PHP 编码规范(21)
8.3 函数
方法名是一个动词,采用大小写混合的方式,第一个单词的首字母小写,其后单词的首字母大写。
function run();
function runFast();
function getBackground();
通常每个方法都是执行一个动作的,所以对它的命名应该清楚的说明它是做什么的:用checkForErrors()代替errorCheck(),用dumpDataToFile()代替dataFile()。这么做也可以使功能和数据成为更可区分的物体。
有时后缀名是有用的:
Max - 含义为某实体所能赋予的最大值。
Cnt - 一个运行中的计数变量的当前值。
Key - 键值。
例如:retryMax 表示最多重试次数,retryCnt 表示当前重试次数。
有时前缀名是有用的:
is - 含义为问一个关于某样事物的问题。无论何时,当人们看到Is就会知道这是一个问题。
get - 含义为取得一个数值。
set - 含义为设定一个数值
例如:isHitRetryLimit
