Very useful function i have using: joinr (join-recursive).

It allows you easy join of multi-level arrays.

For example, if you have

  $intervals = array(array(5, 9), array(11, 15), array(22, 24))

and want to have comma-separated list of dash-separated intervals, just do

  print joinr(array(",","-"), $intervals);



Here is function code:

<?php

    function joinr($join, $value, $lvl=0)

    {

        if (!is_array($join)) return joinr(array($join), $value, $lvl);

        $res = array();

        if (is_array($value)&&sizeof($value)&&is_array(current($value))) { // Is value are array of sub-arrays?

            foreach($value as $val)

                $res[] = joinr($join, $val, $lvl+1);

        }

        elseif(is_array($value)) {

            $res = $value;

        }

        else $res[] = $value;

        return join(isset($join[$lvl])?$join[$lvl]:"", $res);

    }

?>
