Re: [PHP] Inserting leading 0 infront of a variable

[Andrey Hristov]

This seems an endless loop for me. You do not alter the $myrowp[topic_id] so its 
length is untouched => if it is <6 you will never
get away from the loop. May be you want this.

   # create topic number  6 digit
$count=strlen($myrow[topic_id]) ;
   while ($count-- < 6){
$leading_digits .= '0';
   }
   $topic_id = $leading_digits.$myrow[topic_id] ;

Best regards,
Andrey Hristov

[Rasmus Lerdorf]

$leading_digits = '0' . $leading_digits;

although what you probably want is strpad() or sprintf()

[PHP] Inserting leading 0 infront of a variable

[Andy]

Hi guys,

is there a possibility to add a string in front of a veriable like the .=
commands adds it to the end? I would like to create a 6 digit number out of
a e.g. 2 digit one. Underneath is my not working code. Maybe someone knows
how to solve that.

Thanx Andy

  # create topic number  6 digit
  while (strlen($myrow[topic_id]) < 6){
   $leading_digits .= '0';
  }
  $topic_id = $leading_digits.$myrow[topic_id] ;
