Question

I know that sprintf() allows to format string. How can I insert special character(tab in my case)?

10 tab chars("\t") after that symbol s.

Like this:

sprintf("%'\t's","str") = "*morespices*str"

This work::

sprintf("%'a10s","str") = "aaaaaaastr"
sprintf("%' 10s","str") = "       str"

Answer 1

This works fine for me:

<?php
  echo sprintf("f%'\t10sf", 'str');

Result:

f                           strf
