PHP获取带域名的文件路径

获取文件时直接调用getFilePath即可

<?php
// 获得域名
function getDomain()
{
    if (isset($_SERVER["REQUEST_SCHEME"])){
        $domainName = $_SERVER["REQUEST_SCHEME"] . "://" . $_SERVER["HTTP_HOST"];
    }else{
        $protocol = ((!empty($_SERVER["HTTPS"]) && $_SERVER["HTTPS"] != "off") || $_SERVER["SERVER_PORT"] == 443) ? "https://" : "http://";
        $domainName = $protocol.$_SERVER['HTTP_HOST'];
    }
    return $domainName;
}
// 获取文件完整路径
function getFilePath($file)
{
    if (!$file)return is_array($file) ? [] : "";
    if (!is_array($file)){
        if (strpos($file, "http") === 0) {
            return $file;
        }else{
            return getDomain() . $file;
        }
    }else{
        foreach ($file as $k => $v){
            if (strpos($v, "http") === 0) {
                $file[$k] = $v;
            }else{
                $file[$k] = getDomain() . $v;
            }
        }
        return $file;
    }
}
$image = "/uploads/image.png";
echo getFilePath($image);
