你會寫注釋么？從我寫代碼開始，這個問題就一直困擾著我，相信也同樣困擾著其他同學。以前的寫注釋總是沒有一套行之有效的標準，給維護和協(xié)同開發(fā)帶了許多麻煩，直到最近讀到了phpdocumentor的注釋標準。

下面對phpdocumentor的注釋標準進行總結：

Type（數(shù)據(jù)類型）:

• 1. string 字符串類型
  2. integer or int 整型
  3. boolean or bool 布爾類型 true or false
  4. float or double 浮點類型
  5. object 對象
  6. mixed 混合類型 沒有指定類型或不確定類型時使用
  7. array 數(shù)組
  8. resource 資源類型 （如數(shù)據(jù)庫查詢返回）
  9. void 空值（控制器返回值經(jīng)常使用）
  10. null null類型
  11. callable 回調函數(shù)
  12. false or true 只返回true or fasle 時使用
  13. self 自身
