You should use htmlspecialchars  It replaces characters as below    amp   ampersand  becomes  amp amp   quot   double quote  becomes  amp quot  when ENT NOQUOTES is not set     single quote  becomes  amp  039  only when ENT QUOTES is set   lt   less than  becomes  amp lt   gt   greater than  becomes  amp gt

You can use htmlentities when echoing to the browser  this will show the tag rather than have html interpret it   See here http   uk3 php net manual en function htmlentities php  Example    echo htmlentities   lt strong gt Look just like this line - so then know how to type it lt  strong gt        Output    lt strong gt Look just like this line - so then know how to type it lt  strong gt

As many others have said  htmlentities   will do the trick    but it will look like shit   Wrap it up with a  lt pre gt  tag and you ll preserve your indentation   echo   lt pre gt    echo htmlspecialchars  YOUR HTML   echo   lt  pre gt
