1. 安装

推荐通过Composer安装SQL查询格式化器。运行以下命令进行安装

php composer.phar require nilportugues/sql-query-formatter

2. 功能

人类可读的SQL格式化

人类可读的纯文本。没有颜色，没有高亮。纯文本在大多数情况下已经足够好。

数据绑定意识

SQL查询格式化器非常重视数据绑定。
考虑并保留占位符语法，如:variable或?，在格式化时保持不变。

3. 使用

示例代码

<?php
use NilPortugues\Sql\QueryFormatter\Formatter;

$query = <<<SQL
SELECT user.user_id, user.username, (SELECT 
role.role_name FROM role WHERE (role.role_id = :v1) 
LIMIT :v2, :v3 ) AS user_role, (SELECT 
role.role_name FROM role WHERE (role.role_id = :v4)
LIMIT :v5, :v6 ) AS role FROM user WHERE (user.user_id = :v7)
SQL;

$formatter = new Formatter();
echo $formatter->format($query);

实际输出

SELECT
    user.user_id,
    user.username,
    (
        SELECT
            role.role_name
        FROM
            role
        WHERE
            (role.role_id = :v1)
        LIMIT
            :v2,
            :v3
    ) AS user_role,
    (
        SELECT
            role.role_name
        FROM
            role
        WHERE
            (role.role_id = :v4)
        LIMIT
            :v5,
            :v6
    ) AS role
FROM
    user
WHERE
    (user.user_id = :v7)

4. 完全测试

测试已使用PHPUnit和Travis-CI进行。所有代码均已测试，以确保与PHP 5.4至PHP 5.6以及HHVM (夜间发布)兼容。

要运行测试套件，您需要Composer

    php composer.phar install --dev
    bin/phpunit
