一、代码
/**
* 下划线转驼峰
* 思路:
* step1.原字符串转小写,原字符串中的分隔符用空格替换,在字符串开头加上分隔符
* step2.将字符串中每个单词的首字母转换为大写,再去空格,去字符串首部附加的分隔符.
* @param $uncamelized_words
* @param string $separator
* @return string
*/
function camelize($uncamelized_words,$separator='_')
{
$uncamelized_words = $separator. str_replace($separator, " ", strtolower($uncamelized_words));
return ltrim(str_replace(" ", "", ucwords($uncamelized_words)), $separator );
}
/**
* 驼峰命名转下划线命名
* 思路:
* @param $camelCaps
* @param string $separator
* @return string
*/
function uncamelize($camelCaps,$separator='_')
{
return strtolower(preg_replace('/([a-z])([A-Z])/', "$1" . $separator . "$2", $camelCaps));
