'When using the substr() string function, Why is a litteral carriage return twice as long as a line feed character "\n"?

When typing the following code ... (easily testable with W3schools' editor)

<?php
$basecss = '.class {
    margin-bottom:0
}
/*1234567890';

$basemincss = ".class {\n\tmargin-bottom:0\n}\n/*1234567890";

echo substr($basecss,0,35).'*/';
echo '<br><br>';
echo substr($basemincss,0,35).'*/';
?>

... The results are :

.class {
    margin-bottom:0
}
/*12*/

.class {
    margin-bottom:0
}
/*12345*/

So why does replacing a string's return carriages by line feed characters also reduces its length?
