Help! highlight_string()

[Justin Sampson]

Hey,
I'm trying to get highlight_string() to work, here's my code:

<form action="<? echo "$PHP_SELF" ?>" method="POST">
<input type="texbox" rows="6" cols="9" name="foo"><input type="submit">
</form>
Results:
<?
htmlspecialchars($foo);
highlight_string($foo);

?>

But I get this error:

Warning: Unexpected character in input: '\' (ASCII=92) state=1 in c:\webdocs\hilite.php on line 7

Anyone know whats wrong?

Thanks,
Justin Sampson

Unfortunately highlight_string() needs to have <? ?> tags present in order to work, and it seems that you must replace \ with '' before it will work with that sort of character, I got it to work this way

<form action="<?=$PHP_SELF?>" method="POST">
<input type="texbox" rows="6" cols="9" name="foo"><input name="submit" type="submit" value="submit">
</form>
Results:
<?
if($submit) {
    $foo = addslashes($foo);
    $foo = htmlspecialchars($foo);
    $foo = str_replace('\\', '', $foo);
    highlight_string("<? print $foo; ?>");
    }
?>

Freddy, I also was trying to do this however there was a problem since the [*PHP] tags in vBulletin remove the \'s.

I think you gotta put in the [*CODE] tags.

Thanx Allot...

Ok, see, what I'm trying to do is add a [ php ] feature to my forum. I can get everything between the [ php ] and [/ php ] tags into a variable, just can't get the highlight to work.

Justin so just add <? and ?> to each side of the var that holds the stuff betweeen the

 and 

tags when using highlight_string() and remember to str_replace out any unwanted vars and then run highlight_string()
