gFontDownloader

gFontDownloader is a PHP tool that allows you to download Google Fonts and create local CSS files for them.

Features

• Download Google Fonts to a local directory
• Create local CSS files for the downloaded fonts
• PSR-3 compatible logging

Configuration

You can configure gFontDownloader using one of the following methods:

1. Set configuration in config.json and call ->setConfig()
2. Set configuration via ->setConfig([array of configuration key-value pairs])
3. Set configuration via ->setConfig($key, $value)

Combinations of these methods are possible.

Configuration Options

• output: Directory where fonts are downloaded to (each font family will have its own subdirectory). Defaults to ./
• formats: Optional array of font formats to be downloaded. Defaults to all valid values. Valid values are: eot, woff, woff2, svg, ttf
• onRecoverableError: How to handle recoverable errors. Valid values are: stop (default), recover

Adding Fonts to Download List

You can add fonts to the download list using one of the following methods:

• ->addFont(string $fontFamily, string $fontStyle, array $fontWeights)

or

• ->addFontByUrl(string $urlOfFont)

Examples:

• "https://fonts.google.com/?selection.family=Gelasio:500i,700|Open+Sans|Roboto"
• "https://fonts.googleapis.com/css?family=Gelasio:500i,700|Open+Sans|Roboto&display=swap"

Running the Downloader

To start the download process, call ->download(). This method:

• Returns an array of all downloaded fonts
• Accepts a callback function that is passed information on each font individually

Error Handling

In case of unrecoverable errors, you can run ->createFamilyCssFiles() to create Font Family CSS files for fonts that were successfully downloaded before the error occurred (see example.php).

Logging

You can use PSR-3 compatible loggers with gFontDownloader:

->setLogger(new \PSRCompatibleLogger());

Example Usage

Here is an example of how to use gFontDownloader:

<?php

require 'vendor/autoload.php';

use smtws\gFontDownloader;

// Create a new instance of the downloader
$downloader = new gFontDownloader();

// Set configuration
$downloader->setConfig([
    'output' => 'fonts/',
    'formats' => ['woff2', 'ttf'],
    'onRecoverableError' => 'recover'
]);

// Add fonts to the download list
$downloader->addFont('Gelasio', 'italic', [500, 700]);
$downloader->addFontByUrl('https://fonts.googleapis.com/css?family=Open+Sans|Roboto&display=swap');

// Set a logger (optional)
$downloader->setLogger(new \MyLogger());

// Run the downloader
$downloadedFonts = $downloader->download();

// Handle downloaded fonts
foreach ($downloadedFonts as $font) {
    echo "Downloaded font: " . $font['family'] . "\n";
}
