1. You need curly braces around the code to be executed within the conditional. 
    if ( index( $fl, '1' ) != -1 )
{
    $flag = 1 ;
}
else
{
    $flag = 0 ;
}

  2. There are many ways to do this. Here's a few, in the order I prefer them:

    1. Use the CGI module from CPAN. 
      print $query->hidden( -name => 'hidden_name', -default => $ph );

    2. Use printf. 
      printf '<input type="hidden" name="phone_number" value="%s">', $ph ;

    3. Use interpolation. 
      print "<input type=\"hidden\" name=\"phone_number\" value=\"$ph\">" ;
