Iterate through the icons in FontAwesome or get them as an array.

Wait. So what is this?

Simply put, this class was created to let you iterate over FontAwesome's icons for the purpose of building user interfaces in which one must be able to choose their own icons. That said, if you have another creative use for this, go for it!

This class extends PHP's built-in ArrayIterator class, returning an Icon class for each icon in your local copy of FontAwesome.

Requirements

1. PHP 5.2+
2. FontAwesome (Defaults created for 4.0+, but can be configured for any version.)

Installation

Via Composer

Just add the following to the require section your composer.json file:

"bca/fontawesomeiterator": "1.*"

Then execute composer install to pull down the latest release.

Package details can be found at https://packagist.org/packages/bca/fontawesomeiterator.

Via Github

You may download a specific version from https://github.com/brodkinca/BCA-PHP-FontAwesomeIterator/releases or visit the main repository at https://github.com/brodkinca/BCA-PHP-FontAwesomeIterator to download unreleased code or pull down a copy via git.

Basic Usage

1. Create an Instance of the Iterator

use BCA\FontAwesomeIterator\Iterator as FontAwesomeIterator;

$icons = new FontAwesomeIterator('path/to/fontawesome.css');

2. Do Something Useful

foreach loop

foreach ($icons as $icon) {
    echo $icon->class; // Do Something Here
}

while loop

while ($icons->valid()) {
    $icon = $icons->current();
    echo $icon->class; // Do Something Here
    $icons->next();
}

Advanced Usage

If you are using an older version of FontAwesome that still uses the icon- css prefix or a custom build of FontAweosme with a non-standard prefix it is necessary to define the prefix when instantiating the class.

Old Skool icon Prefix

Reqired for FontAwesome v3 and under.

$icons = new FontAwesomeIterator('path/to/fontawesome.css', 'icon');

Custom Prefix

$icons = new FontAwesomeIterator('path/to/fontawesome.css', 'my-custom-prefix');

NOTE: The prefix should be defined without any additional hyphenation. (i.e. prefix) NOT prefix-.

Example Implementation

Create a Select List of Icons by Name

<select>
<?php
    foreach ($icons as $icon) {
        echo '<option value="'.$icon->class.'">'.$icon->name.'</option>';
    }
?>
</select>

With the correct CSS it would also be possible to display the FontAwesome icon in the select list.

Icon Class

Each value returned by Iterator will be an instance of the Icon class.

Each Icon will have the current properties available:

• class CSS class of icon
• name Formatted name of icon (i.e. Angle (Right) )
• unicode Unicode representation of icon

Properties may be accessed by calling them directly upon the Icon class (i.e. $icon->name).

Versioning

This library will be maintained under the Semantic Versioning guidelines.

Releases will be numbered with the following format:

<major>.<minor>.<patch>

And constructed with the following guidelines:

• Breaking backward compatibility bumps the major (and resets the minor and patch)
• New additions without breaking backward compatibility bumps the minor (and resets the patch)
• Bug fixes and misc changes bump the patch

Composer users who would like more granular control over upgrades should restrict their installation to patch updates only using this require key:

"bca/fontawesomeiterator": "1.0.*"
