Question

I have to split each word and compare it with in-built local dictionary and replace it with the equivalent word in another language.When I split a words with special characters (*eg:*of!) it will not match with dictionary even if they are the same.

Now I need to replace those special characters by empty strings.

$opis="of!";
$a=preg_replace('!"#$%&/()=?*+'-.,;:_', '', $opis);
print_r($a);

Answer 1

You can use str_replace or preg_replace

Example preg_replace http://php.net/manual/en/function.preg-replace.php

  $str = preg_replace("/\W+/", '', $str);
  var_dump($str);

Example str_replace http://php.net/manual/en/function.str-replace.php

$search =  '!"#$%&/()=?*+\'-.,;:_' ;
$search = str_split($search);
$str = "OF!" ;

var_dump(str_replace($search, "", $str));

Output

string 'OF' (length=2)
