[zartzar]

What's the error?

 

Warning: implode() [function.implode]: Invalid arguments passed in <directory> line number 37 (yeah, where i use the implode function)

[trq]

sort returns a booleen not an array.

 

<?php

$comments=$_POST['comments'];

$parray=explode(' ', $comments);

$parraydup=array_unique($parray);

sort($parraydup);

$pstring=implode(' ',$parraydup);

print $pstring;

?>

[Maq]

That's because sort returns a boolean and you're trying to implode on it.
