How can I make upper-case the first character of each word in a string accept a couple of words which I don't want to transform them, like - and, to, etc?
For instance, I want this - ucwords('art and design')
to output the string below,
'Art and Design'
is it possible to be like - strip_tags($text, '<p><a>')
which we allow
and in the string?
or I should use something else? please advise!
thanks.
None of these are really UTF8 friendly, so here's one that works flawlessly (so far)
function titleCase($string, $delimiters = array(" ", "-", ".", "'", "O'", "Mc"), $exceptions = array("and", "to", "of", "das", "dos", "I", "II", "III", "IV", "V", "VI"))
{
/*
* Exceptions in lower case are words you don't want converted
* Exceptions all in upper case are any words you don't want converted to title case
* but should be converted to upper case, e.g.:
* king henry viii or king henry Viii should be King Henry VIII
*/
$string = mb_convert_case($string, MB_CASE_TITLE, "UTF-8");
foreach ($delimiters as $dlnr => $delimiter) {
$words = explode($delimiter, $string);
$newwords = array();
foreach ($words as $wordnr => $word) {
if (in_array(mb_strtoupper($word, "UTF-8"), $exceptions)) {
// check exceptions list for any words that should be in upper case
$word = mb_strtoupper($word, "UTF-8");
} elseif (in_array(mb_strtolower($word, "UTF-8"), $exceptions)) {
// check exceptions list for any words that should be in upper case
$word = mb_strtolower($word, "UTF-8");
} elseif (!in_array($word, $exceptions)) {
// convert to uppercase (non-utf8 only)
$word = ucfirst($word);
}
array_push($newwords, $word);
}
$string = join($delimiter, $newwords);
}//foreach
return $string;
}
Usage:
$s = 'SÃO JOÃO DOS SANTOS';
$v = titleCase($s); // 'São João dos Santos'
since we all love regexps, an alternative, that also works with interpunction (unlike the explode(" ",...)
solution)
$newString = preg_replace_callback("/[a-zA-Z]+/",'ucfirst_some',$string);
function ucfirst_some($match)
{
$exclude = array('and','not');
if ( in_array(strtolower($match[0]),$exclude) ) return $match[0];
return ucfirst($match[0]);
}
edit added strtolower()
, or "Not" would remain "Not".
I know it is a few years after the question, but I was looking for an answer to the insuring proper English in the titles of a CMS I am programming and wrote a light weight function from the ideas on this page so I thought I would share it:
function makeTitle($title){
$str = ucwords($title);
$exclude = 'a,an,the,for,and,nor,but,or,yet,so,such,as,at,around,by,after,along,for,from,of,on,to,with,without';
$excluded = explode(",",$exclude);
foreach($excluded as $noCap){$str = str_replace(ucwords($noCap),strtolower($noCap),$str);}
return ucfirst($str);
}
The excluded list was found at: http://www.superheronation.com/2011/08/16/words-that-should-not-be-capitalized-in-titles/
USAGE: makeTitle($title);
You will have to use ucfirst and loop through every word, checking eg an array of exceptions for each one.
Something like the following:
$exclude = array('and', 'not');
$words = explode(' ', $string);
foreach($words as $key => $word) {
if(in_array($word, $exclude)) {
continue;
}
$words[$key] = ucfirst($word);
}
$newString = implode(' ', $words);
这个怎么样 ?
$string = str_replace(' And ', ' and ', ucwords($string));
