This won't work for me as I have 500+ records to sort based on the score key.. looking at jochem's class now. Thanks

which wont help much - assuming what you say is true (why wont it work? have you tried it). sort method from the class:

    function sort()
    {
       if(count($this->sortKeys)) {
           usort($this->dataArray, array($this,"_sortcmp"));
       }
    }

Thanks jochem, I had a second look at it and I figured it out. I had problem implementing it with a class but now I have figured how to use it. cheers, Jeffery

ok, does that mean using usort() on your array works? my class is just a fancy wrapper around usort - and ofcourse it allows you to sort on more than 1 'column' in the second dimension of the array (kind of like a multi-column sort in an SQL statement). -- the point being that the usort() example Kurt (I think that was his name) sent would work also. anyway glad you could use it. :-) .... Yes the example sent by Kurt Yoder worked for me. I coudn't work out the errors with the class you sent me. I realised it was written for PHP5 in mind ?... or maybe I wasn't patient enough to spent time debugging it :-(

/** * This function is to sort a multi-dimentional array. This is a call-back function. * Replace the value of $this->mArraySortKey with the appropriate key * before calling the call-back function */ function sort_array($x, $y) { if ( $x[$this->mArraySortKey] == $y[$this->mArraySortKey] )

     return 0;

else if ( $x[$this->mArraySortKey] < $y[$this->mArraySortKey] )

     return 1;

else

     return -1;

} and within my class I am calling the following two lines: // Sort the array $this->mArraySortKey = 'score'; usort($this->mSearchData, array(& $this, 'sort_array')); cheers, Jeffery Fernandez http://melbourne.ug.php.net
