复制代码 代码如下:
$message //文章内容
//正则(这个还不是)
$reg = "/
//把抠出来的 img 地址存放到 $img_array 变量中
preg_match_all($reg, $message, $img_array, PREG_PATTERN_ORDER);
//过滤重复的图片
$img_array = array_unique($img_array[1]);
第二步. 把$img_array 数组循环一下. 做图片保存和文章位置替换
复制代码 代码如下:
foreach ($img_array as $img){
//判断是否是自己网站上的 图片
if('xxx.com' != get_domain($img)){// 如果这个图片不是自己服务器上的
//读取图片文件
$Gimg = new GetImage();
$Gimg->source = $img;
$Gimg->save_to = './data/temp/';
$FILE = $Gimg->download(); //图片移动到本地
//保存到相册 得到图片保存的位置
$img_path = pic_save($FILE,0,'');
//文本路径替换
$message = str_replace($img, $img_path, $message);
}
}
....这时候 $message 里面已经图片已经替换为自己服务器本地的地址,并且图片也保存到自己的服务器上.
复制代码 代码如下:
//下面一个函数 和 类是从网络上找的.
//从url中获得域名
function get_domain($url){
$pattern = "/[w-]+.(com|net|org|gov|cc|biz|info|cn)(.(cn|hk))*/";
preg_match($pattern, $url, $matches);
if(count($matches) > 0) {
return $matches[0];
}else{
$rs = parse_url($url);
$main_url = $rs["host"];
if(!strcmp(long2ip(sprintf("%u",ip2long($main_url))),$main_url)) {
return $main_url;
}else{
$arr = explode(".",$main_url);
$count=count($arr);
$endArr = array("com","net","org","3322");//com.cn net.cn 等情况
if (in_array($arr[$count-2],$endArr)){
$domain = $arr[$count-3].".".$arr[$count-2].".".$arr[$count-1];
}else{
$domain = $arr[$count-2].".".$arr[$count-1];
}
return $domain;
}// end if(!strcmp...)
}// end if(count...)
}// end function
