Question

how can I encode the contents of the array $varcontent[$i]["images"] as i did with $varcontent[$i]["content"] ?

$encoded = strtr(base64_encode(addslashes(gzcompress(serialize($nospaces),9))), '+/=', '-_,');

$varcontent[$i]["content"] = $encoded;
$varcontent[$i]["images"] = array_unique($filtered);

Thank you!

You want array_map(). Try this:

function encodeElement($e)
{
    return strtr(base64_encode(addslashes(gzcompress(serialize($e),9))), '+/=', '-_,');
}
array_map("encodeElement", $array);
