trying to produce single-line NSLOOKUP string

[ppowell]

$msg = preg_replace('/[\n\r]/', '<br />', preg_replace('/[\s\t]/',' ',nl2br(htmlspecialchars(shell_exec("nslookup -retry=4 -timeout=2 -type=mx $host 2>&1")))));

I am simply trying to produce a single-line NSLOOKUP return string, instead
I get HTML-mangled garbage every time, break tags clobbered by ampersands,
space fields clobbered by mangled HTML break tags, all kinds of trash.

Could someone help me put this together again for it to produce a
single-line NSLOOKUP string?

Thanx
Phil

sometimes "streamline" isnt better

break that monster into some variables... wont hurt
