HTML Chars

[kbc1]

Hi

I have a free text field that allows users to input text but I would like to be able to convert any characters such as exclamation marks and dashes (! and -) into valid xhtml upon saving without having to do a str_replace for each one - what is the best function for doing this upon the page being submitted?

Thanks

Hi, you can store all the values you want to remove in an array,

e.g.

<?php

$cleanThese = array("!","-","$"); // etc etc etc

$dirtyString = "!!!HELLO, I'm a dirty $tring--!!";

$cleanedString = str_replace($cleanThese, $dirtyString);

// Will return: HELLO, I'm a dirty tring";

?>

Also, if you mean turn all characters into HTML based characters I think htmlspecialchars($var); will work.
