function remove_unwanted( $var )
{
    static $allowed_chars = '!"#$%&\'()*+,-.\\/0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~';
    return preg_replace( '/[^' . $allowed_chars . ']/', '', $var );
}

PHP:

 

Hello,

this worked kind of. but

There is no space between words. All the words came together and there is no line breaks as well.

thanks

 

Add spaces and line breaks into the allowed chars list then...

 

I do not know how to add <br> to this code.

<?php

function remove_unwanted( $var )
{
    static $allowed_chars = "!\"#$%&'()*+,-.\\\\\\/0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ\\[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~ \n";
    return preg_replace( '/[^' . $allowed_chars . ']/', '', $var );
}

echo remove_unwanted('New<br />[]éépost' . "\n" . '<br>asdaéá');
// Example

PHP:

Returns:

New<br />[]post
