README

A configurable PHP solution to auto generate favicons and HTML tags from a original PNG file.

What does this package do?

In short, it will help you display correct favicon for your website with just one original PNG image.

In more details, it supports:

• create one ICO file and many PNG files with many favicon sizes from just one original PNG image as well as a manifest.json file for Android devices. Both input file path and output folder (which contains images and json files) are configurable via a command line interface.
• Generate suitable meta and link tags for desktop web browsers as well as mobile touch devices to properly display favicon.

Installation

We need PHP imagick extension or PHP GD extension for generating images. By default, the Imagick extension is loaded, if you cannot install it, you can switch to using GD via command line option if available.

You will need (Composer)[] to use this package. After install Composer, add this dependency into your composer.json file.

"hieu-le/favicon" : "~1.0"

Run composer update and start using.

Generate images

To use the command line to to generate favicon files:

$ vendor/bin/favicon generate [--ico-64] [--ico-48] [--no-old-apple] [--no-android] [--no-ms] [--app-name="..."] input [output]

Arguments:

• input: path to the input image files, which is required
• output: path to the folder which contains output files. If this folder does not exist, the package will try to create it. This argument is optional, default value is current folder.

Options:

• --use-gd: use GD extension instead of Imagick extension The Imagick ext is used by default. GD library is used if cannot load Imagick ext.
• --ico-64: include the 64x64 image inside the output ICO file (which contains only 16x16 and 32x32 images by default)
• --ico-48: include the 48x48 image inside the output ICO file (which contains only 16x16 and 32x32 images by default). Both --ico-48 and --ico-64 options make the output icon file larger a lot.
• --no-old-apple: exclude pngs files that used by old Apple touch devices
• --no-android: exclude manifest.json files and PNG files for Android devices
• --no-ms: exclude images for Windows tile
• --app-name="..." set the application name in the manifest.json file. Default is an empty string.

Output HTML tags

Call the favicon function inside your HTML template as follow:

echo favicon($option = FAVICON_ENABLE_ALL, array $msOptions = array())

The $option argument is a bitmask with following bit:

• FAVICON_NO_OLD_APPLE : do not include old apple touch link tags
• FAVICON_NO_ANDROID : do not include Android manifest.xml link tag
• FAVICON_NO_MS : do not include Windows and IE meta tags

The default value is FAVICON_ENABLE_ALL turns of all these three bit and include everything in the final output. Here are some examples:

• To exclude old apple touch link tags: FAVICON_NO_OLD_APPLE
• To exclude Android manifest file and IE meta tags: FAVICON_NO_ANDROID | FAVICON_NO_MS
• To exclude all these additional tags: FAVICON_NO_OLD_APPLE | FAVICON_NO_ANDROID | FAVICON_NO_MS

The $msOptions argument is an array contains information for Windows and IE. It can has these fields:

• tile_color: the background of live tile when this site is pinned, default is white (#ffffff)
• browser_config_file: the path to browser config XML file if you have it. By default, it is set to an empty string to prevent IE from auto looking browserconfig.xml file
• application_name: the default application name displayed when user pinned this site

The result of

echo favicon(FAVICON_ENABLE_ALL, array(
  'tile_color' => '#F0F0F0', 
  'browser_config_file' => 'IEConfig.xml', 
  'application_name' => 'Hieu Le Favicon'
));
