    ▪PHP 采集心得技巧       1.获取远程文件源代码（file_get_contents或用fopen）. 2.分析代码得到自己想要的内容（这里用正规匹配，一般是得到分页）。 3.跟根得到的内容进行下载入库等操作。 　　在这里第二步有可能.........

代码如下:

}

代码如下:

/*本存图片函数*/
function getimg($url,$filename){
　　　　/*判断图片的url是否为空，如果为空停止函数*/
　　　　if($url==""){
　　　　　　　　return false;
　　　　}
　　　　/*取得图片的扩展名，存入变量$ext中*/
　　　　$ext=strrchr($url,".");
　　　　/*判断是否是合法的图片文件*/
　　if($ext!=".gif" && $ext!=".jpg"){
　　　　　　　　return false;
　　　　}
　　　　/*读取图片*/
　　　　$img=file_get_contents($url);
　　　　/*打开指定的文件*/
　　　　$fp=@fopen($filename.$ext,"a");
　　　　/*写入图片到指点的文件*/
　　　　fwrite($fp,$img);
　　　　/*关闭文件*/
　　　　fclose($fp);
　　　　/*返回图片的新文件名*/
　　　　return $filename.$ext;
