PHP Ucwords with or and special characters

Question

Here is what I'm doing.

I have a couple of strings that is uppercase

†HELLO THERE
DAY OR NIGHT

So to convert them, I'm using the following code:

ucwords(strtolower($string));

Here is the end result:

†hello There
Day Or Night

How can I ignore the † or any special characters so it the words can show

†Hello There

and how can I keep words like or all lowercase.

What do you mean by "special characters"? Is "é" a special character? — rap-2-h, Jul 22 '16 at 15:06
Well, I'm talking about any special character like this † (in this case). — Kevin Davis, Jul 22 '16 at 15:08
So how should `†HELLO†THERE†HOW†ARE†YOU` be outputted? — MonkeyZeus, Jul 22 '16 at 15:50

Try:

print preg_replace_callback('#([a-zA-ZÄÜÖäüö0-9]+)#',function($a){
   return ucfirst(strtolower($a[0]));
 },
 '†hello THERE'
);

[a-zA-ZÄÜÖäüö0-9]+ find a word that only has this chars

You can also use this instead [\w]+ see: http://www.regular-expressions.info/wordboundaries.html

preg_replace_callback call a function on the found result

function($a){} do something with the result, here ucfirst(strtolower())

    $lowerString = strtolower($string);
    $stringArray = explode($lowerString, ' ');
    foreach ($stringArray as $key => $singleString) {
        $i = 0; 
        $formatedString = '';
        $upcased = false;
        for ($i; $i < strlen($singleString); $i++) {
            $ascNum = chr($singleString[$i]);
            $word = $singleString[$i];
            if (!$upcased) {
              if (($ascNum >= 65 && $ascNum <= 90) || ($ascNum >= 97 && $ascNum <= 122) ) {
                $word = ucwords($word);
                $upcased = true;
              }
            }
            $formatedString .= $word;  
        }
        $stringArray[$key] = $formatedString;
    }
    $result = implode(' ',$stringArray);

maybe a little complicated, but a clean idea.

ucwords(strtolower("†HELLO THERE"),"† "); the second parameter of ucwords is an optional delimiter. So by including both dagger and space, ucwords will work for the examples provided.

for your second question, see here

Assuming words are separated by a space:

<?php
function custom_ucfirst($s)
{
    $s = strtolower($s);

    $e = (strpos($s, ' ') !== false ? explode(' ', $s) : array($s));

    $keep_all_lowercase = array('or','and','but');

    foreach($e as $k=>$v)
    {
        if(!in_array($v, $keep_all_lowercase))
        {
            $str_split = str_split($v);

            foreach($str_split as $k2=>$v2)
            {
                if(in_array($v2, range('a','z')))
                {
                    $str_split[$k2] = strtoupper($v2);
                    break;
                }
            }

            $e[$k] = implode('', $str_split);
        }
    }

    return implode(' ', $e);
}

echo custom_ucfirst('†HELLO THERE .cloud. or sky what a nice an*d ()good day.');

// †Hello There .Cloud. or Sky What A Nice An*d ()Good Day.
