    echo 'didnot match';

Answer 1

Vous ne pouvez pas insérer de nouvelle ligne et d'espace dans le code html. Regardez

   <td colspan="3"> 
        Corp off: I – 128, 2nd Floor, Mohammadpur, Bikaji, New Delhi 110066. 
<br>

         </td> 

Chaque saut de ligne ont des symboles de nouvelle ligne. Il y a beaucoup d'espaces avant <td>
