Answer 1

In a more detailed manner from Above example, Considering below is your string:

$string = '<div>This..</div> <a>is<a/> <strong>hello</strong> <i>world</i> ! هذا هو مرحبا العالم! !@#$%^&&**(*)<>?:";p[]"/.,\|`~1@#$%^&^&*(()908978867564564534423412313`1`` "Arabic Text نص عربي test 123 و,.m,............ ~~~ ٍ،]ٍْ}~ِ]ٍ}"; ';

Code:

echo preg_replace('/[^A-Za-z0-9 !@#$%^&*().]/u','', strip_tags($string));

Allows: English letters (Capital and small), 0 to 9 and characters !@#$%^&*().

Removes: All html tags, and special characters other than above

Answer 2

to allow periods and any other character just add them like so:

change: '#[^a-zA-Z ]#' to:'#[^a-zA-Z .()!]#'

Answer 3

Remove all special character don't give space write in single line

trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', 
urldecode(html_entity_decode(strip_tags($string))))));
