  use the explode function

  $source  = "12345.567843";
  $result = explode(".", $source);
  echo $result[0]; // 12345
  echo $result[1]; // 567843

  <?php
  $str = "12345.567843";
  $arr = explode(".", $str);
  print_r($arr);
  

  Outputs:

  Array
  (
      [0] => 12345
      [1] => 567843
  )

  GOD BLESS OVERKILLING

  preg_match_all('|([0-9]*)\.([0-9]*)|', $in, $out);
  
  print_r($out);

  <?php
  preg_match('/([0-9]+)\.([0-9]+)/', $str, $regx);
  array_shift($regx);
  print_r($regx);

  But regex's are so slow

  $value = 12345.567843;
  $first_part = floor($value);
  $second_part = str_replace("${first_part}.", '', $value);
  

  In reality I'd probably do:

  list($first_part,$second_part) = explode('.', $value);

  After first testing that $value is in the expected format.

  I feel like we should have a competition to see who can do this using the most code.

  It's interesting to see how many different ways a simple task can be accomplished

  I can take a nap while that preg_match is running ;-)

  $value = "12345.567843";
  $first_part = strtok($value, '.');
  $second_part = strtok('.');

  What no sed or awk? This thread would not be complete without it.

  $firstpart = '';
  $lastpart = '';
  $array = array();
  $string = '12345.567843';
  $stringsize = strlen($string);
  
  for($i=0; $i<$stringsize; $i++)
  {
     $array[] = $string[$i];
     if($string[$i] == '.')
     {
         $dotposition = $i;
     }

  foreach($array as $key => $val)

  This only removes the decimal. Too lazy to figure out the rest.

  echo '12345.567843' | sed 's/.//g'

  echo '12345.567843' | sed 's/.//g'

  That removes everything.

  I guess that you mean echo '12345.567843' | sed 's/\.//g'

  Yeah, silly forum engine.

  Thanks for catching that. Yea, posted without the {code} tags at first and it must have stripped that.

  print substr($word, 0, strpos($word,".")). " ". substr($word, strpos($word,".")+1);
