📜 History of PHP Graph Lib

The first version of PHP Graph Lib was created by Elliott Brueggeman in late 2007 🙂 — almost 20 years ago! Good things really do stand the test of time.

You can thank Elliott Brueggeman by giving stars to his repositories or following him. Remember, he created this library under the MIT License and made it freely available. Today, it remains one of the best PHP libraries for creating graphs and pie charts under the MIT License.

Since 2007 and the first version of this library PHP versions have changed and so the library evolved. Current version is compatible with PHP 8.2.

Current repo is forked from repository of Troopster19 and at the moment of forking code was under MIT licence.

❓ What does this package do?

This package allows you to create graph and pie chart images. You have several options for handling images, including:

Displaying image from php memory
Save image to storage in Laravel and later handle that image
Save image to public directory in Laravel. This way you have public access to this image. This package provides URL for public images.

🚀 Installation

Requirements

PHP >= 8.0
Laravel >= 9
PHP Extensions:
- GD library (ext-gd)

Composer Installation

composer require noki/laravel-php-graph

⚙️ PHP GD Extension Setup

Linux (Debian/Ubuntu)

sudo apt-get update
sudo apt-get install php-gd

Example for PHP 8.3 — be sure to use the correct package names:

First, check your PHP version:

php -v

Then install GD for your version:

sudo apt-get install php8.3-gd

To verify if GD is installed:

php -m | grep gd

macOS (with Homebrew)

brew install php
# OR, if PHP is already installed:
brew reinstall php

The GD extension (gd) is bundled with PHP on macOS. No extra installation is usually required.

To confirm GD is enabled:

php -m | grep gd

Windows

Open your php.ini file.
Ensure the following line is uncommented (remove the ; at the beginning):

extension=gd

Restart your web server (Apache, Nginx) or PHP-FPM.

Verify installation

Run the following command to check if GD is enabled:

php -m | findstr gd

📦 Usage

Namespace

use Noki\PhpGraph\Graph;

1. Create a private graph (not publicly accessible)

        $data = array(
            12124,
            5535,
            43373,
            22223,
            90432,
            23332,
            15544,
            24523,
            32778,
            38878,
            28787,
            33243,
            34832,
            32302
        );

        $graph = new Graph(500, 350);

        $graph->setTitle('Widgets Produced');
        $graph->setGradient('red', 'maroon');
        $graph->addData($data);
        $file_path = $graph->createGraph('my_file_name' ,'F');

With line

$file_path = $graph->createGraph('my_file_name' ,'F');

it is set file name without extension or directory root. Parameter 'F' is used for output to file. This file will be saved in storage/app/private/php-graph-data directory inside Laravel.

File will be saved at that route and in variable $file_path will be set route to graph image.

Important notes:

Only ASCII codes are allowed in texts in PHP Graph Lib.

Since the output image format is always PNG, you do not need to set a file extension — any extension you provide will be ignored and .png will be automatically added.

Also, if you include a directory path in the file name, it will be removed, because all images are saved in the storage/app/private/php-graph-data directory.

2. Create a public graph (publicly accessible)

Use same code as above for graph drawing just change last line

$file_url = $graph->createGraph('my_file_name' ,'U');

This way image will be saved to public/images/php-graph-data/ directory. This image will be publicly accessible. In variable $file_url will be returned URL to this image.

Important note:

Only ASCII codes are allowed in texts in PHP Graph Lib.

Since the output image format is always PNG, you do not need to set a file extension — any extension you provide will be ignored and .png will be automatically added.

Also, if you include a directory path in the file name, it will be removed, because all images are saved in the public/images/php-graph-data directory.

3. Save image in PHP memory and display it without save to server

This is example of creating image from Controller.

Create route in routes/web.php

Route::get('/testing', [TestController::class, 'testing']);

Create controller in app/Http/TestController.php

<?php

namespace App\Http\Controllers;

use Noki\PhpGraph\Graph;

class TestController extends Controller
{
    public function testing()
    {
        $data = array(
            12124,
            5535,
            43373,
            22223,
            90432,
            23332,
            15544,
            24523,
            32778,
            38878,
            28787,
            33243,
            34832,
            32302
        );

        $graph = new Graph(500, 350);

        $graph->setTitle('Widgets Produced');
        $graph->setGradient('red', 'maroon');
        $graph->addData($data);
        $image_content = $graph->createGraph();

        return response($image_content)->header('Content-Type', 'image/png');

    }

}

Summary of options

Save to file for internal use:

$graph->createGraph('my_file_name' ,'F');

Save to file and file can be publicly accessed:

$graph->createGraph('my_file_name' ,'U');

Save to memory

$graph->createGraph();

🛠 Error Handling

If the GD library cannot be loaded, a PhpGraphException will be thrown.

🧩 Integration with Laravel

You can easily use this package in your controllers, services, or jobs by importing the relevant namespaces:

use Noki\PhpGraph\Graph;
use Noki\PhpGraph\PieGraph;
use Noki\PhpGraph\StackedGraph;

Once imported, you can create graphs and pie charts directly in your application.
