PHP capitalize after dash

Question

$q = durham-region;

$q = ucfirst($q);

$q = Durham-region;

How would I capitalize the letter after the dash (Durham-Region)? Would I have to spli

Answer 1

Yes. ucfirst() simply capitalized the first letter of the string. If you want multiple letters capitalized, you must create multiple strings.

$strings = explode("-", $string);
$newString = "";
foreach($strings as $string){
    $newString += ucfirst($string);
}

function ucfirst_all($delimiter, $string){
    $strings = explode("-", $string);
    $newString = "";
    foreach($strings as $string){
        $newString += ucfirst($string);
    }
    return $newString;
}

It is important to note that the solutions provided here will not work with UTF-8 strings!

$str = "Τάχιστη αλώπηξ βαφής ψημένη γη, δρασκελίζει-υπέρ νωθρού κυνός";
$str = explode('-', mb_convert_case( $str, MB_CASE_TITLE ) );
$str = implode('-', array_map('mb_convert_case', $str, array(MB_CASE_TITLE, "UTF-8")) );
echo $str;

// str= Τάχιστη Αλώπηξ Βαφήσ Ψημένη Γη, Δρασκελίζει-Υπέρ Νωθρού Κυνόσ

Answer 3

Updated Solution

As of PHP 5.5, the e modifier for preg_replace has been deprecated. The best option now is to use one of the suggestions that does not use this, such as:

$q = preg_replace_callback('/(\w+)/g', create_function('$m','return ucfirst($m[1]);'), $q)

or

$q = implode('-', array_map('ucfirst', explode('-', $q)));

Original Answer

You could use preg_replace using the e modifier this way:

$test = "durham-region";
$test = preg_replace("/(\w+)/e","ucfirst('\\1')", $test);
echo $test;
// Durham-Region
