本篇文章教大家实现驼峰命名和下划线命名互转,在php开发中经常需要两种命名法互相转换,下面为大家提供两种实现方式.

第一种方法效率相对差一些,实现方式如下:

 //驼峰命名转下划线命名
function toUnderScore($str)
{
    $dstr = preg_replace_callback('/([A-Z]+)/',function($matchs)
    {
        return '_'.strtolower($matchs[0]);
    },$str);
    return trim(preg_replace('/_{2,}/','_',$dstr),'_');
}
 
//下划线命名到驼峰命名
function toCamelCase($str)
{
    $array = explode('_', $str);
    $result = $array[0];
    $len=count($array);
    if($len>1)
    {
        for($i=1;$i<$len;$i++)
        {
            $result.= ucfirst($array[$i]);
        }
    }
    return $result;
}

第二种方法更为巧妙高效,推荐使用第二种方法

/**
* 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.
*/
function camelize($uncamelized_words,$separator=&#39;_&#39;)
{
    $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:
* 小写和大写紧挨一起的地方,加上分隔符,然后全部转小写
*/
function uncamelize($camelCaps,$separator=&#39;_&#39;)
{
    return strtolower(preg_replace(&#39;/([a-z])([A-Z])/&#39;, "$1" . $separator . "$2", $camelCaps));}
