Answer 1

You can perform rtrim() on the line at the beginning of each loop iteration.

function getProductCount($path)
{
    $count = 0;

    foreach (file($path) as $raw_name) {
        $name = rtrim($raw_name);
        if($name == "<product>")
        {
            $count = $count + 1;
        }
    }
    return $count;
}

Answer 2

Either a regular expression (fetching the last occurence of \n in a line and stripping it) or simple $name = substr($name, 0, -2) would do the trick

Answer 3

you might want to look at: http://php.net/trim and http://php.net/str_replace (so you can replace the eol by an empty character)

Answer 4

http://www.php.net/manual/en/function.file.php

Look at the additional flags you can add to the function call. You should use "FILE_IGNORE_NEW_LINES"

Answer 5

Use trim() or rtrim()(if you want to preserve whitespaces in the beginning of the string) to strip whitespaces.
