000000;$x++){
$var = "$str $x: (3.5): ".time()."\n";
}
$growth = number_format(memory_get_usage() - $start);
echo "first growth: $first_growth\nsecond growth: $growth\n";
?>
The introduction of $x into the string makes the difference.
first growth: 892
second growth: 3,955,068
