<?php
$t = '<a title="Errors in string parsed from website! 
String containing errors: \'<b>Warning</b>:\'
">i</a>';

echo '-->'.strip_tags($t).'<--'.strlen(strip_tags($t));
echo "\n<br> should be:\n<br>";
echo '-->i<--1';
echo "\n<br> i get:\n<br>";
echo "-->Warning:' \">i<--14 ";
?>

Can someone explain this error? I would be afraid that the function gets confused by
* the extra line feeds
* the nested <b> tags in the title attribute 
  (which should definately not show up!)
