This is what I've tried:
$pat = '/( --.*)(\s|\n)/U';
$rpl = '$1$2 ';
while (preg_match($pat,$txt,$matches) > 0) {
print "$txt\n";
printf("[0]: <%s>\n",$matches[0]);
printf("[1]: <%s>\n",$matches[1]);
printf("[2]: <%s>\n",$matches[2]);
preg_replace($pat,$rpl,$txt);
}
The prints are for debugging. $matches contains what I expect but
nothing gets replaced and $txt stays the same so it loops forever.
What am I doing wrong?

If you mean that EVERY space after the -- separator should be
replaced, then just try this:
<?
$txt = "As a rule, kids with meningitis don't smile when looking at
attractive faces -- not even you, Miss America, or the ravishing
pharmacist I mentioned above. -- ER Questions and Answers, Part 3";
function replace_space($txt) {
$field = explode("--",$txt);
for($i=0;$i<(count($field)-1);$i++) $new_txt .= $field[$i];
$new_txt .= "--".str_replace(" "," ",$field[(count($field)-1)]);
return $new_txt;
}
echo replace_space($txt)."\n";
?>
This would print:
A promise is a debt. -- Irish Proverb
Conversely, it will still properly handle the existence of
double-hyphens anywhere else in the quote, but not the source.
Consider this string:
"As a rule, kids with meningitis don't smile when looking at
attractive faces -- not even you, Miss America, or the ravishing
pharmacist I mentioned above. -- ER Questions and Answers, Part 3"
This would still become:
"As a rule, kids with meningitis don't smile when looking at
attractive faces -- not even you, Miss America, or the ravishing
pharmacist I mentioned above.
-- ER Questions and Answers, Part 3"
However, if you have double-hyphens in the source, like so:
"What a pain in the butt this would be! -- Me, sending an
example -- to you
The phrase would be printed like this:
"What a pain in the butt this would be! -- Me, sending an
example -- to you
