I don't believe there is already an explode() or implode() function.
I'd imagine you could do one like this:
PHP Code:
echo(explode(",", "1, 2, 3, 4, 5, 6", 3));
PHP Code:
function explode(del, str, limit) {
temp.token = str.tokenize(del);
for (temp.i = 0; temp.i < token.size(); temp.i ++) {
if (i < limit) {
temp.output.add(token[i]);
}else {
temp.positions = str.positions(del);
temp.output.add(str.substring(positions[i - 1] + 1));
break;
}
}
return output;
}
Good luck.
