Get string value of array on remote server

[adiq]

I'm trying to find the content of an array on a remote server. All I can send back currently is strings (due to limitations in the PHP implementation of xmlrpc). Normally, I'd just use \[code\]var_dump()\[/code\], but that returns void. I've tried using \[code\]var_export\[/code\], but I get XML errors, even when I cast the result to a string.How can I get the string representation of an array?
