Split a line through an uppercase letter utf-8

Question

upd. with Latin as well as with Cyrillic
~~I have a code that works fine with Latin characters, but when utf-8~~ removes the first letter of the word, Array ([0] => hello [1] => imon [2] => orobka)

$capitals = array("Л","К"); $word_break = "приветЛимонКоробка"; $word_break = str_replace($capitals, '/',$word_break);

please tell me how to be without regular expressions

Because stupidly replaces the specified letters with a slash.
@ Ipatiev, why should I write lies?) With a Latin alphabet, the array is filled with words from the first letter, nothing is cut off.

Of course, you should do this on regulars, but if you really want the option without them:

 $capitals = array("Л","К"); $word_break = "приветЛимонКоробка"; foreach($capitals as $e){ $word_break=str_replace($e, '/'.$e, $word_break); }

Your example can be slightly modified:

 $capitals = array("~(Л)~", "~(К)~"); $word_break = "приветЛимонКоробка"; $word_break = preg_replace($capitals, '/$1', $word_break); echo $word_break; // привет/Лимон/Коробка

And if the binding is needed not to specific letters, but to all capital letters, then you can:

 $word_break = "приветЛимонКоробка"; $word_break = preg_replace('~[А-ЯЁ]~u', '/$0', $word_break); echo $word_break; // привет/Лимон/Коробка
