以下是将破折号转换为驼峰命名法的PHP代码 −

示例输入 − this-is-a-test-string

示例输出 − thisIsATestString

注意 − 不需要使用正则表达式或回调函数，可以使用ucwords函数实现。

function dashToCamelCase($string, $capitalizeFirstCharacter = false) {
   $str = str_replace(' ', '', ucwords(str_replace('-', ' ', $string)));
   if (!$capitalizeFirstCharacter) {
      $str[0] = strtolower($str[0]);
   }
   return $str;
}
echo dashToCamelCase('this-is-a-string');

For PHP version>=5.3, the below code can be used −

function dashToCamelCase($string, $capitalizeFirstCharacter = false) {
   $str = str_replace('-', '', ucwords($string, '-'));
   if (!$capitalizeFirstCharacter) {
      $str = lcfirst($str);
   }
   return $str;
echo dashToCamelCase('this-is-a-test-string');

The 'lcfirst' function needs to be used instead of 'strtolower'.
