Child Theme Function Code Error Question

    Hope this is the right forum for this question. I have been trying to use a function added into my child theme to try and block url from being posted in my contact form.

    I’m not that well versed with php so thought I would seek help from someone who is.

    Here is the code:

    function custom_textarea_validation_filter($result, $tag) {
   $type = $tag[‘type’];
   $name = $tag[‘name’];
   //here textarea type name is ‘message’
   if($name == ‘your-message’) {
      $value = $_POST[$name];
      if (preg_match(‘/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i’, $value)){
      $result->invalidate( $tag, “Avoid URLs & Links” );
      }
   }
return $result;
}
add_filter(‘wpcf7_validate_textarea’,’custom_textarea_validation_filter’, 10, 2);
add_filter(‘wpcf7_validate_textarea*’, ‘custom_textarea_validation_filter’, 10, 2);

    And here is the error message:

    [10-Aug-2020 18:04:32 UTC] PHP Parse error: syntax error, unexpected ‘?’ in /home/mywebsite/public_html/wp-content/themes/nikkon-child/functions.php on line 34

    Tried using double question marks and another regex solution but still get the same errors. Any ideas?

    Forgot to add the server info:

    cPanel Version 88.0 (build 13)
    Apache Version 2.4.46
    PHP Version 7.2.33
    MySQL Version 5.7.31
    Architecture x86_64
    Perl Version 5.16.3
    Kernel Version 3.10.0-1127.18.2.el7.x86_64

    Just experimented with this regex 

    if ( '/www\.|http:|https:\/\/[a-z0-9_]+([\-\.]{1}[a-z_0-9]+)*\.[_a-z]{2,5}'.'((:[0-9]{1,5})?\/.*)?$/i' $value)){
$result->invalidate( $tag, “Avoid URLs & Links” );

    and got PHP Parse error: syntax error, unexpected ‘$value’ (T_VARIABLE)

    Will keep digging but some help would be greatly appreciated.

    Not sure why this was moved here because it has nothing to do with the Nikkon theme so you can remove it if you like.
