更改 php 中逗号的颜色

Question

这是我的代码：

<?php
$posttags = get_the_tags();
if ($posttags) {
   $tagstrings = array();
   foreach($posttags as $tag) {
      $tagstrings[] = '<a href="' . get_tag_link($tag->term_id) . '" class="tag-link-' . $tag->term_id . '">' . $tag->name . '</a>';
   }
   echo implode(', ', $tagstrings);
}

// For an extra touch, use this function instead of `implode` to a better formatted string
// It will return "A, B and C" instead of "A, B, C"
function array_to_string($array, $glue = ', ', $final_glue = ' and ') {
    if (1 == count($array)) {
        return $array[0];
    }
    $last_item = array_pop($array);
    return implode($glue, $array) . $final_glue . $last_item;
}
?>

代码在 WP 中的标签后放置一个逗号（最后一个标签除外）。我想改变逗号的颜色。我该怎么做？

Answer 1

你可以这样使用：

$glue = '<span class="tagglue">,</span> ';

并在您的 implode() 调用中使用它（在您的代码段中的任一位置）。

然后创建一个 css 声明，例如：

.tagglue {color: blue;}

实施：

<?php
$posttags = get_the_tags();
if ($posttags) {
   $tagstrings = array();
   foreach($posttags as $tag) {
      $tagstrings[] = '<a href="' . get_tag_link($tag->term_id) . '" class="tag-link-' . $tag->term_id . '">' . $tag->name . '</a>';
   }
   echo array_to_string($tagstrings);
}

// For an extra touch, use this function instead of `implode` to a better formatted string
// It will return "A, B and C" instead of "A, B, C"
function array_to_string($array, $glue = '<span class="tagglue">, </span>', $final_glue = ' and ') {
    if (1 == count($array)) {
        return $array[0];
    }
    $last_item = array_pop($array);
    return implode($glue, $array) . $final_glue . $last_item;
}
?>

我会将此更改应用于 link Whosebug 上的几个相关页面（不提供着色）：

Implode array with ", " and add "and " before last item
Imploding with "and" in the end?
implode() an array with multiple database columns, except on last entry PHP
Comma separated list from array with "and" before last element
PHP Add commas to items with AND
Replace the last comma with an & sign
