if(isset($submit))
{
$name=$_FILES['img']['name'];
$type=$_FILES['img']['type'];

$size=($_FILES['img']['size'])/1024;

$ext=end(explode('.',$name));
if (($ext == "gif")
|| ($ext == "jpeg")
|| ($ext == "jpg")
|| ($ext =="png")
&& ($size > 30))
{

Answer 1

根据[PHP: end - Manual]，当您使用end()时，它会将数组中的最后一个元素作为引用传递。

你可以尝试一些事情：

请勿在{{1}}中使用explode()。声明end()时，请尝试进行爆炸：
$name
使用$name = explode( '.', $_FILES['img']['name'] );和array_slice()代替list()：
end()

任何一个都可能有用。

Answer 2

你得到＆＃39;注意：未定义的变量＆＃39;错误，因为您尝试使用变量而不首先初始化它。在您的HTML中，您使用的是＃fulltarget＆＃39;，但它仅在您提交表单后设置。如果你想摆脱这个通知，你应该在你的PHP开头标记之后添加$fulltarget = '';之类的内容。

如果要检查PHP end()函数文档http://php.net/manual/en/function.end.php，您将看到该函数将数组作为参数通过引用。要修复此错误，您应将explode()结果保存为变量，然后将该变量传递给end()函数。例如：$arr = explode('.', $name); $ext = end($arr);

在PHP编码中获取错误未定义的变量
