A different approach to REGEX will be to iterate over the word and check if there is an uppercase letter, insert an space before and lowercase the letter

REGEX的另一种方法是迭代单词并检查是否有大写字母,在字母之前插入空格和小写字母

$label = 'myFullName';

$new_word='';

for($i=0, $n=strlen($label); $i<$n; $i++){

     $new_word .= strtoupper($label[$i]) == $label[$i] 
        ? ' '.strtolower($label[$i]) 
        : $label[$i];
}

echo $new_word;

//Output
//my full name
