PHP Ucwords with or and special characters - php

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.

Answer 1

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())

Answer 2

$lowerString = strtolower($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.

Answer 3

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

Answer 4

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.
