1.Installation

The recommended way to install the SQL Query Formatter is through Composer. Run the following command to install it:

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

2. Features

Human readable SQL formatting

• Human readable plain text. No colours, no highlighting. Plain text is good enough in most cases.

Data Binding Awareness

• SQL Query Formatter takes data binding seriously.
• Placeholder syntax such as :variable or ? is taken into account and is preserved when formatting.

3. Usage

Sample code:

<?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);

Real output:

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. Fully tested

Testing has been done using PHPUnit and Travis-CI. All code has been tested to be compatible from PHP 5.4 up to PHP 5.6 and HHVM (nightly release).

To run the test suite, you need Composer:

    php composer.phar install --dev
    bin/phpunit
