hello everybody i have a question regarding strip_tags function.
i have an html document like that.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<p>er</p>
</body>
</html>

and this php script

<?php
$file = "ht.html";
$fp = fopen($file, "r");
$data = fread($fp, filesize($file));
fclose($fp);
$output = str_replace("\t|\t", "|", $data);
$outputline = explode("\n", $output);
$lexeisline=count($outputline);

for ($i = 0; $i < $lexeisline; $i++){
    $outputline[$i]=strip_tags($outputline[$i]);
      if (empty($outputline[$i])){
          unset($outputline[$i]);
}
}
$outputline = array_values($outputline);
$lexeisline=count($outputline);
echo "<p>";
for ($i = 0; $i < $lexeisline; $i++){
echo ($outputline[$i])."<br />";
}
echo "</p>";
?>

the problem is that it does not unset the empty vars(which are returned from the strip_tags) and echos something like this. does the following means that it echos empty strings?
any opinion or help will be very appreciated. Thanx in advance

    This code seems incredibly baroque for what you are doing. Does the following code do what you need?

    $lines = file('ht.html');
$lines = array_map('strip_tags', $lines);
$lines = array_map('trim', $lines);
$lines = array_filter($lines);

echo "<p>\n", implode("<br />\n", $lines), "\n</p>";
