Code naming specification for PHP programming

Here is a detailed description

The Theta class file is named after the. class.php, which is called with the Hump method, and the first letter is capitalized, for example Pay.class.php;
The Theta class name and directory _ file name are consistent. For example: The Directory of class name Zend_autoloader is zend/autoloader.class.php;
The name of the theta function uses lowercase letters and underscores. For example: GET_CLIENT_IP;
The Theta method is named using the Hump method, the first letter lowercase or using an underscore "_", such as Listcomment (), _getresource (), usually the method at the beginning of the underscore belongs to the private method;
The name of the theta attribute uses the Hump method, the first letter lowercase or the underscore "_", such as $username,$_instance, where the attribute at the beginning of the underscore is a private property;
Theta constants are named with uppercase letters and underscore "_", such as "Home_url";

Understand digestion:

1. Indentation and length of line

Indent 4 spaces, not tab (some editors can configure a tab to represent multiple spaces, note that they are spaces), and keep about 75-85 characters long per line

2. Control structure

This part of the most easy to ignore, but also affect the code aesthetic most important aspect, the example is very detailed, benefited.

The code is as follows

Copy Code

<?php if ((condition1) | | (Condition2)) { Action1; } elseif ((Condition3) && (Condition4)) { Action2; } else { DefaultAction; } ?> <?php Switch (condition) { Case 1: Action1; Break Case 2: Action2; Break Default DefaultAction; Break } ?> <?php if ($condition 1 || $condition 2) && $condition 3 && $condition 4 ) { code here } ?> <?php $a = $condition 1 && $condition 2 ? $foo: $bar; $b = $condition 3 && $condition 4 ? $foo _man_this_is_too_long_what_should_i_do : $bar; ?>

3. Function call

The code is as follows	Copy Code
<?php $var = foo ($bar, $baz, $quux); $short = foo ($bar); $long _variable = foo ($baz); ?>

4. Class name specification

The code is as follows	Copy Code
<?php Class Foo_bar { ... code goes here } ?>

5. Method name Specification (hump named)

The code is as follows	Copy Code
<?php function Foofunction ($arg 1, $arg 2 = ') { if (condition) { Statement } return $val; } ?>

6. Array definition Specification

The code is as follows	Copy Code
<?php $some _array = Array ( ' foo ' => ' Bar ', ' Spam ' => ' ham ', ); ?>
