//Join same as implode()
$arr=array("First","Second","Third","Four","....+N");

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);
}
?>
