Hi,

 

I use a form and get the post value of a textarea field in a variable.

How do i Parse the pre tag and so htmlentities to the data present inside the pre tag. please help.

Um, what? Is this what you want?:

 

echo '<pre>' . htmlentities($_POST['fieldname']) . '</pre>';

Else ask a proper question; no offence.

Hmm my preg_replace is a skills are a little iffy.

 

<?php

echo preg_replace_callback("/<(pre)>(.*?)<\/\\1>/ism", create_function("$matches", "return htmlspecialchars($matches[2]);", $input);

?>

 

I'm not sure if you have to backslash < and > or not in regular expressions. so you might have to come back

Oh, maybe that was what the OP meant You just have to use single quotes instead of double quotes in order for it to work. And your pattern could simply be

 

'~<pre>(.*?)</pre>~is'

 

And then use $matches[1] in the replacement.

Kind of getting off topic and all, but what's the difference between ~, /, % and a couple other things like that for surrounding the search? Can't seem to find that stuff on regularexpressions.info

They're called pattern delimiters, and can be any non-white space, non-alphanumeric ASCII character (except a backslash). And it's always smart to use delimiters that don't appear within the pattern, so you don't have to escape them.
