Google Trends API for PHP

Introduction

This is an unofficial Google Trends API for PHP.

Please notice that the good functionality of this API depends on Google's willing to keep the backward compatibility and/or the parameters, naming and/or required values.
If this happens, feel free to contribute or open an issue.

Requirements

Please see the composer.json file.

Installation

Via Composer (require)

If you have composer installed globally

$ composer require x-fran/g-trends

If you use composer.phar local

# Get your own copy of composer.phar
$ curl -s https://getcomposer.org/installer | php -- --filename=composer
$ composer require "x-fran/g-trends": "^1.0"

Via Composer (create-project)

You can use the create-project command from Composer to create the project in one go (you need to install composer):

$ curl -s https://getcomposer.org/installer | php -- --filename=composer
$ composer --no-dev create-project x-fran/g-trends path/to/install

Via Git (clone)

First, clone the repository:

$ git clone https://github.com/x-fran/g-trends.git # optionally, specify the directory in which to clone
$ cd path/to/install
$ curl -s https://getcomposer.org/installer | php -- --filename=composer

At this point, you need to use Composer to install dependencies. Assuming you already have Composer:

$ composer --no-dev install
