README

Enables parsing of expression's to a set of easy to navigate nodes.

Usage

Install the package using composer

composer require lydicgroup/filtering

<?php

require_once 'vendor/autoload.php';

$expression = 'name:eq:willem';
$lexer = new \LydicGroup\Filtering\ExpressionLexer();
$parser = new \LydicGroup\Filtering\ExpressionParser($lexer);
$nodes = $parser->parse($expression);

You can now use the nodes in whatever way you want.

Syntax

The syntax is basic, a single filter looks like this:

<property>:<operator>:<value>
name:eq:willem

You can chain multiple filters together:

<property>:<operator>:<value> <logic> <property>:<operator>:<value>
name:eq:willem AND age:gt:10

You can also group filters together:

<property>:<operator>:<value> <logic> (<property>:<operator>:<value> <logic> <property>:<operator>:<value>)
name:eq:willem AND (age:gt:10 OR city:neq:amsterdam)
