[wp-hackers] Passing Key but Not Value?

[Otto]

Well, the $acronyms array doesn't have the replacement values in it,
so $matches[2] doesn't have anything in it. Nor could it, in fact,
because that's not what you're matching on anyway.

Pretty much, you're just doing it wrong. Try something more like this:

$arr_tmp = array(
'LAN' => 'Local Area Network',
'DHCP' => 'Dynamic Host Control Protocol',
'SSH' => 'Secure Shell',
'FTP' => 'File Transfer Protocol',
'SFTP' => 'Secure File Transfer Protocol',
);
foreach ($arr_temp as $s=>$r) {
$search[] = $s;
$replace[] = "<acronym title='$r'>$s</acronym>";
}
$text= str_replace($search, $replace, $text);

You'll also find that that is one heck of a lot faster than using
regular expression functions.
