Sintax Error [4.4.2.]

Hi Giuseppe,
I updated your Sendit plugins uploaded in the website.

He gave me syntax error and, therefore, I opened the file and deleted all the php because otherwise you could not see the site. Can you tell me what is the error so that I can correct it and reload the module in the plugin?

Here it is, he gives me the 5 line syntax error.

<? Php

require_once (‘CssToInline / CssToInlineStyles.php’);

use \ TijsVerkoyen \ CssToInlineStyles \ CssToInlineStyles;

function inline_newsletter ($ css, $ content) {
     // Create instance
     CssToInlineStyles CssToInlineStyles $ = new ();

         $ CssToInlineStyles-> setHTML ($ content);
         $ CssToInlineStyles-> setCSS ($ css);

         // output
     return $ cssToInlineStyles-> convert ();

}
?>
