Camelize一个php字符串

Question

How to convert this type of php string to camel case?

$string = primary-getallgroups-sys

I've tried but just found different solutions to camelize a string with spaces. Like ucword($string), but it just capitalize the first word. When i add a delimeter of hyphen (-), it gives error.

$string = 'primary-getallgroups-sys';

// split string by '-'
$words = explode('-', $string);

// make a strings first character uppercase
$words = array_map('ucfirst', $words);

// join array elements with '-'
$string = implode('-', $words);

echo $string; // is now Primary-Getallgroups-Sys
