How to properly escape html form input default values in php?

I am facing problem on facing </textarea> element.
I am working on whole php file edit. If the php file has </textarea> tag it closes the files codes.
E.g.

$data=file_get_contents($file);
..
'<textarea>'
'.$data.'
'</textarea>'
..

The problem is:
if contain the </textarea> tag in data, my codes truncted by the tag. Because </textarea> is end tag of textarea values. Any solve there to not execute </textarea> tag(which contained $data)?

Answer 1

Try cleaning up $data before outputting it, such as:

'.htmlentities($data).'

Also, take a look at the available flags for the function in the PHP documentation.
