You can preg replace capitals with space followed by match and then capitalize the first letter — pvg, Mar 08 '17 at 07:11

preg_replace('/(?<!\ )[A-Z]/', ' $0', $String); will check for the capital letter in the string and insert space. Then by using ucwords you can make it camel case. please check my answer — Sagar Arora, Mar 08 '17 at 07:24

a) You can use ucwords():-

echo ucwords($string);

Output:- https://3v4l.org/sCiEJ

b) In your expected outcome spaces are there, if you want that then do:

echo ucwords(implode(' ',preg_split('/(?=[A-Z])/', 'createWebsiteManagementUsers')));

Output:- https://3v4l.org/v3KUK

try this

$data = preg_split('/(?=[A-Z])/', 'createWebsiteManagementUsers');

$string = implode(' ', $data);

echo ucwords($string);

output will be

Create Website Management Users

Use below code to solve:

$String = 'createWebsiteManagementUsers';
$Words = preg_replace('/(?<!\ )[A-Z]/', ' $0', $String);
echo ucwords($Words);

//output will be Create Website Mangement Users

Don't need to escape the space - `'/(?<! )[A-Z]/'` – James Jul 10 '20 at 03:24

Here is what you need. This has the spaces as well!

function parseCamelCase($camelCaseString){
    $words_splited = preg_split('/(?=[A-Z])/',$camelCaseString);
    $words_capitalized = array_map("ucfirst", $words_splited);
    return implode(" ", $words_capitalized);
}

Thanks

May be you can try something like this

//Split words with Capital letters
$pieces = preg_split('/(?=[A-Z])/', 'createWebsiteManagementUsers');

$string = implode(' ', $pieces);

echo ucwords($string);

//You will get your desire output Create Website Management Users

100% Most Efficient :

$word = 'camelCase'; // expected: Camel Case
$sentence = modifyWord($word);

function modifyWord($word)
{
    $splittedWord = str_split($word);
    $modifiedSentence = ucwords($splittedWord[0]);

    for($i = 1; $i < count($splittedWord); $i++){

        // ASCII : A => 65, Z => 90
        // check if the letter is between A & Z

        if(ord($splittedWord[$i]) >= 65 && ord($splittedWord[$i]) <= 90){
            $modifiedSentence .= ' '.$splittedWord[$i];
        }else{
            $modifiedSentence .= $splittedWord[$i];
        }
    }
    
    return $modifiedSentence;
}

Fixed version with UPPER letter check and symbols

<?php
$word = 'UniCredit Bank (AA)'; // expected: Camel Case
$word = 'CamelCase with space (CAPITAL_NAME) and strangEEword'; // expected: Camel Case
$sentence = modifyWord($word);

echo $sentence;

function modifyWord($word)
{
    $splittedWord = str_split($word);
    $modifiedSentence = ucwords($splittedWord[0]);

    for($i = 1; $i < count($splittedWord); $i++){

        // ASCII : A => 65, Z => 90
        // check if the letter is between A & Z
        
        $nextCapital = isset($splittedWord[$i+1]) && ord($splittedWord[$i+1]) >= 65 && ord($splittedWord[$i+1]) <= 90;
        $prevCapital = isset($splittedWord[$i-1]) && ord($splittedWord[$i-1]) >= 65 && ord($splittedWord[$i-1]) <= 90;
        

        if(ord($splittedWord[$i]) >= 65 && ord($splittedWord[$i]) <= 90 && !$nextCapital && !$prevCapital){
            $modifiedSentence .= ' '.$splittedWord[$i];
        }else{
            $modifiedSentence .= $splittedWord[$i];
        }
    }
    
    return $modifiedSentence;
