使用 PHP 实现 Cravatar 非常简单。 PHP 提供了 strtolower()
、 md5()
、 和 urlencode()
函数,让我们可以轻松创建头像 URL 。假设以下数据:
$email = "someone@somewhere.com";
$default = "https://www.somewhere.com/homestar.jpg";
$size = 40;
您可以使用以下 php 代码构建您的头像 url:
$crav_url = "https://cravatar.cn/avatar/" . md5( strtolower( trim( $email ) ) ) . "?d=" . urlencode( $default ) . "&s=" . $size;
创建头像 URL 后,您可以随时输出:
<img src="<?php echo $crav_url; ?>" alt="" />
实施示例
此功能将允许您使用 PHP 快速轻松地将 Cravatar 插入页面中:
/**
* Get either a Cravatar URL or complete image tag for a specified email address.
*
* @param string $email The email address
* @param string $s Size in pixels, defaults to 80px [ 1 - 2048 ]
* @param string $d Default imageset to use [ 404 | mp | identicon | monsterid | wavatar ]
* @param string $r Maximum rating (inclusive) [ g | pg | r | x ]
* @param boole $img True to return a complete IMG tag False for just the URL
* @param array $atts Optional, additional key/value attributes to include in the IMG tag
* @return String containing either just a URL or a complete image tag
* @source https://cravatar.com/developer/php-image-requests

function get_cravatar( $email, $s = 80, $d = 'mp', $r = 'g', $img = false, $atts = array() ) {
$url = 'https://cravatar.cn/avatar/';
$url .= md5( strtolower( trim( $email ) ) );
$url .= "?s=$s&d=$d&r=$r";
if ( $img ) {
$url = '<img src="' . $url . '"';
foreach ( $atts as $key => $val )
$url .= ' ' . $key . '="' . $val . '"';
$url .= ' />';
}
return $url;
