textfile in string

Question

all i want is to display the contains from pageset.txt line by line.

$lines = file('pageset.txt');
foreach($lines as $line) {
// do something with $line.
$hh = $line . "<br/>";

echo $hh;

You keep overwriting $hh before echoing out the last line.

Try this instead:

echo nl2br(htmlspecialchars(file_get_contents("pageset.txt")));

file_get_contents to read in the whole file in one go (unsuitable for extremely large files, but still better than file in that regard).
htmlspecialchars to escape any HTML in the file so that, in particular, < is shown correctly. Remove if you actually want to include the file's HTML.
nl2br is a haxy method of adding <br /> to the end of each line. Essentially it's a shorthand for str_replace(PHP_EOL,"<br />".PHP_EOL,$input).

You forgot to add the concatenation operator to your variable assignment:

$hh = '';
$lines = file('pageset.txt');
foreach($lines as $line) {
    // do something with $line.
    $hh .= $line . "<br/>";
}
echo $hh;
