PHP代码命名规范(PHP Coding Standard) -- 精要
本文从 PHP Coding Standard 抽出最核心精要让开发小组的代码看起来很统一。I. Names
1. Class Names
* Use upper case letters as word separators, lower case for the rest of a word
* First character in a name is upper case
* No underbars ('_')
class name : camel style, start with upper case
2. Method Names/Class Attribute Names/Method Argument Names
* Use the similar rule as for class names. The only difference is the first letter must be lower case.
3. Variable Names
*use all lower case letters
* use '_' as the word separator.
4. Function Names
* For PHP functions use the C GNU convention of all lower case letters with '_' as the word delimiter.
II. Formatting
1. Indentation/Tabs/Space Policy
* Indent using 2 spaces for each level.
* Do not use tabs, use spaces. Most editors can substitute spaces for tabs.
* Indent as much as needed, but no more. There are no arbitrary rules as to the maximum indenting level. If the indenting level is more than 4 or 5 levels you may think about factoring out code.
2.Braces {} Policy
Traditional Unix policy of placing the initial brace on the same line as the keyword and the trailing brace inline on its own line with the keyword:
if ($condition) { while ($condition) {
... ...
} }
III. Miscellaneous
1. PHP Code Tags
Use <?php ?> .
<?php ?> is always avaliable in any system and setup.
