域名:http://localhost/down.php?add=down/0522/img.png (域名为随机)


$img = $add

echo $img;
?>
===================================================================

$img 只取图片的名称(img.png)

也就是说删除 (http://localhost/down?add=down/0522/)只取 (img.png)


什么写?求大神。


回复讨论(解决方案)

$img = basename($_GET['add']);

$img = basename($_GET['add']);


谢谢,能说说原理吗?新手求解、、、

url 参数通过 $_GET 数组获取,这是 php 的约定
basename 函数用于取得文件名(即去掉路径)
