Good idea Nick, in my case above I only needed the first instance, but I like your approach which is a more general implementation.
I am yet to try your code, will let you know how I get on.

If your function works well I will add it to my post thanks

********************************

function explode_between($content, $start, $end, $max) {
if ((isset($max)) && ($max == 0)) {return FALSE;}
if (isset($max)) {$max–- ;}

@$temparray = explode($start,$content,2);
if (count($temparray) < 2) {return FALSE;}
@$temparray = explode($end,$temparray[1],2);
if (count($temparray) < 2) {return FALSE;}

$returned = explode_between($temparray[1], $start, $end, $max);
if ($returned === FALSE) {$outarray = array();}
else {$outarray = $returned;}

array_unshift($outarray,$temparray[0]);
return $outarray;
};

How about this re-entrant function:

function explode_between($content, $start, $end, $max) {
if ((isset($max)) && ($max == 0)) {return FALSE;}
if (isset($max)) {$max– ;}

@$temparray = explode($start,$content,2);
if (count($temparray) < 2) {return FALSE;}
@$temparray = explode($end,$temparray[1],2);
if (count($temparray) < 2) {return FALSE;}

$returned = explode_between($temparray[1], $start, $end, $max);
if ($returned === FALSE) {$outarray = array();}
else {$outarray = $returned;}

array_unshift($outarray,$temparray[0]);
return $outarray;
}

It would be nice if it returned an array of all the substrings between these start and end delimiters e.g.

$array = getStringsBetween($content,$start,$end,$maxcount)

This would be similar to the format for explode() and could be called explode_between()
