If the string is bigger then 50 chars long, I need to split it. The maximum allowed is 3 chunks of 50. It could be less then 50 but never more then 150. I don't need any special chars to be added, or to serve as "splitters"; I can break the string anywhere, no problem, since the propose is not for showing it to the user.

if (strlen($street) > 50)
{
  $streetPart1 = substr($street,0,50);
  $streetPart2 = substr($street,51,100);
  $streetPart3 = substr($street,101,150);
}

Bunu yapmak için daha zarif bir yolu var mı?

GÜNCELLEME:

Ne varmak bir örnek sonraki:

if (strlen($street) > 50)
{
   $streetPart1 = substr($street,0,50);

   $streetPart2 = substr($street,51,100);

   $streetPart3 = substr($street,101,150);

   if(!empty($streetPart2) && empty($streetPart3) 
   {
      //add part2 only.
   }elseif(!empty($streetPart2 && !empty($streetPart3))
   {
     //add part 2 and part 3
   }
}

Thanks a lot. MEM
