Table of Contents
Changelog
Changes per release are documented with each github release.
You can find an overview here: https://github.com/ScientaNL/DoctrineJsonFunctions/releases
Installation
The recommended way to install DoctrineJsonFunctions is through Composer.
Run the following command to install the package:
composer require scienta/doctrine-json-functions
Alternatively, you can download the source code as a file and extract it.
Testing
This repository uses phpunit for testing purposes.
If you just want to run the tests you can use the docker composer image to install and run phpunit.
There is a docker-compose file with the correct mount but if you want to use just docker you can run this:
php8
docker run -it -v ${PWD}:/app scienta/php-composer:php8 /bin/bash -c "composer install && ./vendor/bin/phpunit"
Functions Registration
Doctrine ORM
Doctrine documentation: "DQL User Defined Functions"
<?php
use Scienta\DoctrineJsonFunctions\Query\AST\Functions\Mysql as DqlFunctions;
$config = new \Doctrine\ORM\Configuration();
$config->addCustomStringFunction(DqlFunctions\JsonExtract::FUNCTION_NAME, DqlFunctions\JsonExtract::class);
$config->addCustomStringFunction(DqlFunctions\JsonSearch::FUNCTION_NAME, DqlFunctions\JsonSearch::class);
$em = EntityManager::create($dbParams, $config);
$queryBuilder = $em->createQueryBuilder();
Symfony with Doctrine bundle
Symfony documentation: "DoctrineBundle Configuration"
# config/packages/doctrine.yaml
doctrine:
orm:
dql:
string_functions:
JSON_EXTRACT: Scienta\DoctrineJsonFunctions\Query\AST\Functions\Mysql\JsonExtract
JSON_SEARCH: Scienta\DoctrineJsonFunctions\Query\AST\Functions\Mysql\JsonSearch
Note that doctrine is missing a boolean_functions entry.
You can register boolean functions as string_functions
and need to compare them with = true
to avoid DQL parser errors.
For example, to check for existence of an element in a JSONB array, use andWhere('JSONB_EXISTS(u.roles, :role) = true)
.
Usage
Mind the comparison when creating the expression and escape the parameters to be valid JSON.
Using Mysql 5.7+ JSON operators
$q = $queryBuilder
->select('c')
->from('Customer', 'c')
->where("JSON_CONTAINS(c.attributes, :certificates, '$.certificates') = 1");
$result = $q->execute(array(
'certificates' => '"BIO"',
));
Using PostgreSQL 9.3+ JSON operators
Note that you need to use the function names. This library does not add support for custom operators like @>
.
$q = $queryBuilder
->select('c')
->from('Customer', 'c')
->where("JSON_GET_TEXT(c.attributes, 'gender') = :gender");
$result = $q->execute(array(
'gender' => 'male',
));
Boolean functions need to be registered as string functions and compared with true because Doctrine DQL does not know about boolean functions.
$q = $queryBuilder
->select('c')
->from('Customer', 'c')
->where('JSONB_CONTAINS(c.roles, :role) = true');
$result = $q->execute(array(
'role' => 'ROLE_ADMIN',
));
Using SQLite JSON operators
$q = $queryBuilder
->select('c')
->from('Customer', 'c')
->where("JSON_EXTRACT(c.attributes, '$.gender') = :gender");
$result = $q->execute();
DQL Functions
The library provides this set of DQL functions.

- JSON_QUERY(json_doc, path)
- Given a JSON document, returns an object or array specified by the path. Returns NULL if not given a valid JSON document, or if there is no match.
MariaDb 10.2.4 JSON operators
MariaDb 10.7.0 JSON operators
- JSON_EQUALS(json_doc, json_doc)
- Checks if there is equality between two json objects. Returns 1 if it there is, 0 if not, or NULL if any of the arguments are null.
- JSON_NORMALIZE(json_doc)
- Recursively sorts keys and removes spaces, allowing comparison of json documents for equality.

- executed as
JSONB_EXISTS(jsonb, text)
, equivalent to jsonb ? text
- JSONB_EXISTS_ALL(jsonb, array)
- executed as
JSONB_EXISTS_ALL(jsonb, array)
, equivalent to jsonb ?& array
- JSONB_EXISTS_ANY(jsonb, array)
- executed as
JSONB_EXISTS_ANY(jsonb, array)
, equivalent to jsonb ?| array
- JSONB_IS_CONTAINED(jsonb, jsonb)

jsondoc->'path'
in case of non-numeric path
(use with JSON objects)
- JSON_GET_TEXT(jsondoc, path)

- expands to
jsondoc#>>'path'
Please note that chaining of JSON operators is not supported.

json
or of the value at path
.
- JSON_VALID(json)
- Returns 1 if the argument
json
is well-formed JSON or 0 otherwise.
Aggregate functions

Extendability and Database Support
Architecture
Platform function classes naming rule is:
Scienta\DoctrineJsonFunctions\Query\AST\Functions\$platformName\$functionName
Adding a new platform
To add support of new platform you just need to create new folder Scienta\DoctrineJsonFunctions\Query\AST\Functions\$platformName
and implement required function there according to naming rules
Adding a new function
If you want to add new function to this library feel free to fork it and create pull request with your implementation.
Please, remember to update documentation with your new functions.
