I have a string which always has "C" then a number which it's length can change anytime and then "P" and then a space and then a word like: echo "C60P1 Unit";

This doesn't match your description... there's a number after the 'P' :)

is it anyway to split the string by type? from the manual I did this: function multiexplode ($delimiters,$string) {

      $ary = explode($delimiters[0],$string);
      array_shift($delimiters);
      if($delimiters != NULL) {
          foreach($ary as $key => $val) {
               $ary[$key] = multiexplode($delimiters, $val);
          }
      }
      return  $ary;

} echo "C60P1 Unit"; $str="C60P1 Unit"; $delimiters = Array("C","P"," "); $res = multiexplode($delimiters,$str); echo '<pre>'; print_r($res); echo '</pre>'; but it seems to me it is so complex for such a small string does anything for type exist which I don't know about to for example just grab the numbers?because I just care about the numbers here 60 and 1 seperately

<?php $str = 'C60P1 Unit'; $num = preg_replace( '#^[^[:digit:]]+([[:digit:]]+).*$#', '\1', $str ); ?>

Sorry, I missed that you want the 60 and the 1... I think others have done similarly but just to be different here's another take: <?php $str = 'C60P1 Unit'; list( $num1, $num2 ) =

    explode( ':', preg_replace( '#^[^[:digit:]]+([[:digit:]]+)[^[:digit:]]+([[:digit:]]+).*$#', '\1:\2', $str ) );

echo $num1."\n"; echo $num2."\n"; ?> Cheers, Rob. -- Phone: 613-822-9060 +++ Cell: 613-600-2836 E-Mail Disclaimer: Information contained in this message and any attached documents is considered confidential and legally protected.
