greenlion/php-sql-parser is a pure PHP SQL parser focusing on parsing MySQL dialect. It does not perform syntax verification, but can parse multiple types of SQL statements, including SELECT, INSERT, UPDATE, DELETE, etc. Its main features include:
- Comprehensive MySQL support : This parser supports multiple statement types in MySQL dialect, such as CREATE TABLE, DROP, SHOW, etc.
- No external dependencies : The parser is a self-contained class that requires no external dependencies and uses only a small number of regular expressions.
- Flexibility : Although mainly targeting MySQL, because the MySQL dialect is very close to SQL-92, it can also be used in other database applications. Other SQL dialects can be supported by tweaking the reserved words.
- Detailed parsing output : The parser can parse SQL statements into structured arrays, which facilitates subsequent processing and analysis.
Installation using Composer is very simple:
<code>composer require greenlion/php-sql-parser</code>
Here is a simple example showing how to use the parser:
<code class="php">use PHPSQLParser\PHPSQLParser; $sql = "SELECT STRAIGHT_JOIN a, b, c FROM some_table an_alias WHERE d > 5;"; $parser = new PHPSQLParser(); $parsed = $parser->parse($sql); print_r($parsed);</code>
The output result will be a structured array containing various parts of the SQL statement, such as SELECT, FROM, WHERE, etc. This allows us to easily extract and process key information in SQL statements.
In practical applications, this parser greatly simplifies my workflow and improves the efficiency of SQL statement processing. If you also need to parse and process SQL statements in PHP projects, greenlion/php-sql-parser is undoubtedly a very useful tool.
