HTML check function

[Snoopie]

I need a function or so to check if a string is a HTML tag that I have allowed and if it is not replace < with &lt; and > with &gt;

This is because i have a user/profile system on my site and some people use < etc. in their profile.. i.e. "<3"

take a look at

• highlight-string
• str_replace

and regular expressions?

I'm assuming you've checked out

• strip_tags

Yes I have.. And I'm guessing I need some regular expressions but I am pretty lost in this.. And I was thinking if someone could help..

strip_tags won't work cos i.e. when someone writes '<3' it will think of it as a tag and strip it and everything after it.

try

$good = array( '<', '&gt');
$bad = array('<', '>');
$text = "<b>Wow</b>";
echo $text . '<br>';
$text = str_replace($bad, $good, $text);
echo $text;

are you actually expecting people to submit html code?

if not, why not use
[man]htmlentities[/man] or [man]htmlspecialchars[/man] to convert the html characters?

[Snoopie]

Yes I am expecting people to submit html code.. Which is why I want to allow tags like "<table>", "<tr>", "<td>" and so on..

I need a function where I can set allowed tags, and else replace with htmlentities or htmlspecialchars

can noone help me?

[sarahk]

Why are people writing raw html anyway?

With tools like bbcode or putting in a wysiwg editor you can control what html tags they're allowed and which they're not. Sounds much easier to me.

I think u'r misunderstanding me

$text = $gettextfromdb;
$text = strip_tags('$text', '<a>,<b>'); //etc.
echo $text

This is kinda how it looks..

But then if people write stuff like '<3' in their text it will strip it, and everything after that untill a '>' occurs.. That is my problem.
