Lost for how to include

[theDanielJLewis]

Please treat me like I know almost nothing about Composer.

How do I actually get JSONPath into my project? After running composer require flow/jsonpath dev-master or composer require flow/jsonpath, my PHP looks essentially like this:

<?php
require (__DIR__ . '/vendor/autoload.php');

$data = ['people' => [['name' => 'Joe'], ['name' => 'Jane'], ['name' => 'John']]];
$result = (new JSONPath($data))->find('$.people.*.name'); // returns new JSONPath

But I get the error "Class 'JSONPath' not found."

I'm doing something wrong, but I don't know what.

Hi Daniel,

You need to include the use statement at the top of your file so that PHP knows which namespace to use when looking for the class.

<?php
use Flow\JSONPath\JSONPath;
require (__DIR__ . '/vendor/autoload.php');

you can also use a fully qualified namespace + class name eg:
$result = (new \Flow\JSONPath\JSONPath($data))->find('$.people.*.name');

Composer packages and PHP 5.3+ code uses namespaces to avoid naming conflicts in class names and is a good thing to get familiar with:
https://www.php.net/manual/en/language.namespaces.rationale.php

Hope that helps!
