PHP Development Website Code Writing specification

The name of a variable

A) All letters use lowercase

b The first letter is specified according to the variable value type

I. Integer i

Ii. floating-point number F

Iii. string S

Iv. Boolean value B

V. Array A

Vi. object o

Vii. Resources R

Viii. Mixed Type M

C Use ' _ ' as a dividing line for each word

For example:

$i _age_max = 10;

$f _price = 22.5;

$s _name = ' Harry ';

$b _flag = true;

$a _price = Array ();

$o _object = new Class ();

$r _file = fopen ();

$m _var = array_combine ($a _name, $a _flag);

Second, class naming

A the use of uppercase letters as a separate word, the other letters are in lowercase, that is, the hump format.

b The first letter of the first name uses uppercase

c) Do not use the underline ('_')

d) The interface interface is best to use the uppercase letter I and end with interface

For example:

Class Nameonetwo

Class Name

Interface Iexampleinterface ()

Third, the method name

A the use of uppercase letters as a separate word, and all other letters using lowercase

b The first letter of the name is capitalized, declared as "private" or "protected", using ' _ ' as the prefix

c) Do not use the underline ('_')

d) (rules consistent with class naming)

E The accessors of an object are always prefixed with "get" or "set", and when a design pattern such as a single state mode (singleton) or a factory pattern (factory) is used, the method's name should contain the name of the pattern, so that it is easy to identify the design pattern from the name.

For example:

Class nameonetwo{

Public Function DoIt () {};

Protect function _handleerror () {};

Private Function _sayhello () {};

}

Four, class attribute naming

A the attribute name prefix should be specified as a property value type (specific reference variable naming rule)

b prefix followed by a rule that is consistent with the class name

c The private attribute is prefixed with ' _ '

For example:

Class Nameonetwo {

Public Function Varabc () {};

Public Function ErrorNumber () {};

Public $iAge;

Private $_iage;

}

Name of the parameter in the method

A) reference class attribute naming

For example:

Class Nameonetwo {

Public Function Varabc ($SMSG) {};

}

Six, global variables

A the global variable should be prefixed with ' g '

b The rest of the reference variable naming rules

For example:

Global $gi _age;

Global $ga _price

Vii. defining named/Global constants

A global constant uses ' _ ' to split each word

b) all letters using uppercase

For example:

Define (' E_error_missing_para ', 501);

Eight, function

A) All letters in lowercase, using ' _ ' to separate each word

For example:

function Some_bloody_function () {

}

Nine, curly braces {} rules

(a) Place the curly braces at the same column or peer below the keyword, recommended to the peer

For example:

function Some_bloody_function () {

}

if (true) {

Code

}

Ten, Indent/tab rules

A) using tab indents

For example:

function Some_bloody_function () {

if (true) {

Code

}

}
