Format and highlight SQL statements in PHP

jdorn/sql-formatteris a lightweight PHP class used to format SQL statements.

It supports automatic indentation, adding newlines, and even supports syntax highlighting.

Used in the command line

This extension package contains abin/sql-formatterexecutable file, which can be used directly for command line formatting SQL.

You can use this command after installing Composer globally:

composer global require jdorn/sql-formatter sql-formatter "SELECT SOME QUERY;" // 直接格式化 // 或 echo "SELECT SOME QUERY;" | sql-formatter // 使用管道，更适合较大量的 SQL 语句

Use it as an extension package

The SqlFormatter class contains a static file named format. Method, which can receive a SQL statement string as a parameter and return formatted HTML code wrapped in pre tags.

For example:

= NOW()) ) GROUP BY Column1 ORDER BY Column3 DESC LIMIT 5,10"; echo SqlFormatter::format($query);

Output:

##Only formatting without highlighting

If you do not need highlighting and only need to add indentation and line breaks, please set the second parameter to false.

Suitable for outputting error logs or other non-HTML data.

      
Output:
      

      

      
Only highlight without formatting
There is a separate method named highlight It can ensure that the original format is not changed, and only syntax highlighting is added.
      
Applies to when the SQL has been well formatted and needs to be made more readable.
      

      

      
Compress query statement
The compress method can remove all SQL comments and compress unnecessary spaces.
      
Suitable for outputting multiple query statements and making them easy to copy and paste into the command line.
      

      
-- This is a comment SELECT /* This is another comment On more than one line */ Id #This is one final comment as temp, DateCreated as Created FROM MyTable; echo SqlFormatter::compress($query);
      
Output:
      

      
SELECT Id as temp, DateCreated as Created FROM MyTable;
      

      
Remove comments
If you need to keep the original format, but still need to delete the SQL comments, you can use the removeComments method to replace compress.
      

      
-- This is a comment SELECT /* This is another comment On more than one line */ Id #This is one final comment as temp, DateCreated as Created FROM MyTable; echo SqlFormatter::removeComments($query);
      
Output:
      

      
SELECT Id as temp, DateCreated as Created FROM MyTable;
      

      
Split multiple SQL statements into arrays
There is also a feature that has nothing to do with formatting, which can split multiple SQL statements into arrays. SQL statements are separated into arrays.
      
For example:
      

      
DROP TABLE IF EXISTS MyTable; CREATE TABLE MyTable ( id int ); INSERT INTO MyTable (id) VALUES (1),(2),(3),(4); SELECT * FROM MyTable; $queries = SqlFormatter::splitQuery($sql);
      
Result:
      

      
DROP TABLE IF EXISTS MyTable; CREATE TABLE MyTable ( id int ); INSERT INTO MyTable (id) VALUES (1),(2),(3),(4); SELECT * FROM MyTable;
