Doesn't work htmlentities(); in my host! HELP

Hello,

I'm hosted my tagboard at PHONEACCESS hosting, and its PHP does not accept htmlentities(); or htmlspecialchars(); and I need help to solve those fails for avoid injections in my script by codes as <script>, <a href>...

Part of code is

$mensaje = htmlspecialchars(trim($_POST['mensaje'], ENT_QUOTES));

PHP:

Please help me to another way for avoid this without htmlspecialschars().

 

You should close trim()'s parenthesis after the $_POST variable. At the moment you're applying ENT_QUOTES to trim(), and not htmlspecialchars().

 

Nothing, I using thus:

$mensaje = htmlspecialchars(trim($_POST['mensaje']), ENT_QUOTES);

But doesn't work yet. HELP ME :S

THE PROBLEM IS, THAT MY HOST DOESN'T ACCEPT HTMLENTITIES(); FUNCTION, WHAT CAN I DO IN THIS SITUATION?

 

I almost can't imagine it being a problem with the host. Why on earth would they disable one of the most basic and harmless functions?

However, you can use str_replace() to emulate the function. But I guess it's a usage error, rather than a problem with the host...
