//创建一个要新生成的文件名
$string = (string) mt_rand(0, 10000) . &#39;IMG&#39;;

//读取本地图片
$file_path = &#39;./timg.jpg&#39;;

//1. 取出图片数据
$fq_1 = fopen($file_path, &#39;rb&#39;);
$imgData = fread($fq_1, filesize($file_path));
fclose($fp_1);

//2. 写入图片数据
$fp = fopen($string, &#39;wb&#39;);
//$str = fread($fp,filesize($file_path));
fwrite($fp, $imgData);
fclose($fp);

?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
</head>
<body>
    <img src="./<?php echo $string; ?>" alt="" title="" />
