PHP通过url下载远程图片到本地

fopen

本文章从我一个ajax实例中提供了段关于通过图片地地址把图片保存到本址,这里我们直接通过readfile读取然后通过fopen保存即可

实例

 代码如下 复制代码

/**
 * 通过图片的远程url,下载到本地
 * @param: $url为图片远程链接
 * @param: $filename为下载图片后保存的文件名
 */
function GrabImage($url,$filename) {
 if($url==""):return false;endif;
 
 ob_start();
 readfile($url);
 $img = ob_get_contents();
 ob_end_clean();
 $size = strlen($img);
 
 //"../../images/books/"为存储目录,$filename为文件名
 $fp2=@fopen("../../images/books/".$filename, "a");
 fwrite($fp2,$img);
 fclose($fp2);
 
 return $filename;
 }
?>

函数返回图片下载完后保存的名字,那么只需在数据库中存储 图片目录+图片名即可。
