获取字体真棒的所有类名列表

Question

我允许用户从管理面板添加他们选择的图标（fontawesome）。

因此，为了向用户显示图标（以及以后使用它们），我需要一个所有图标的 css 名称列表。

我在 SO 上看过类似的问题，大多数答案都建议刮掉 font awesome 网站的备忘单页面。

备忘单页面包含最新的字体真棒图标。但是，我不想向用户显示最新的图标，而我可能会在后端使用较旧的图标。两者都应该使用相同的图标。

所以，我需要一种方法来从字体很棒的 css 文件中刮取类名，我有。 或者可能是其他一些解决方案，通过它我可以在管理面板上向用户显示图标，然后在后端使用相同的列表。

我已经有一个可行的解决方案（在答案中提供），但正在寻找更好/有效的方法。

Answer 1

我正在使用_variables.scss font-awesome 文件（Scss 版本）来抓取图标类名称。

_variables.scss的内容如下：

// Variables
// --------------------------

$fa-font-path:        "../fonts" !default;
$fa-font-size-base:   14px !default;
//$fa-font-path:        "//netdna.bootstrapcdn.com/font-awesome/4.3.0/fonts" !default; // for referencing Bootstrap CDN font files directly

我正在使用php 来抓取图标类名称。我的解决方案如下。

// Fetch variables scss file in variable
$font_vars = file_get_contents('<asset_directory>/_variables.scss');

// Find the position of first $fa-var , as all icon class names start after that
$pos = strpos($font_vars, '$fa-var');

// Filter the string and return only the icon class names
$font_vars = substr($font_vars, $pos);

// Create an array of lines
$lines = explode("\n", $font_vars);


    $fonts_list = array();
    foreach($lines as $line) {
        // Discard any black line or anything without :
    if(strpos($line, ':') !== false) {
        // Icon names and their Unicode Private Use Area values are separated with : and hence, explode them.
        $t = explode(":", $line);

        // Remove the $fa-var with fa, to use as css class names.
        $fonts_list[str_replace('$fa-var', 'fa', $t[0])] = $t[1];
    }
}
echo '<pre>';
print_r($fonts_list);
echo '</pre>';
