A pure PHP SQL (non validating) parser w/ focus on MySQL dialect of SQL
SELECT
INSERT
UPDATE
DELETE
REPLACE
RENAME
SHOW
SET
DROP
CREATE INDEX
CREATE TABLE
EXPLAIN
DESCRIBE
Other statements are returned as an array of tokens. This is not as structured as the information available about the above types. See the ParserManual for more information.
Since the MySQL SQL dialect is very close to SQL-92, this should work for most database applications that need a SQL parser. If using another database dialect, then you may want to change the reserved words - see the ParserManual. It supports UNION, subqueries and compound statements.
The parser is a self contained class. It has no external dependencies. The parser uses a small amount of regex.
The focus of the parser is complete and accurate support for the MySQL SQL dialect. The focus is not on optimizing for performance. It is expected that you will present syntactically valid queries.
