Here is a handy function that makes the first letter of everything in a
sentence upercase. I used it to deal with titles of events posted on my
website ... I've added exceptions for uppercase words and lowercase words
so roman numeral "IV" doesn't get printed as "iv" and
words like "a" and "the" and "of" stay
lowercase.
function RemoveShouting($string)
{
$lower_exceptions = array(
"to" => "1",
"a" => "1", "the" => "1",
"of" => "1"
);
$higher_exceptions = array(
"I" =>
"1", "II" => "1", "III" =>
"1", "IV" => "1",
"V"
=> "1", "VI" => "1", "VII"
=> "1", "VIII" => "1",
"XI" => "1", "X" => "1"
);
$words = split(" ", $string);
$newwords = array();
foreach ($words as $word)
{
if
(!$higher_exceptions[$word])
$word =
strtolower($word);
if (!$lower_exceptions[$word])
$word = ucfirst($word);
array_push($newwords, $word);
}
return join(" ", $newwords);
}
