Porters Stemming Algorithm

[Richard Hyett]

I dug out a PHP version of Porters Algorithm from
:-http://www.tartarus.or g/~martin/PorterStemmer/php.txt

Whenever I try and run it I'm getting the error
"Wrong parameter count for join() "

Can anyone guess what I am doing wrong, I haven't modified the class
so I assume its the way I'm calling it.

Richard


************* code to call class *************** ******
<?php
require("stemmi ng.inc");

$string="compuT ing";
$string=strtolo wer($string);
echo $string;
$stm=new stemming();
$stm->reset();
for($i=0;$i<str len($string);$i ++)
$stm->add(substr($st ring,$i,1));

$stm->stem(0);
$stem = $stm->toString(); //stem of the string
echo $stem;
?>
*************** *** end code*********** *************** *

What version of PHP are you running? The URL you posted contains a
single-parameter usage of join; join's second parameter is only optional from
PHP 4.3.0 onwards. See the PHP manual.

Thanks Andy, that helped me sort it out. I stuck in the 'glue' parameter ""
rather than upgraded the PHP, the quickest option!
