Question

哪种格式正确？我还不知道如何缩进PHP代码。我觉得Set 2是正确的，但我还不知道。

$connection = mysqli_connect('localhost', 'ijdbuser', 'ijdbpw');

if (!$connection)
{
    $error = 'Unable to connect to the database server.';
    include 'error.html.php';
    exit();
}

if (!mysqli_set_charset($connection, 'utf8'))
{
    $output = 'Unable to set database connection encoding.';
    include 'output.html.php';
    exit();
}

if (!mysqli_select_db($connection 'ijdb'))
{
    $error = 'Unable to locate the joke database.';
    include 'error.html.php';
    exit();
}

    $result = mysqli_query($connection, "SELECT joketext FROM joke");

        if (!$result)
        {
            $error = 'Error fetching jokes: ' . mysqli_error($connection
            );
            include 'error.html.php';
            exit();
        }

                while ($row = mysqli_fetch_array($result))  
                {  
                    $jokes[] = $row['joketext'];  
                }  
                include 'jokes.html.php';  

?>

Answer 1

没有＆＃34;对＆＃34; 或＆＃34;错误＆＃34; 格式化，而不是真的。只要保持一致，选择你最喜欢的风格。但是，有PHP-FIG这样的事情。他们提出的编码风格是最常用的编码风格，而且几乎所有主要的开源项目都会使用它。

就个人而言，我尝试尽可能多地订阅他们的编码标准，尽管我倾向于选择allman风格的括号（if ()\n{\n）。我想我几年前给他们发了一份公关，以便允许这种缩进方式，但它被拒绝了（主要是为了避免因冲突空白的合并冲突，所以我明白他们来自哪里）。

Answer 2

PSR - 这些不是类似法律的规则，但如果你遵循这些规则就不会错。

Answer 3

请使用此。 PHP美化也可以帮助很多。

<?php
$connection = mysqli_connect('localhost', 'ijdbuser', 'ijdbpw');

if (!$connection)
    {
    $error = 'Unable to connect to the database server.';
    include 'error.html.php';

    exit();
    }

if (!mysqli_set_charset($connection, 'utf8'))
    {
    $output = 'Unable to set database connection encoding.';
    include 'output.html.php';

    exit();
    }

if (!mysqli_select_db($connection'ijdb'))
    {
    $error = 'Unable to locate the joke database.';
    include 'error.html.php';

    exit();
    }

$result = mysqli_query($connection, "SELECT joketext FROM joke");

if (!$result)
    {
    $error = 'Error fetching jokes: ' . mysqli_error($connection);
    include 'error.html.php';

    exit();
    }

while ($row = mysqli_fetch_array($result))
    {
    $jokes[] = $row['joketext'];
    }

include 'jokes.html.php';

?>

似乎更具可读性。是的，清洁，可读性，清晰，易于维护是一些因素，而不仅仅是标准。查看Proposed Standards Recommendation (PSR)，还可以查看不同的php 开源框架及其样式指南或github上的编码约定或贡献样式指南。

例如：

Zend Framework Styleguide
Laravel 5使用PSR-4和PSR-1

我选择项目的团队和社区/组织最适合的......流体。
