line breaks when reading a file

[Christopher Glaeser]

Consider the code:

$arrText = file ("http://www.site.com/page.htm");
for ($i=0; $i<count($arrText); i++) {
echo("$arrText[$i]\n");
}

(I did not test the snippet for errors)

The line breaks appear to be different from the original .htm file. Why?

Best,
Christopher

You're adding a linefeed character to each line of the original
source. Newlines aren't stripped by file; to remove them, the Manual
suggests rtrim. (It actually says you "*need* [emphasis added] to use
rtrim()".)
